Actually, here's what happened to me: I had 5 contracts of TSLA200117C250. (Calls with a $250 strike price, expiring on the 17th of this month.) I bought them for $18.10, spending $9,050 using a $10,000 account I had just opened. I sold them before the last earnings and bought puts, because I expected a brief run down. The puts lost me around $7,000 that evening, but worse: it also lost me around $19,000 which I would have had in my account that evening if I had kept the calls. (Essentially it would have tripled my account overnight.)
But it's worse than that, because those same calls... The ones I had bought for $9,050 (at $18.10) actually sold for $123,000 (at $246) a couple days ago... That would have been $113,950 profit, from a $10K account, in only 2-1/2 months. (And since I believe it'll go over $500 before they expire and they're in the money, it would be even better at expiration.)
For some reason I still keep looking at the price of "the calls I should have held"... Because I guess I enjoy self-torture. Luckily they expire in 8 days so I will no longer be able to check.
The sting of this experience has made me more of a "holder" than a "trader". I'm holding calls again now, trying to get back my original $10,000.
The simple lesson here is that when you gamble you might win and you might lose. I bought my TSLA shares for around $35 or $40 after I got my Roadster, because I loved the car so much. I also bought some shares in Solar City when it went public because I liked what they were doing. And I bought some solar bonds so that somebody who didn't have the capital could get solar panels. Then those Solar City shares become an odd number of TSLA so I had more of those. The result is that if I sold my TSLA shares now I'd make a bundle. But I don't need the cash and I like being a part owner of Tesla.
My regret is that I didn't put everything I had into TSLA back when I bought those first shares. I could have afforded a house on a cliff overlooking the ocean in Makena instead of a house without an ocean view in North Kihei. I could have a chauffeur and a chef and maybe even a bevy of bathing beauties. But the problem is that when TSLA was $40/share it was uncertain whether or not the company would stay afloat. And I'm not a risk-taker. Day-trading, whether it's shorts, longs, puts, calls, margins, derivatives, or commodities, is gambling, just like Vegas, but without the free drinks.
