Sensing an opportunity that hasn't presented itself too many times since the Great Recession ended, investors pounced in February. 

TD Ameritrade clients appeared to use the pullback in stocks last month as a buying opportunity, the online brokerage house revealed Monday in its latest investor movement index summary. Unsurprisingly, investors gravitated to big-cap stocks with the most widely recognized names.

Stocks That Were Net Buys in February

General Electric (GE) - Get Report and Ford (F) - Get Report caught interest after shares hovered around multi-year lows, TD Ameritrade said. 

Action Alerts Plus holdings Apple (AAPL) - Get Report and Amazon (AMZN) - Get Report were bought after shares were sold despite solid fourth-quarter earnings from each.

Other popular names, according to TD Ameritrade, included Action Alerts Plus holding Nvidia (NVDA) - Get Report , Berkshire Hathaway (BRK.A) - Get Report and Netflix (NFLX) - Get Report . Netflix continues to be one of the hottest names in the market, and is up 50% year to date.
