First, let's talk about the operation. The so-called Strangle strategy involves simultaneously buying/selling calls and puts with the same expiration date but different strike prices to go long or short on volatility for profit. Let's take Short Strangle as an example. Currently, NVIDIA's stock price is around $220. Assuming we believe that after the earnings report, the stock price will fluctuate by about 10% up or down, meaning between $200 and $240, we can then sell the $200 put while also selling the $240 call.
