It has been nearly 3 years since the first case of COVID was discovered. What’s the biggest investing lesson you learned since then?

For me, one I can certainly say hit close to home for my investment strategy would be:

“Don’t chase gains without an exit plan”

Throughout the end of the bull run, there were many companies I bought into. Some good, and some bad, but the common theme was I didn’t have a plan for exiting the position.
Some of my picks worked out great – locking in gains on pandemic high-flyers and rotating into a broad market ETF or cash.

Many of my picks, and sadly too many, were once high-flyers that fell sharply and have yet to recover. I look back and it’s clear I should have sold several, especially the stocks boosted on investment euphoria and will likely never hit those highs again, and just as likely to never hit where I purchased. Many of these, I sold for big % losses, even after being up huge % at certain points in time.

All in all, I believe this lesson will make me a better investor for the future. I’d love to hear what other people have learned
