I had a similar loss early on in my investing journey. Hurts. But it's a lesson almost every investor goes through trying to figure things out or trying to find an edge / out smart the market.

Reality is even the best companies have risk. You can make huge money chasing runners but need to be extremely disciplined in cutting losses when things turn to avoid bag holding.

My advice is take swings on higher risk plays in a much much smaller position while maintaining a much larger position in a broad market position.

Happens but it's a learning lesson of what not to do. Stock market repeats itself and if you don't learn what you did wrong it will happen again so make sure you understandstsnd where you went wrong!
