Stocks to watch on Tuesday:Twitter (TWTR) - the stock soared 11% on a JPMorgan upgrade. At $24.68, Twitter is at new 52-week highs and in range of taking out the 2016 highs. Too late to load up on the stock now, but Twitter goes higher. Glu Mobile (GLUU) - the stock dipped 9% as the initial downloads of TSL disappoints the market. The high 4.9 ratings suggests the app has a long tail with Glu Mobile no longer focusing on initial downloads in favor of a slow build up. The stock doesn't even need success from Taylor Swift making the dip a buying opportunity.

Citron went short but Riot still soared today so good luck to anybody investing here. https://twitter.com/CitronResearch/status/942838933490098176!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");Click on the Sign in/Sign up button in the top right corner to join for free to comment on your stock moves for tomorrow.
