Twilio (TWLO) - Get Twilio, Inc. Class A Report provides cloud communication platforms for voice and messaging applications. The stock has retraced nearly all of last year's powerful post-IPO high, but more recently has been forming a rounded base and is back above its 50-day moving average. This month the company reported stronger than expected fourth-quarter earnings. With a 33% short interest in the stock, covering of that short exposure could spark a powerful rally.

TheStreet Recommends

Shares jumped over 9% in Monday's session taking them back up to the December 2016 high and breaking above the upper band of a very constricted Bollinger band range. These periods of low volatility reflected in narrow bandwidth are often followed by periods of high volatility, and with the positive price and money flow indications and a large short interest, the path of least resistance is higher.

Twilio is a buy at its current level using a tight trailing percentage stop.
