Stocks to buy after another tough week: Twitter (TWTR) - the big 25% gain didn't hold as the market lost 1,000 points and Citron cashed out. Remember though that Citron sold at $35 and Twitter now trades at $30 providing 15% upside from here just to hit their target. Yelp (YELP) - the consumer review site continues to generate 20% growth in key metrics and the stock trades at a very attractive valuation below $40. The market still doesn't value Yelp for the consistent local ad revenue growth. Synergy Pharma (SGYP) - the small biotech continues to hold near $2 despite the beatdown in the general market. Remains a reasonable place of own the risky stock. The best part about this group is that Q4 earnings or financing risks are out of the way for these stocks. Other interesting stocks like Under Armour (UA, UAA) haven't reported so being aggressive into earnings isn't warranted though one might want to start an initial position.
