Lululemon's stock tumbled nearly 19% after the company annnounced its CEO will be stepping down.
Investors swooped in, hoping to pocket quick gains if they recover this week.
First Solar, lululemon and Facebook -- all had harsh news to contend with during the week, sending their stocks spiraling down. The low prices attracted investors, making them last week's most-bought stocks, according to data from online broker TD Ameritrade.
"People are playing them not necessarily as a long-term holding, but for a bounce," said JJ Kinahan, chief derivatives strategist at TD Ameritrade. "They'll get the bounce early next week."
The trigger: The solar panel maker's shares sunk almost 16% last week, after First Solar ( said it planned to sell 8.5 million shares in a ) secondary offering.
The secondary offering should have been a positive for investors: The company swung a profit in the first quarter, and the stock has rallied nearly 70% this year to $44.71. These are prime conditions under which the company should raise more capital.
But a company's stock often falls after a second offering because more shares mean that ownership gets watered down.
The trigger: The trendy yoga-wear maker announced last Monday that CEO Christine Day is stepping down. The move followed a controversy earlier in the year in which lululemon ( was forced to pull certain yoga pants from stores, because they were see-through. )
The stock was down nearly 19% for the week at $66.15.
The trigger: The social media giant held its first meeting for shareholders on Tuesday. Chief executive Mark Zuckerberg faced a barrage of angry questions from investors, many of whom aren't happy with the performance of the company since it went public last year. Facebook's ( stock, at $23.63, is trading nearly 40% below the price of last year's initial public offering. )
