Apple ( AAPL ) shares closed below their 200-day moving average for the first time since September 2013 last week. The move below $120 officially put shares in "correction" territory, and the bulls will need to recover that level this week. But Apple wasn't the only high-profile name to see its shares take on additional turbulence. Twitter ( TWTR ) touched fresh 52-week lows following Friday's drop to $26.87. TWTR shares look "cheap" at current levels, but Twitter has far more issues then a sagging stock price. TWTR is trading within $1 of Wall Street's initial public offering (IPO) price of $26 a share from November 2013. While I mentioned that TWTR shares look cheap, it wouldn't surprise me to see them get even cheaper. There is no technical support at current levels, and the recent slide to fresh all-time lows is not an encouraging sign. Twitter's market cap is a little over $18 billion. Takeover rumors for the company have picked up in recent weeks, but, without a CEO, a deal is hard to do.
