Stocks to watch on Tuesday: LendingClub (LC) - the online lending platform remains an incredible bargain at $3.50. Loan originations remain strong while the stock trades near all-time lows. The market is vastly missing the growth story here. Advanced Micro Devices (AMD) - holding $19 was a bullish signal. The stock continues to quickly turn as 7nm chips are on the way making for a secular play while the bears are too focused on the cyclical semi sector. Fitbit (FIT) - holding $5.75 on a 600 point down market is another sign that the turn has occurred at Fitbit. Load up while the $5s last. Disclosure: Long LC, FIT
