Frequent trading does not necessarily lead to higher returns, but it does ensure income for these service providers. Generally speaking, the individuals that retail investors often encounter during the investment process will try their best to narrate stories of making significant profits in the short term. In reality, this is merely to earn certain fees akin to purchasing lottery tickets.
In contrast, long-term investing is often more rational but less attention-grabbing, so individual investors rarely hear promotions about long-term investing, which makes them prone to falling into the trap of frequent trading.
