The following is a list of breakout stocks, based on moving average trends. For this article, we tracked down stocks that have recently seen the 50-day simple moving average (SMA50) move above the 200-day moving average (SMA200)--a bullish technical signal called the "Golden Cross."

These stocks are also undervalued when comparing current price to the fair value price, calculated by the Graham Number equation.

The Graham Number is named after a formula developed by legendary value investor Benjamin Graham. It is the maximum price an investor should pay for a stock, and it is derived using only two data points: current earnings per share and current book value per share.

Here's the formula:

The Graham Number = Fair Value of a Stock = Square Root of (22.5) x (Earnings per Share) x (Book Value per Share).

The math of the Graham number is relatively straightforward. It is predicated on the 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.

From that, 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, from which the equation was created.

Do you think these companies are undervalued? Are these names positioned to move upward? You be the judge.
