When the stock is going up, buying Calls seems easy. It doesn't matter if you are using Margin or not, if the stock crashes like it did from December 2018 to Jun 2019, and you are holding LEAPS, you will get killed. I lost $500,000 in Jan 2020 LEAPS with that drop. Luckily, I was smart AND LUCKY and sold stock around 200 and bought 2021 LEAPS which went up and erased my 2020 LEAPS losses. I can't tell you how painful that drop was. In the future, I will only buy LEAPS after a massive drop like we had 6 months ago. I will NEVER buy them again near an ATH. Sure, the stock might go up, but if macros turn against you, or Tesla has some setbacks, the SP will drop and you will lose big, because the time decay will start to kill you too. Just my 2 cents based on my agony this last year.
