This 2010 release is an update of Greenblatt's original The Little Book That Beats the Market, a New York Times Bestseller. In his book, Greenblatt, a Wharton School graduate and highly successful hedge fund manager, presents a clear and simple investment strategy that any investor can follow. He humorously presents his “Magic Formula” in all its glory in under 150 simple to read pages.
Greenblatt is a value investor, and he mentions Benjamin Graham, the father of value investing, a number of times in this book. Graham had something of a “Magic Formula” himself, but as Greenblatt points out, Graham's formula does not work very well in the our time as it would be rare for any current stock to meet Graham's strict criteria.

The “Magic Formula” balances these two values to produce a list of the best stocks to buy. A stock, no matter how cheap based on Earnings Yield would not make the list if it is a bad business based on Return on Capital. Greenblatt also provides a website which will show you a list of stocks so you don't even have to do any of the leg work yourself.
The formula calls for you to maintain 20 – 30 holdings, and sell each holding after one year. The number of holdings will help minimize the damage to your return one or two bad apples can cause. The one year holding period recommendation is so you do not hold a stock for too short or too long to take advantage of the gains. Greenblatt points out that you must stick to the
