It hasn’t all been a bed of roses for Twitter (TWTR) since its IPO in November 2013, but judging by its recent chart action, the Street seems optimistic that CEO Dick Costolo has the company on the right path after a recent management shakeup. After a nasty sell-off in 2014 that saw the microblog correct 60% off its high, Twitter is currently working on a cup-with-handle base with a 50.11 buy point.
