Central to the discussion of sub-liquidation value investing in Japan is the ability or willingness of shareholders to influence management, and management’s willingness to listen. As Ben Graham noted in the 1934 edition of Security Analysis, in the US:

The whole issue may be summarized in the form of a basic principle, viz:

When a common stocks sells persistently below its liquidating value, then either the price is too low, or the company should be liquidated. Two corollaries may be deduced from this principle:

Corollary I. Such a price should impel the stockholders to raise the question whether it is in their interest to continue the business.

Corollary II. Such a price should impel the management to take all proper steps to correct the obvious disparity between market quotation and intrinsic value, including a reconsideration of its own policies and a frank justification to the stockholders of its decision to continue the business.

The perception is that, in Japan, these two corollaries do not flow from that basic principle. As The Economist notes in a February 2008 article, Samurai v shareholders: Japan’s establishment continues to rebuff foreign activist investors (subscription required):

Japanese businessmen and politicians fear that the activists are short-term investors keen to strip firms of their cash. The conflict highlights a fundamental divide: companies in Japan are social institutions with a duty to provide stable employment and consider the needs of employees and the community at large, not just shareholders.

And therein lies the rub. Companies in Japan are social institutions with a duty to provide stable employment and consider the needs of employees and the community at large, not just shareholders.

Can foreign investors not subject to the cultural expectation that companies consider the needs of employees and the community at large succeed?

According to a 2009 Knowledge@Wharton article, How the Environment for Foreign Direct Investment in Japan Is Changing — for the Better, the environment for foreign investors in Japan is improving, but continues to be more bureaucratic than in the US:

Despite the support shown by elected officials for increasing [foreign direct investment] in Japan, foreign investors still face a substantial amount of bureaucratic red tape, particularly with respect to protected industries. [Direct investment] is principally governed by the Foreign Exchange and Foreign Trade Control Law, which specifically prevents foreign investors from acquiring a majority stake in Japanese companies within industry sectors classified as closely related to national security and public safety. This includes industries as diverse as aeronautics, defense, nuclear power generation, energy, telecom, broadcasting, railways, tourist transportation, petroleum and leather processing.

Foreign investors intending to make direct investments in certain industries must file with the Japanese Ministry of Finance as well as the respective ministry governing the specific industry of the investment target. If issues are found in relation to the investment, either the Ministry of Finance or the industry-specific ministry has the authority to issue an official recommendation to revise the investment plan or to put a complete stop to the acquisition. Industry-specific regulations that, for example, limit foreign ownership to one-third for airline and telecom companies, further constrain foreign investors.

It’s worth considering the experience of two notable activist campaigns in Japan. The first, Steel Partners’ campaign for Sapporo, the brewer, is described in the Knowledge@Wharton article:

Steel Partners has imported its U.S. activist investment model to Japan and has shown a willingness to question publicly the strategy of current management at its investment targets and to litigate disagreements.

As a result of Steel Partners’ posture, the firm’s take-over bid for household-brand Bulldog Sauce met with resistance from the media and Japan’s legal system. The court to which Steel Partners appealed a failed injunction to prevent Bulldog’s poison-pill strategy stated: “[Steel Partners] pursues its own interests exclusively and seeks only to secure profits by selling companies’ shares back to the company or to third parties in the short term, in some cases with an eye to disposing of company assets…. As such, it is proper to consider the plaintiff an abusive acquirer.”

The Economist article discusses the The Children’s Investment Fund’s (TCI) battle for the Japanese power provider J-Power:

The biggest showdown between the activists and the establishment is at J-Power, the former state-run energy firm, which was privatised in 2004. [TCI] a British fund, which owns 9.9% of the firm, has been politely but firmly lobbying J-Power to appoint two TCI representatives to its board, improve margins and unwind cross-shareholdings with other firms. Having been rebuffed, TCI now wants to double its bet. In January it asked for permission to increase its stake to 20% (any holding above 10% requires government approval). John Ho, the head of TCI’s Asian operations, says the deal is a test of the integrity of Japan’s reform agenda. And it would be, except that Mr Ho has chosen a remarkably hard case. Japan, lacking natural resources, is worried about energy security and is reluctant to hand more control over its power infrastructure to foreign investors.

