Stocks to watch on Tuesday:Nvidia (NVDA) - after a big rally on Monday, the market cap is back to $100 billion. Last quarter revenues were only $2.2 billion. Do the math if you want to buy up here. Fitbit (FIT) - the wearable device stock is interesting at $5.50. The stock is mostly a call option on growth in the category and the potential for the smartwatch coming out before the holidays to surprise on the upside. Blue Apron (APRN) - Jana Partners taking a position after agitating Whole Foods Market (WFM) is noteworthy. Blue Apron is a similar call option on the meal-kit delivery market though one might one to wait for further shakeout in the stock and sector. Glu Mobile (GLUU) - 52 week highs aren't likely to hold this mobile-game developer from rallying further. Glu Mobile only trades at an EV of about 1.1x bookings. The stock only has a $400 million valuation and is now more consistently delivering growth without requiring new hit games that the market will continue to value.
