Social media giant Facebook (FB) is hovering in a buy area as it trades in a narrow price range. The stock got a scare Sept. 15, when it dropped nearly 4% in heavy volume and fell below its 76.09 flat-base buy point. But Facebook got support at its 50-day moving average the next day and retook the buy point soon after. The stock is near a record high. But buying now is riskier with the market’s uptrend under pressure.
