To be honest, Michael Burry is NOT a big name investor. He just happens to be a guy that made a name of himself being far too early (which means he was wrong) in his short bets long before the 08 financial crisis.
"But your lifetime savings are like $200,000 and you place them all on selling naked puts and the stock value drops 50% overnight. You just lost HALF OF YOUR LIFE SAVINGS in a single blow."
True if you do it with an individual stock. I rather own an ETF if things blows up. Then I'll be forced...
When an OTM put pays that much of a premium, it usually means the underlying stock is highly volatile. You will probably get assigned. So be prepared to own the stock going forward, if you must do the trade. Otherwise, don't do it.
Yes he's making money (so long as we are in a bull market), but much less had he simply went LONG and HOLD. Investors/traders who uses this short PUT writing/selling strategy are the ones who likes to sleep well at night. ;-)
