Nvidia (NVDA) - despite the great FQ4 report, the graphics chip stock ended down nearly $3 in Friday's trading. As previously warned, $120 was set to be strong resistance. Nvidia blew away analyst estimates for the year-end quarter, but the tech giant only earned $1.13 per share. The stock is in no mans land at $113. Twilio (TWLO) - on top of the issue with a stretched valuation, the cloud communications company saw the final 31 million shares reach lockup expiration. One shouldn't expect insiders to rush out and sell the stock in the low $30s, but such lockups tend to add pressure to a richly valued stock like Twilio. Yelp (YELP) - the stock plunged nearly 14% on Friday as the market over reacted to some tepid guidance. As I highlighted last week, Yelp is a compelling stock for multiple reasons. Use the dip as an opportunity to own this leader in local ads. Zynga (ZNGA) - as predicted after the earnings, the mobile-game developer would see investors rush in around $2.40. The results weren't that exciting, but the stock traded towards $2.50 for that specific reason. Not sure Zynga is worth chasing here when one should've bought at the lows on Friday. Acacia Communications (ACIA) - downtrend still remains intact despite competitors reporting good results. Avoid the stock.
