Stocks to watch on Tuesday: Snap (SNAP) - Citron Research placed a $17 target on the stock. Watch for Snap to close the gap to $14 before shorting again. The social messaging site has a long way to go before becoming a long. Twitter (TWTR) - stock trades at nearly $40 following entry into the S&P 500 index. Might be good time to lighten up on a position before an entry into the index on June 7. Twitter is no longer cheap, but the long term upside is enormous. Fitbit (FIT) - the 1 million Versa smartwatches shipped is a very positive sign that the fitness tracking company is onto another hit. The $200 price point provides the separation with the Apple Watch needed to compete with the full solution from the tech giant. The stock is relatively cheap even at $6.25 and a market cap of only $1.5 billion.
