Not quite, but a heck of a lot poorer than if I'd never heard of Tesla! It has been a salutary lesson in the madness of markets and brought home once again the truth of Keynes' maxim, which I quoted in my original piece, about markets staying irrational for longer than you can stay solvent.
Amazingly, I still think my original analysis wasn't far out and that the share price will eventually tank. Even if if falls to less than $100, equivalent to $500 in 'old money', I will still consider it expensive. That's less than a sixth of its current market price.
After taking the drubbing towards the end of last year and early this year, which has been well documented on these pages, I closed all my short positions in the stock and took some time to lick my wounds.
I eventually went back in, but more cautiously, adding stop losses at a number of price points for different tranches, so that, no matter what happened to the price, I wouldn't lose more than I had budgeted. Of course, the almost continuous increases in the share price through 2020 have meant that I incurred further losses, but nothing I wasn't prepared for. I've also had to start new 'budgets' a number of times, but all in a controlled fashion.
I am still short on Tesla. There is enough money in the account to cover losses up to the stepped stop loss points, so I won't have to put my hand in my pocket again, even if the price keeps rising forever. On the other hand, if the price falls, the plan is to move the stop loss points lower, and add to my short position, while staying within my budget at all times.
