If you have an investment vision, you can still study it. There are many fund stocks that can generate some income. But many people have no investment vision. They don't know anything about finance, so they choose to join the stock market. This is not a happy ending. So many people also say that stock trading is just like gambling. But in fact, these two things cannot be compared.
But if you want to invest, you still need to learn some financial knowledge in order to understand it in the stock market. Otherwise, it is no different from gambling. Because you certainly don't know whether to win or lose when you are studying for a PhD, you certainly don't know whether it is possible to make a profit if you join the stock market without any financial knowledge. It's more like gambling at this time. A lot of people are counting on getting rich overnight and counting on Qian Shengqian. So this mentality is similar to gambling. But investment is a very rational thing. If you can't have a very rational attitude, you can't learn to invest, which will cost you everything.
There are many people who are irrational. They will put all their wealth into the stock market. I don't think this practice is recommended, because at least they should leave some money for crossing the river, or leave a back road for themselves. If you devote yourself to the stock market and have a slightly different investment vision, you may lose everything. Therefore, I think it is better to leave a way out for myself and then invest with a small amount of money, which is a more rational attitude.
