Last night was a quite severe day of decline. Overall declined, but especially $Applovin (APP.US)$ was the most prominent in the collapse. It was falling after hours due to not being included in the S&P 500, and when the market opened, it fell even further. I had just closed my positions last Friday, so it resulted in quite a painful damage.
Since all the stocks I owned were declining and suffered a painful loss on the app, I reduced the positions of all stocks to less than half as a way to brake once. With this, the position size has become half of the funds. $Tesla (TSLA.US)$ Since it didn't drop at all, it might have been good not to touch it.
It may seem like another small trade, but due to significant agitation in yesterday's market, I had to adjust my position. That's who I am. I hit a wall while driving a car, and it's like imagining hitting the foundation brake because it would be strange to continue driving like that. Some people may not be affected by yesterday's crash and those people may do well with holding or buying more...
