If you like to profit from short squeezes, then this may be an interesting starting point for your own analysis.

To construct this list we looked for stocks with the following characteristics:

- Market cap above $300M

- Short Float above 15%

- Trading at a significant discount to the Graham Number

The Graham Number was considered to be the maximum price an investor should pay for a stock, according to the formula developed by Benjamin Graham. â€¨

It is calculated as follows:â€¨

Graham Number = Square Root of (22.5) x (Earnings per Share) x (Book Value per Share).â€¨â€¨

This equation is predicated on Grahamâ€™s belief that the price-to-earnings (P/EPS) ratio should be no more than 15, and the price-to-book value (P/BVPS) ratio should be no more than 1.5.â€¨â€¨

Therefore we only included companies that meet both of these criteria. As a result, the product of the two should not be more than 22.5. In other words, (P/EPS of 15) x (P/BVPS of 1.5) = 22.5.

We last wrote about this screen on April 14. On that day, the screen produced 8 companies. Since then, 5 out of 8 companies mentioned in that article have outperformed the S&P 500 index (a success rate of 62.5%). The screen averaged a price-weighted return of 3% vs. an index return of 2.1%. Click here to access a full breakdown of the screen's past performance.
