我开仓了2手$MSFT 20240216 420.0 CALL$ ,财报前微软的隐含波动率达到了一年来的最高水平，正是赌财报的好机会，卖出一个行权价为420的call，再卖出一个行权价为390的put，构成一个宽度跨式期权。这是娱乐性质交易。Before the financial results release, Microsoft's IV reached the highest level in a years It is a good opportunity for betting on earnings to sell a call option with an exercise price of 420, and then sell a put option with an exercise price of 390, forming a width Straddle option. This trx is just for fun.
