It's for a project I have to do. What exactly can you learn from investing in the stock market?
I wrote how unpredictable it is and how hard it is to choose what stock to buy. You can never know for sure how the stock will do over an extended period of time.
There is a difference between what one can learn and what one does learn.
For me, I learned the hard way to cut ones losses rapidly, take a little of your profits off the table after a significant rise in stock prices, avoid high PE stocks like the plegue, avoid speculative stocks for the most part, avoid tech stocks also for the most part, put a fair portion of you money into index funds and mutual funds so you don't have to spend too much time baby sitting it, try not to have more than 30 stocks in your portfolio because it takes too much effort to keep track of them, keep weeding out the underpeformers and replacing them with stocks with greater potential. Alway have a healthy cash reserve and add to it as stock prices rise, so that when they drop you can take advantage of the situation.