The Knowledge@Wharton article concludes:

After applying for approval to increase shareholdings to 20%, TCI met a wall of resistance: J-Power management cautioned that TCI could cut maintenance and investment costs in nuclear plants, and the Japanese media relayed sensationalist warnings about the potential for “blackouts.” The result: The Japanese government blocked the investment.

These are not encouraging outcomes. The final word is best left to Takao Kitabata, the vice-minister of Japan’s powerful Ministry of Economy, Trade and Industry (METI):

To be blunt, shareholders in general do not have the ability to run a company. They are fickle and irresponsible. They only take on a limited responsibility, but they greedily demand high dividend payments.

High dividend payments? We’re a long way from liquidation as a matter of course.

Following on from last week’s Japanese liquidation value: 1932 US redux post, I’ve been trying to determine whether the historical performance of Japanese sub-liquidation value stocks matches the experience in the US. The question arises because of the perception (rightly or not) that the weakness of shareholder rights in Japan means that net current asset value stocks there are destined to trade at a discount to net current asset value. I’m always a little chary of the “Japan has weak shareholder rights” narrative (or any narrative, for that matter). I’d rather look at the data. In this instance, unfortunately, the data are wanting.

In The performance of Japanese common stocks in relation to their net current asset values, a 1993 paper by Bildersee, Cheh and Zutshi, the authors analyzed the performance of Japanese net nets between 1975 and 1988. Here are their findings described in another paper:

In the first study outside of the USA, Bildersee, Cheh and Zutshi (1993)’s paper focuses on the Japanese market from 1975 to 1988. In order to maintain a sample large enough for cross-sectional analysis, Graham’s criterion was relaxed so that firms are required to merely have an NCAV/MV ratio greater than zero. They found the mean market-adjusted return of the aggregate portfolio is around 1 percent per month (13 percent per year).

Not a great return, but obviously a difficult period through 1987 and not an exact facsimile of Graham’s strategy. An astute reader notes that “…the test period for that study is not the best. It includes Japan’s best analog to America’s Roaring Twenties. The Nikkei peaked on 12/29/89, and never recovered:”

Many of the “assets” on public companies’ books at that time were real estate bubble-related. At the peak in 1989, the aggregate market price for all private real estate in the city of Tokyo was purportedly greater than that of the entire state of California. You can see how the sudden runup in real estate during the bubble could cause asset-heavy companies to outperform the market.

So a better crucible for Japanese NCAVs might be the deflationary period, say beginning 1/1/90, which is more analogous to the US in 1932.

It would be interesting to see an update of the performance, but, as far as I am aware, none exists. To that end, I’ve undertaken a little research project of my own. I’ll publish the results tomorrow.

Farukh Farooqi, a long-time supporter of Greenbackd and the founder of Marquis Research, a special situations research and advisory firm (for more on Farukh and his methodology, see The Deal in the article “Scavenger Hunter”) provided a guest post on Silicon Storage Technology, Inc (NASDAQ:SSTI) a few weeks back. Farukh wrote:

Activist-Driven Situation Summary: Silicon Storage Tech. (SSTI; $2.78) dated January 6, 2010

SST is a fabless, designer and supplier of NOR flash memory chips which are used in thousands of consumer electronic products. It has two businesses – Products sales of $240 mm with 20% gross margin and licensing revenues of $40 mm with near 100% margin.

As of September 30, 2009, SST had cash and investments of $2.14 per share, net non-cash working capital of $0.41 per share and zero debt. This implies that the market is valuing its business at $0.23 per share or $22 mm. This is a Company which annually spends $50 mm on R&D alone!

