Twilio (TWLO) plunged yesterday on news that Amazon (AMZN) was working on a two-way messaging service. The cloud communications stock surged today on the following tweet from the CEO. https://twitter.com/jeffiel/status/912775401084035072!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");My hope yesterday was that Twilio would dip back to $25 based on the Amazon worries, but the CEO quickly squashed those fears with news that Twilio is powering the new Pinpoint service. The stock appears destined for a test of strong resistance at $35. Investors though shouldn't buy the stock if one can't handle the risk and sudden drop in the stock if Amazon officially becomes a competitor and not a partner. More thesis on the stock really hasn't changed: Twilio: Back On TrackDisclosure: No position
