Joel Greenblatt's Forgotten Original Magic Formula

By Evan Bleker :

Did you know that long before Magic Formula investing went mainstream, Joel Greenblatt was developing and testing an even more powerful investment technique?

Joel Greenblatt: A Beautiful (Investment) Mind

Joel Greenblatt has one of the best records on Wall Street. Aside from being an adjunct professor at Columbia University Graduate School of Business, he's also well entrenched in the Hedge Fund industry through his management of Gotham Capital. From 1985 to 2005, Greenblatt is reported to have racked up an even better record than Warren Buffett did during his partnership days, earning 48.5% compounded over 10 years through a combination of special situation and deep value investing.

Actually, Greenblatt is one of the inspirational figures that have driven many Net Net Hunter readers to request free net net stock ideas .

If you've heard about Joel Greenblatt, it's probably due to his widely read book, " The Little Book That Beats the Market ". In it, Greenblatt makes the case for a formula that investors can use to achieve superior results over the long run. Essentially, the formula looks for businesses with a large earnings yield and a high return on capital. The premise is that, over the long run, stocks of firms that are both cheap and good would vastly outperform the stocks of firms that are just cheap - and it definitely seems to have worked. As Greenblatt showed in his book, from 1988 to 2009 the magic formula produced a CAGR of 23.8% versus a 9.6% CAGR for the S&P 500.

The Original Magic Formula

Joel Greenblatt's love for the cheap stocks of good companies started long before he developed his latest Magic Formula, however.

It's probably no surprise that the backbone of Joel Greenblatt's original magic formula rested on Benjamin Graham's net net stocks strategy. Greenblatt had been following Graham for years, carefully studying the principles and philosophies of the Dean of Wall Street, and was deeply impressed by, in his words, "the dramatic success of companies that the market priced below their value in liquidation…".

Benjamin Graham's own NCAV stocks strategy was to buy a diversified list of net net stocks that were trading at least 1/3rd below their net current asset value. Graham screened out stocks that failed to show a decent past record and those that were losing money. By putting together a diversified list, Graham hoped to take advantage of the population returns and ride the fantastic statistical record of net net stocks as a group.

In 1981, at just 24 years old, Joel Greenblatt teamed up with Richard Pzena (a great value investor in his own right), and Bruce Newberg to test their own version of Graham's NCAV investing approach. The result was a fantastic research paper called, "How the Small Investor Can Beat the Market: By Buying Stocks That Are Selling Below Their Liquidation Value" (The Journal of Portfolio Management 1981.7.4:48-52).

In his paper, Joel Greenblatt wondered what would happen if he carved up the world of net net stocks even further, eliminating a lot of the terrible firms from contention. To do this he turned to one of the most widely recognized valuation metric in finance: the PE ratio.

Using both Graham's net current asset value and value investing's classic PE ratio, he put together 4 different portfolios and compared those portfolios from 1972 to 1978 against the OTC and Value Line's own value index. According to Joel Greenblatt, this period was characterized by an extreme amount of volatility which made for a much more robust test.

To select the stocks, Greenblatt only looked at firms in the Standard and Poor's Stock Guide with market caps of over $3 million and names that started with either an A or a B. He then drew net net stocks from the roughly 750 candidates left in order to put together his model portfolios.

Purchases were made based on the above criteria. Stocks were sold after a 100% gain or two years had passed, whichever resulted first. The portfolios themselves were equal weighted, so the actual yearly returns of each portfolio were just the average returns of the stocks within each portfolio.

All of the portfolios beat the indexes by a wide margin. By combining liquidation value with smaller PE ratios, however, results exploded.

Take a look at portfolio #4. The CAGR of portfolio #4, Greenblatt's original Magic Formula, blew the market away. While the OTC CAGR totaled just 1.3% for the 6-year period, and the Value Line index came to a slight loss, Joel Greenblatt's original Magic Formula was up over 42% compounded per year from August 1973 to April 1978!

