Before Covid I thought I'd chuck a few hundred dollars into a trading app to understand that 'game' a little bit better. I chose a few companies I knew from work and some biotechs that had fun ticker names. One company had 'mRNA' which I thought was funny, so I bought 50 dollars of stock.

Turns out mRNA stands for Moderna and I wish I put in more than 50 dollars as it went from ~$19 to almost ~$400 per share.

I, too, wish I’d put more into my winners, and less into the losers. But what I really wish is to figure out which is which before I lay money down. :-)
