2015 $200. I think I saw that post as well. I faintly remember that the premium of those far otm options didn't reflect the volatility of the stock and the stock was hovering around $100 at the time. The premiums were like $10 or something. I suspect the person and his brother were experienced options traders though.
Someone could have bought just a few 35 or 40 strike LEAPs over a year ago(which I know many people were dong with TSLA), then at the start of the short squeeze about a year ago converted them all to a lot of cheap 6-month out 75 call options and made a fortune just from those two option trades alone. I know someone who made about a 10,000% return on their 4k IRA acct from doing this trade-up, it's a gamble but can pay off. They also say they bought a bunch of Jan 2016 250 LEAPs for about $15 each in Nov.
