I'm working on it, although I'm not sure I'll get there.
Even though the cheapest TSLA shares I ever bought were ~$180, and most of my shares were bought in the $200s and $300s, if I converted all my options to shares today, my cost basis on my entire TSLA stock position would be $31, and I think I'll get it down to $25-30 this year, if we get close to a post-split share price of $600.
It's unlikely there will be similar returns on TSLA options as we've seen over the past year ever again, so I'm not sure I'll ever get my cost basis down to the teens. Besides, there's a chance some option trades go wrong as well. But there should still be a solid decade of TSLA stock appreciation ahead of us, so maybe I'll get it down to the teens at some point through a few more options trades.
It'd be pretty cool to be able to get my cost basis down to IPO price, even though I was never able to buy during that period. It's not a goal per se, because it'd be a stupidly arbitrary goal to have, but if I do happen to get there, it'd be really cool
