Over the course of time, investors will acquire the same average gains before costs regardless of whether their portfolios are actively or passively managed. These gains are most likely going to be equal to the market average between investment strategies. This means that by limiting the costs of managers making trades and buying securities, a person using the passive management method will ultimately show higher gains. Basically, if one buys a boat that requires no maintenance, it is more profitable than a boat that needs maintenance every year, regardless of how fast it goes.
Due to the overall movement of the market, keeping a stable strategy has many favorable factors. Many investors believe that no particular strategy will result in any higher gains than others. In this way, keeping a stable strategy of passive management is relatively the same as any other methodology.
