Actively managed mutual funds mostly outperform those that merely track an index true or false
sukhopar [10]

The statement is false. Unfortunately, evidence that actively managed funds can consistently outperform their relevant index is difficult to find. It's even more challenging for an individual investor to identify which actively managed fund will outperform the index in a given year.

Yes, you may be able to beat the market, but with investment fees, taxes, and human emotion working against you, you're more likely to do so through luck than skill. If you can merely match the S&P 500, minus a small fee, you'll be doing better than most investors.

Mutual funds are actively managed by an investment professional, while index funds are more passive. Mutual funds come with much higher fees than index funds, which can cut into your potential gains.
