I would like more oversight here but I don't know if these are great examples. I do (without evidence) believe a lot of these people use insider information.
Pelosi's husband has been very bullish for a long time on Tesla, Apple & tech in general I do believe.
Gottheimer did what I think is a Bull Call spread which means in February, after a crazy run up in market prices in January, he bet that MSFT would go up a little more but would eventually come back down or at least trade sideways & not go over $160 by 6/18. If he sold his ITM calls before March or in early March, he probably did good. If he held on to them until closer to the 19th, he might have got crushed. This doesn't say when he sold. A lot of people argued stocks were overbought after January. Also, if he owns a large share of MSFT it's common to sell calls when you want to keep your shares but think the price is at the top or there is a lot of volatility that will soon go away. It's a way to earn some income without selling.
- None of this is financial advice & I'm fairly ignorant on this topic.
