Why do stock recommenders recommend stocks instead of buying them for profit?

The stock recommender has a glib tongue and looks like a stock god. Both disk analysis and basic theoretical knowledge are eloquent and well-founded. Since the analysis is so magical, why not stock yourself? The reason is simple, because they don't make money by trading stocks, or they are unwilling to take these risks. Some people may see that their technical analysis is so powerful that the quoted stocks are very logical. Is it impossible not to make money? The reason is also very simple, because they always take the past stock K line as an example. Can the past be used to predict the future? Obviously impossible. They also know the way of the stock market, know the risks of the market and see through the essence. After all, the referee used to be a shareholder. Analyzing stocks for others, teaching others to speculate in stocks and paying tuition fees are sure to make money, with little risk. However, in stock trading, they face the risk of losing half. The choice between the two is definitely to choose something with strong certainty and low risk. If you ask them to predict a stock, the accuracy is only half. The rise and fall of the stock market is not predicted, but driven by the funds of the day.