Judging from last 10 years of SST’s history, valuation has suffered from (1) dismal bottom line performance and (2) Corporate governance issues.

After bottoming in Q109, Company revenues and margins have rebounded sharply. The Board has decided to take this opportune time to create “value” for shareholders by selling it to a private equity fund for … $2.10 per share. As part of the deal, the current CEO and COO are going to keep their equity interest in the private Company.

In response, an activist shareholder (Riley Invesment Management) resigned from the Board when the Go-Private deal was announced. Last week, he and certain other large shareholders formed SST Full Value Committee and have asked the Board to reconsider the transaction.

Given the governance issues (which could improve as a proxy fight to add independent members is underway), a discount to the peer group is warranted. However, whether you value it on EV/Revenue, EV/EBITDA or Price/Tangible Book Value, the stock has 50% to 200% upside potential.

Farukh has left a comment that I want to draw to your attention:

SSTI being acquired by MCHP for $2.85 per share.

Does this price make sense?

SSTI has $2.55 per share in cash, investments and net working capital. Which means, MCHP is really offering $0.35 per share in value or approximately $35 mm for a semiconductor business which generates $280 mm in sales and almost $50 mm per anum in gross profit and another $40 mm per year in license fees.

The license fees alone can be worth $200 mm using a 20% yield.

SST story reminds me of the Road Runners cartoon with management being the Wile E. Coyote, trying to sabotage shareholders every which way….. Beep Beep.

Mariusz Skonieczny is the founder and president of Classic Value Investors LLC and runs the Classic Value Investors website. He has provided me with a copy of his book Why Are We So Clueless about the Stock Market? Learn How to Invest Your Money, How to Pick Stocks, and How to Make Money in the Stock Market and has asked me to review it for the site. I am happy to do so.

Mariusz says that the purpose of this book is to “help readers understand the basics of stock market investing:”

Material covered includes the difference between stocks and businesses, what constitutes a good business, when to buy and sell stocks, and how to value individual stocks. The book also includes a chapter covering four case studies as well as a supplemental chapter on the pros and cons of real estate versus stock market investing.

The book discusses the basics of valuation through return on equity, how to identify a “good” businesses with sustainable competitive advantages (moats), diversification, how to understand the capital structure, and the implications of the economy for the business analyzed. Most usefully, Mariusz also discusses how to analyze an investment and provides several case studies discussing his methodology. In my opinion, the book is an excellent introduction to Buffett-style investing, and I would recommend it to investors seeking “wonderful companies at a fair price.”

In October I introduced a “monthly” net-net watch list based on the GuruFocus Benjamin Graham Net Current Asset Value Screener (subscription required). I haven’t updated it on a monthly basis, so now it’s a quarterly net-net watch list.

July Net-Net Screen

I was prompted to introduce the October net-net watch list because of the performance of a watch list created on July 7, 2009 using the July 6, 2009 closing prices. The performance of the stocks in that first watch list to October 13 was nothing short of spectacular. Here is a screen grab (with some columns removed to fit the space below):

GuruFocus NCAV Screen

The average return to October across the nine stocks in the watch list was 45.5% against the return on the S&P500 of 20.05% over the same period, an outperformance of more than 25% in ~three months. Pretty impressive stuff.

Here is the performance NCAV screen updated to today:

While a 16.38% return over ~6 months is a good return, given that the watch list was up 45.5% to October, the last quarter was, to say the least, a little disappointing. It’s also underperformed the S&P500 by 5.12%.

October Net-Net Screen

The stocks in the October watch list are set out below (again, with a column removed to fit the space below):

GuruFocus NCAV Screen 2009 10 13

Here’s the performance of the October crop to yesterday’s close:

36.85% is a fantastic return for a quarter, more so given that the S&P500’s return was so anaemic at 1.21%. It was obviously helped by the performance of NLST, up more than 428% for the period. If we remove NLST from the portfolio, the portfolio return drops to 10.7%, which is still a good return, but nowhere near as impressive.

