TWTR executed a near-perfect V-shape gain on the 1D after rumors came out of a possible subscriber-based service. HOD was perfectly lined up with a previous high indicating some strong resistance at the 37 level. For more technical buy-and-hold investors the MACD just crossed up the Signal, and the RSI is still in a safe range. TWTR may still have more room to run as it tests 37 and potential breaks.