Greenblatt et al even included returns after commissions and taxes, for those of you who aren't holding your portfolio in a tax free retirement account for some strange reason. Re-examined, Greenblatt's best performing portfolio still destroyed the market, up over 29% versus flat returns for the indexers.

(As an aside: if you're stuck holding your funds outside a tax shelter, for some reason, you can boost the tax efficiency of your portfolio by just holding your stocks for longer. This becomes a lot more viable if you're investing in the highest quality net nets.)

Three Major Takeaways from Joel Greenblatt's Study

It's hard to argue with returns like that.

Still, the more observant of you might have noticed a few potential flaws with the study and results.

At first glance, it definitely appears that you can't hold a large number of stocks in a portfolio using Joel Greenblatt's criteria. If you look to the right of each period's return, you'll see exactly how many stocks he held. In fact, Greenblatt et al were out of the market entirely for a lot of 1972 and 1973.

I don't think this is a crippling flaw to his strategy at all, however.

It's important to realize that Benjamin Graham's obsession with wide diversification isn't really necessary. In Joel Greenblatt's first book, " You can Be a Stock Market Genius ," he argues that you need fewer than 10 stocks to eliminate most of the systemic risk that you face while investing in stocks. Ultimately, you don't need 30 or 100 different stocks to diversify away most of your risk. You can do it with ten.

You can even leverage Greenblatt's original Magic Formula, portfolio #4, while maintaining a fully stocked portfolio during the upper reaches of a bull market. The trick is to put together a portfolio of other net net stocks and then replace the weakest links in your portfolio with a portfolio #4 type net net when it comes available. Doing so would allow you to leverage the returns of NCAV stocks as a group while still employing Greenblatt's original magic formula when available.

You could even choose the best net net stocks that don't meet Greenblatt's criteria by focusing on NCAV stocks that are trading at an incredibly cheap price to NCAV, have no debt, are growing NCAV per share, are buying back stock, or which have insiders who are buying big blocks of shares, themselves.

Lastly, remember that Joel Greenblatt et al only looked at companies with names that began with the letters A or B. That inevitably eliminated most net nets from contention. In my own experience, there are a lot of net net stocks available for smart investors willing to invest internationally. I send many of these stocks out to those who requested free net net stock ideas .

The second takeaway is that both quality and price have a major impact on returns. Looking at the results, when holding PE requirements constant, the cheaper portfolios in terms of price to NCAV outperformed the more expensive portfolios. Likewise, when holding price to NCAV requirements constant, the portfolios that demanded more earnings for the price paid outperformed their peers. By combining both value and quality, as Greenblatt did in portfolio #4, an investor can do very well in the stock market.

Finally, it's fairly clear that Joel Greenblatt's original Magic Formula, and NCAV stocks in general, trumps Greenblatt's contemporary Magic Formula. Sure, the Magic Formula that Greenblatt champions in his latest book is a good investment strategy, on the whole, but it just doesn't live up to his original Magic Formula. While his contemporary Magic Formula was reported to return just north of 23% per year vs. the S&P 500′s 9.6% return, Greenblatt's original Magic Formula spanked that return - and did so during a flat market, as well!

How I'm Leveraging Greenblatt's Original Magic Formula

As you can see, Greenblatt's original Magic Formula is magical indeed.

His study has had a huge impact on my own selection criteria. When selecting stocks, I look for firms that have a deep discount to NCAV but still focus on high quality situations. For example, I currently own two deeply discounted stocks based on NCAV and earnings: one trading at just over 5x earnings and just over 40% of NCAV; the other offering a PE of 6 and trading at 68% of NCAV. Joel Greenblatt would be proud.

The biggest challenge to earning 25-35% annual returns is not the actual investing - it's finding the investment opportunities. Right now Net Net Hunter has over 400 net net stocks in 5 countries and shortlists of the best possible investments opportunities in each country. Make the most of your time by quickly finding the best net net stocks available.