February Net-Net Screen

I have captured the February screen which I’ll track over the coming months. If you want to see complete list online in real time, go to GuruFocus Benjamin Graham Net Current Asset Value Screener (subscription required).

In August last year Wes Gray and Andy Kern supplied the first Greenbackd guest post on CombiMatrix Corporation (NASDAQ:CBMX). The thesis was as follows:

There are a number of undervalued micro cap companies in this market, but not all values are created equal. Combimatrix (Symbol: CBMX) is a small biotech company that is tremendously undervalued by the market and has catalyst in place to realize its intrinsic value in the near term (~6months or less). Management is smart, downside is limited, and upside is huge( 100-200%+). There’s a lot to like at the current stock price.

Valuation

a. Cash

The company doesn’t appear to even remotely be a net-net by glancing at the balance sheet, however, closer inspection of the company’s contingent claims suggest otherwise. In 2005 the company won a lawsuit against National Union Fire Insurance relating to its director’s and officers’ insurance policy and was awarded a $32.1 million judgment by the US District Court. It was later awarded an additional $3.6 million by the court for attorneys’ fees and has continued to earn interest since this time.

National Union appealed, at which point the court required it to post an appellate bond of $39.2 million with the court. This means that the creditworthiness of National Union is not an issue and the only thing standing between CombiMatrix and the current value of the judgment is the Circuit Court. It appears very unlikely that the ruling will be overturned based on our legal due diligence: the decision was a bench verdict by a federal judge, and there were $0 dollars in punitive damages so the appeal theory is very weak. All briefs have been submitted to the court by both parties and only the oral hearing remains, meaning that a disbursement of the funds could happen soon. A decision is expected to be finalized by Q4 2009.

The $36mm lawsuit money and $10mm supplement represent $46mm. After the 20% lawyer fee we are left with ~30mm plus the $10mm supplemental (which we would likely do a settlement for 7mm to expediate process). Add back the $11mm cash balance on June 30, 2009 and the company is sitting on nearly $6.4 in cash per share (based on 7.5mm outstanding).

If we assume $3mm in cash burn and $12mm in liabilities (convert debt+misc liabilities+liquidation costs) at December 31, 2009, we are still left with a cash balance of [~$4.4] per share ($33mm/7.5mm s/o).

Read the rest.

CBMX has lodged the following notice:

On January 27, 2010, National Union Fire Ins. Co. of Pittsburgh, PA (“National Union”), Acacia Research Corporation and we entered into a settlement agreement (the “Settlement Agreement”), pursuant to which National Union has agreed to pay us $25.0 million by February 12, 2010 to settle the dispute. Consistent with the Settlement Agreement, we have not issued a press release with respect to this event as is our normal custom upon entry into material agreements.

The settlement seems to be at a reasonably substantial discount to the award, but this is a positive development. It will be interesting to see where the stock trades today.

CXO Advisory Group has uncovered a superb paper Stocks of Admired Companies and Spurned Ones by Deniz Anginer and Meir Statman, which finds that the most admired companies on Fortune Magazine’s annual survey of list of “America’s Most Admired Companies” had lower returns, on average, than stocks of spurned companies from April 1983 through December 2007. Further, Anginer and Statman find that increases in admiration were followed, on average, by lower returns.

Anginer and Statman describe their methodology as follows:

Fortune has been publishing the results of annual surveys of company reputations since 1983 and the survey published in March 2007 included 587 companies in 62 industries. Fortune asked more than 3,000 senior executives, directors and securities analysts to rate the ten largest companies in their own industries on eight attributes of reputation, using a scale of zero (poor) to ten (excellent): quality of management; quality of products or services; innovativeness; long-term investment value; financial soundness; ability to attract, develop, and keep talented people; responsibility to the community and the environment; and wise use of corporate assets. The rating of a company is the mean rating on the eight attributes. The list of admired companies in the 2007 survey includes Walt Disney, UPS and Google, with ratings of 8.44, 8.37 and 8.07. The list of spurned companies includes Jet Blue, Bridgestone and Stanley Works, with ratings of 5.25, 5.34 and 5.37.

