Usually i´m not a fan of buying simple call options but sometimes there are huge gains possible. On 03.31.2021 NVDA crossed it´s 50 EMA, so you could see it as a possible buy setup. At this time the 600 call (OTM) which expires today (04.16.2021) had a price of $1.29. Yesterday it closed at $44.35!!! A $ 500 investment would have brought in $17,189. Oh man, i was such a sleepy guy!
