Stock Market

I don't remember exactly, but there have been something like 10 ish bubbles since the crash of 1929 and within 3 mos? the market was at or above what it was before Buble bursts .
I had just begun actively trading for the dot com bubble .
What I learned from all, and my biggest mistake was buying penny stocks hoping for the moon, and being disappointed many times .
It used to be a staging line thrill to hit buy, then sell less than 5 mins later. I was a pesky "day trader" that caused the bubble to burst, lol
I learned to buy " blue chip" stocks, quality, earnings, huge value.
Apple, Amazon, Microsoft, Tesla, Boeing, Nvidia, Deere, ADM, Cat?, and select others, but there are a world of ETF (Electrically Traded Funds) now avail that have a buncha quality companies in one fund .
Arms funds, defence weapon funds, bank funds, these are how folks get quality dividend paying fund, you buy/sell on computer.
Buy a few bluechips, they increase, split, increase, split, apple split 7 for 1, my 15 became 95, they split x 2 twice, sold half. Playing with house money.
You should consider diversifying, holding CDs, bonds, gold, guns .
Always do your Due Diligence .
Any trades you enter is your decision, and your's alone .
Questions welcome, but I certainly don't know fk, as you all know . lol
Cheers
