Mutual Funds are one of the most common ways to invest in equity and debt and a large mutual fund industry is involved in this endeavour.There are large number of high paying professions in Wall Street which depend on the mutual fund industry which include stock brokers and sales persons.However the amount of cost of mutual funds is not proportionate to the gains they give out.This is the reason that Exchange Traded Funds (ETFs) and passive funds which have lower expense ratios and expenses are gaining billions of dollars in money.The reason is that a large number of mutual funds regularly underperform the benchmarks.This has caused massive heartburn amongst investors who have to pay large amounts of fees for the services of the professional fund managers.This has been the trend historically and found amongst numerous countries as well.Besides the costs of the sales and distribution of these mutual fund with their hefty commissions also falls on the investor ultimately.However the prevailing custom of investing in mutual funds is not easily broken despite the underperformance of the mutual fund industry.Most of the advantages of mutual fund can now be found in ETFs which have much lower costs.They also remove the disadvantages such as the possibility of a bad mutual fund manager.
