Palantir Technologies- My first mistake

Hey all first post on here,

I started investing 4 years ago when I turned 18 and PLTR was one of the first stocks I researched and decided to invest in. I was very confident in the company doing well but was down for a year and then once I was up 30 percent I sold. I would be up nearly 250 percent now and who knows where it will be in the future. I held one share for fun but it won’t do me much lol. Going to regret this one for awhile, but learned my lesson about putting money in and leaving it long term.

Moral of the story, stay confident and hold long term.
