NEW YORK (TheStreet) -- Profiling companies before they report quarterly earnings has become more difficult following Federal Reserve Chairwoman Janet Yellen's comments on Tuesday that valuations on small-cap, social-media and biotech stocks may be stretched.

Most of the nine stocks profiled today have been volatile this year. The stocks with the biggest year-to-date gains in today's "crunching the numbers" tables are SanDisk (SNDK), with a gain of 50%; Baker Hughes (BHI), up 32%; and AutoNation (AN), up 22%.
The biggest loser year to date is Mattel (MAT), down 18%.