The mean rating of companies in some industries, such as the 6.53 of the Communications industry, are higher on average than those of other industries, such as the 5.26 of the Agricultural Production industry. Our focus is on companies and we distinguish company effects from industry effect by using industry adjusted ratings of companies. They are the difference between the rating of a company and the mean rating of companies in its industry.

Consider two portfolios constructed by Fortune ratings; each consisting of one half of the Fortune stocks. The admired portfolio contains the stocks with the highest Fortune ratings and the spurned portfolio contains the stocks with the lowest. We construct the portfolios on April 1st of 1983, based on the Fortune survey published earlier that year1. We calculate the returns of the portfolios during the 12 months from April 1st 1983 to March 31st 1984 from daily returns. We reconstruct each portfolio on April 1st of subsequent years based on the Fortune survey published earlier that year and calculate returns similarly during the following 12 months.

CXO summarize the findings as follows:

  • Over the entire sample period, the mean annualized equally-weighted (value-weighted) return for the unadmired (lower half) portfolio is 18.3% (16.1%), compared to 16.3% (13.8%) for the admired (upper half) portfolio.
  • Risk-adjusted alphas of an annually reformed hedge portfolio that is long (short) the unadmired (admired) stocks is sometimes positive and sometimes insignificant, depending on whether the risk adjustment is beta only or multi-factor.
  • Increases in admiration generally indicate lower future returns. For example, the mean annualized equally-weighted return of the stocks in the most unadmired quartile for which reputation decreased (increased) relative to the median is 18.8% (13.2%).
  • The dispersion of returns is higher within the unadmired portfolio than the admired one. Among the 12 stocks with the worst (best) annual returns, 11 (9) come from the unadmired portfolio. Investors seeking to exploit “unadmiredness” should therefore diversify widely among unadmired stocks.
  • The effect is non-linear. The annualized return of an equally-weighted portfolio of the 10 least (most) admired stocks is 13.4% (16.6%). The next ten most and least admired stocks have about the same annualized return. However, for rankings 21-30, 31-40 and 41-50, unadmired stocks substantially beat admired stocks.
  • In summary, the stocks of companies unadmired by the ostensibly well-informed may well outperform the stocks of the companies admired.

Why might this be so? I’d like to venture a guess. Anginer and Statman’s findings would seem to accord with the findings of Josef Lakonishok, Andrei Shleifer, and Robert Vishny in Contrarian Investment, Extrapolation and Risk (and the The Brandes Institute update Value vs Glamour: A Global Phenomenon. Those two papers found that value stocks (defined as the lowest decile of stocks by price-to-book) outperformed glamour stocks (and by a wide margin).Recall that glamour stocks are those that “have performed well in the past,” and “are expected by the market to perform well in the future.” Value stocks are those that “have performed poorly in the past and are expected to continue to perform poorly.” LSV say value beats glamour because investors don’t fully appreciate the phenomenon of mean reversion, which leads them to extrapolate past performance too far into the future. It’s possible that “admired” can be a proxy for “glamourous” and therefore Anginer and Statman have identified another aspect of this phenomenon. Admired companies are bid up like glamour stocks, and scorned companies are ignored like value stocks, which creates the opportunity for contrarian bet. I love a counter-intuitive strategy.

In “Black box” blues I argued that automated trading was a potentially dangerous element to include in a quantitative investment strategy, citing the “program trading / portfolio insurance” crash of 1987. When the market started falling in 1987 the computer programs caused the writers of derivatives to sell on every down-tick, which some suggest exacerbated the crash. Here’s New York University’s Richard Sylla discussing the causes (care of Wikipedia).

