MARKET CAP: PASS

The first requirement of the Cornerstone Growth Strategy is that the company has a market capitalization of at least $150 million. This will screen out the companies that are too illiquid for most investors, but still include a small growth company. THO, with a market cap of $5,541 million, passes this criterion.

EARNINGS PER SHARE PERSISTENCE: PASS

The Cornerstone Growth methodology looks for companies that show persistent earnings growth without regard to magnitude. To fulfill this requirement, a company's earnings must increase each year for a five year period. THO, whose annual EPS before extraordinary items for the last 5 years (from earliest to the most recent fiscal year) were 2.86, 3.29, 3.79, 4.91 and 7.09, passes this test.

PRICE/SALES RATIO: PASS

The Price/Sales ratio should be below 1.5. This value criterion, coupled with the growth criterion, identify growth stocks that are still cheap to buy. THO's Price/Sales ratio of 0.68, based on trailing 12 month sales, passes this criterion.

RELATIVE STRENGTH: PASS

The final criterion for the Cornerstone Growth Strategy requires that the Relative Strength of the company be among the top 50 of the stocks screened using the previous criterion. This gives you the opportunity to buy the growth stocks you are searching for just as the market is embracing them. THO, whose relative strength is 59, is in the top 50 and would pass this last criterion.
