The Biggest Earnings Winner Last Week

NEW YORK (TheStreet) -- Today we provide post-earnings profiles for the 21 companies we covered in four posts last week. We include two Crunch the Numbers tables designed to help investors navigate stock-specific share price volatility.

Our first table covers each stock's technicals including five important moving averages and updated readings on the 12x3x3 weekly slow stochastic for each stock.

The second table shows earnings and value levels at which to buy on weakness and risky levels at which to sell on strength.

We crunched the numbers to help you decide if and when to invest. See today's tables following these profiles.
