The Dow ended the week back above 20,000 and the market faces a week with a blitz of earnings. Below are some of the key stocks for tomorrow and the week ahead:Twillio (TWLO) - as predicted, the stock saw a bottom around $27.50. Twillio is now over $31 with earnings on Tuesday AMC. The cloud communications provider will need a stellar earnings report to justify any rally beyond $35. Remember, don't get caught up in where the stock came from at $70. Most analysts see a true valuation around $35 and the stock quickly gets expensive at that level. Twitter (TWTR) - reports earnings BMO on Thursday. Is it possible that the social media company reports faster user growth than Snap (SNAP)? The market still sees Twitter mostly in decline so a surprising bump in users good light a fire underneath the stock. Nvidia (NVDA) - the graphics chip company reports AMC on Thursday. Watch for the stock to rally into the report and sell off even on good news. $120 is crucial and could signal a double top so be careful. Glu Mobile (GLUU) - stock ended the week at multi-month highs and above the 200ema on very high volumes. Follow up gains this week could signal a significant shift in investor sentiment. Is it possible that Tencent (TCEHY) is on the prowl to buy the remaining shares. Under Armour (UA)(UAA) - like as a value play at these levels and a quick dead cat bounce at the very least. The stock had a small reversal on Friday, but is due for a bigger bounce following the three days of beatings last week.
