Look at Pelosi's option play. Right now at the time I am typing this, 9/16 2000C on GOOGL cost $97430/contract. GOOGL is trading at 2933. The intrinsic value of the contract is $2933 (current share price) - 2000 (strike price) = $933 x 100 = $93k. Look at the price of the option - it is $97430, meaning time value is only worth about $4k while the intrinsic value dominates the price of the option (it is worth $93k). Pelosi doesn't give a shit about theta, IV, etc. etc., she's playing the intrinsic value of the options contract.
Delta on her 9/16 2000C is about 0.9, meaning for every $1 GOOGL goes up, she makes 0.9 x 100 x 10 (because she bought 10 contracts) = $900. How many shares of GOOGL would I have to go out and buy right now if I wanted to make $900 every time GOOGL went up $1? Obviously I'd have to buy 900 shares of GOOGL, which would cost 900 x 2933 = $2.6M right now. How much did Pelosi pay for her options contracts? $990,000. See the difference? Pelosi gets to basically own the stock of GOOGL for only $990,000 using deep ITM options versus having to buy $2.6M worth of stock to make the same amount of profit per $1 move of GOOGL. It's because options are levered plays. Pelosi only gives a shit about the intrinsic value of the options contracts and isn't a degenerate ape WSB gambler who wants to play the time value premium changes for OTM options. You can use options for a lot more things than just gambling on time value....deep ITM options are like owning the stock for a fraction of the price of actually going out and buying the stock.
