I am a typical J type investor. First , I do have my own excel sheet. Second, I planned my investment years ago. recently two times investment, first investment, covid-19 breakout, oil prices dived, I invested oil company stocks, Covid-19 vaccine implemented in major economic country, I took the profits. Second investment, current one is ongoing, dividend stocks. simple theory, dividend stocks have common property likey bond, interest go up, dividend stocks prices go down. I can't predict the future, keep adding a position at a lower price. it is not bad, interest rate are at peaks now, and my assets are at breakeven, I am waiting and paid by dividend income. Investors must have their own idea and strategies, don't change plans randomly.
