1, TROV, it was pumped and dumped couple days ago, today after-hours , it released news that Blackrock bought their 5% shares.  It might bounce tomorrow morning due to news.

2, AMDA, it was pumped for 3 days, so that it could be dumped anytime soon.

3, I was also watching AMZN, I would like to short it if there is bad news from opec.
