Weird options scenario
So I am just a newbie in investing, recently came across that my friend lost quite a lot of money on options. He bought a 325 Put option for NFLX, expiring 25/Jan. With the anticipation that NFLX would fall on earnings, indeed it fell 5% today, but he lost 50%. The purchase price was 6.8$ the day before, it went to 3.2$ after the stock fell, losing half in price. Isn't the Put suppose to make him more money when the price is going down?
