$Tesla(TSLA.US) Wall Street's options harvesting machine has started. It's exactly the same as after NVIDIA's earnings report in the first half of the year. Before the earnings report, the implied volatility (IV) was extremely high, and after the report, the volatility inevitably collapsed. Then, they first controlled the market in the opposite direction, causing the volatility to shrink even more, buying back the sold calls cheaply to harvest the premiums. The next day, they sharply pulled the stock price in the opposite direction, buying back the sold puts at low prices to profit from the put premiums.
