Stocks to watch on Tuesday:GrubHub (GRUB) - the online food ordering and delivery stock traded below $20 in 2016 and now trades at $56. Have to agree with CS, the stock appears overheated trading at 40x forward EPS estimates.Synergy Pharma (SGYP) - the biotech had a nice bounce off the lows. With a reasonable path to positive cash flows, Synergy is a solid buy with a market cap only slightly above $600 million. Himax Tech (HIMX) - with the 11% bounce today, Himax Tech appears headed to new highs. Any time a stock shakes off a negative analyst call, the stock is likely headed much higher. LendingClub (LC) - the fintech remains a big buy above $6, but hopefully investors used the recommended idea to buy LendingClub below $6 last week. Chipotle Mexican Grill (CMG) - on a very bullish day in the markets, the stock only jumped 5 points. A good sign that Chipotle will head below $300 on the next down day.
