We'll start off with Groupon ( GRPN), a stock that's sort of exemplified Wall Street's disappointment with social media stocks. This Internet deal site went public in the biggest internet IPO since Google ( GOOG) back in November, pricing at $20 per share and falling like a rock ever since thanks to a combination of fundamental and technical factors. With especially ugly technicals shaping up right now, I'd suggest selling this stock. Groupon formed a bearish descending triangle pattern for most of the summer, bouncing in between a horizontal support level and downtrending resistance. Essentially, as shares volleyed between those two price levels, they were getting squeezed closer and closer to a breakdown below support. That breakdown happened at the start of July, spurring a sell signal in shares. >>2 Dividend Stocks to Sell for Profits And Groupon is showing no signs of finding bottom yet. Momentum, measured by 14-day RSI, has been in a solid downtrend since the start of 2012. Since RSI is a leading indicator of price, that means Groupon is in "sell mode" right now. I'd advise you do the same.
