Final answer:
It is true that most people lose money in the stock market, as the average investor and even professionals struggle to consistently outperform the market.
Step-by-step explanation:
According to the information provided, it is true that most people lose money in the stock market. The reference material suggests that the majority of financial investors cannot reliably outguess the market. There's a tendency for about half to two-thirds of mutual funds, which try to pick stocks that will perform above the market average, to perform worse than the market itself, highlighting the difficulty of stock selection. For the average investor, especially those who lack the time and resources of professionals, succeeding in this endeavor is even less likely. The material suggests a more guaranteed way to accumulate wealth is through ongoing education and starting to save early on rather than trying to beat the stock market.
The author states that the majority of financial investors do not outguess the market, and it is typically true that most mutual funds that attempt to pick stocks end up performing worse than the market average. Therefore, the statement that most people lose money in the stock market is true.
