When I lived in HK I could make $300 to $1000 a day doing day trades of the HS Index of penny stocks. I had a spread sheet with lows and highs and volume of about 30 companies with stock prices of about fifty US cents. When one hit a low I’d buy it. Often times buying 10K shares of that stock would cause it to go up a penny or two. I’d sell the stock I’d just bought the previous hour at a profit. Hong Kong of course has no capital gains tax so it was easier to do there.
Does that make me a bad person?
No, but the short sighted trading has led to the demise of long term wisdom in companies.