The internal reasons included innovations with index futures and portfolio insurance. I’ve seen accounts that maybe roughly half the trading on that day was a small number of institutions with portfolio insurance. Big guys were dumping their stock. Also, the futures market in Chicago was even lower than the stock market, and people tried to arbitrage that. The proper strategy was to buy futures in Chicago and sell in the New York cash market. It made it hard — the portfolio insurance people were also trying to sell their stock at the same time.

The Economist’s Buttonwood column has an article, Model behaviour: The drawbacks of automated trading, which argues along the same lines that automated trading is potentially problematic where too many managers follow the same approach:

[If] you feed the same data into computers in search of anomalies, they are likely to come up with similar answers. This can lead to some violent market lurches.

Buttonwood divides the quantitative approaches to investing into at three different types and their potential for providing a stabilizing influence on the market or throwing fuel on the fire in a crash:

1. Trend-following, the basis of which is that markets have “momentum”:

The model can range across markets and go short (bet on falling prices) as well as long, so the theory is that there will always be some kind of trend to exploit. A paper by AQR, a hedge-fund group, found that a simple trend-following system produced a 17.8% annual return over the period from 1985 to 2009. But such systems are vulnerable to turning-points in the markets, in which prices suddenly stop rising and start to fall (or vice versa). In late 2009 the problem for AHL seemed to be that bond markets and currencies, notably the dollar, seemed to change direction.

2. Value, which seeks securities that are  cheap according to “a specific set of criteria such as dividend yields, asset values and so on:”

The value effect works on a much longer time horizon than momentum, so that investors using those models may be buying what the momentum models are selling. The effect should be to stabilise markets.

3.  Arbitrage, which exploits price differentials between securities where no such price differential should exist:

This ceaseless activity, however, has led to a kind of arms race in which trades are conducted faster and faster. Computers now try to take advantage of arbitrage opportunities that last milliseconds, rather than hours. Servers are sited as close as possible to stock exchanges to minimise the time taken for orders to travel down the wires.

In arguing that automated trading can be problematic where too many managers pursue the same strategy, Buttonwood gives the example of the August 2007 crash, which sounds eerily similar to Sylla’s explanation for the 1987 crash above:

A previous example occurred in August 2007 when a lot of them got into trouble at the same time. Back then the problem was that too many managers were following a similar approach. As the credit crunch forced them to cut their positions, they tried to sell the same shares at once. Prices fell sharply and portfolios that were assumed to be well-diversified turned out to be highly correlated.

It is interesting that over-crowding is the same problem identified by GSAM in Goldman Claims Momentum And Value Quant Strategies Now Overcrowded, Future Returns Negligible. In that presentation, Robert Litterman, Goldman Sachs’ Head of Quantitative Resources, said:

Computer-driven hedge funds must hunt for new areas to exploit as some areas of making money have become so overcrowded they may no longer be profitable, according to Goldman Sachs Asset Management. Robert Litterman, managing director and head of quantitative resources, said strategies such as those which focus on price rises in cheaply-valued stocks, which latch onto market momentum or which trade currencies, had become very crowded.

Litterman argued that only special situations and event-driven strategies that focus on mergers or restructuring provide opportunities for profit (perhaps because these strategies require human judgement and interaction):

What we’re going to have to do to be successful is to be more dynamic and more opportunistic and focus especially on more proprietary forecasting signals … and exploit shorter-term opportunistic and event-driven types of phenomenon.

As we’ve seen before, human judgement is often flawed. Buttonwood says:

Computers may not have the human frailties (like an aversion to taking losses) that traditional fund managers display. But turning the markets over to the machines will not necessarily make them any less volatile.

And we’ve come full circle: Human’s are flawed, computers are the answer. Computers are flawed, humans are the answer. How to break the deadlock? I think it’s time for Taleb’s skeptical empiricist to emerge. More to come.
