I’ll tell you my dot com story. I bought the Juniper Networks IPO. It ran, split, ran, split, ran again. My 200 shares became 1200 shares worth just under 300k in 6 months!!. My goal was 325k to pay off my mortgage. The market dipped, no problem, it’s gonna come back. It dipped again, and again, and again. I finally sold for under 20k. Same thing in my kids 329 college funds. I had a goal for their college education which was far surpassed (AOL was a big holding) but greed hit and I didn’t sell. Why should I sell? Pundits said NASDAQ was gonna hit 10,000 and the Dow was gonna go to 50,000.
That was 21 years ago. Learned my lesson the hard way. Folks much smarter than me lost millions. I was fortunate compared to them.
