Last week brought even more stock market weakness and volatility as the selloff became self-perpetuating, with nobody mid-day on Wednesday wanting to be the last guy left holding equities. Hedge funds and other weak holders exacerbated the situation.

Have you noticed that there hasn’t been much new to say about the stock market and its drivers lately? Bears are weary from calling tops that don’t follow through, and bulls are hesitant to inject more cash until they have a more inspiring catalyst. So, we’re pretty much left to wonder whether the overworked mantra “Sell in May and go away” will be a self-fulfilling prophecy…or a contrarian catalyst for the bulls to get busy again.

U.S. stocks are raring to rally. Earnings reports have been quite good. Consumers are spending despite stubbornly high unemployment. Interest rates are at rock bottom, which is good for borrowing and also makes stock yields relatively attractive. So what’s the problem? Oh, just the usual—fear of a European debt meltdown triggering a global recession.

In the last week, two of Sabrient's favored stocks have rewarded investors with big moves.

On the long side, HealthSpring Inc. (HS) is up 96%  this year. While previously gaining over 75% before the market correction in August, HS rose over 30% on Monday on news that CIGNA would buy them for 3.8 Billion to expand their Medicare business. HS is part of the Sabrient Baker's Dozen, a batch 13 stocks that we expect to perform well for the entire year starting January 1, 2011.

Green Mountain Coffee Roasters (GMCR) has been under investigation for nearly a year  due its "questionable" accounting practices and frequent restatements. Anthony H. Catanach Jr. & J. Edward Ketz, two college professors, think GMCR will be going down hard before too long. Their verdict:

Does anyone at Green Mountain Coffee Roasters (NASDAQ: GMCR) know math or accounting? Seriously, does anyone in their accounting department know how to count the beans?
