Is one more equity mutual fund helping or hurting your portfolio?

Equity mutual funds are the first choice of those who wish to build wealth over a long period. They have the advantage of professional management and exposure to a diversified list of stocks. But having money already, the question arises: do you add one more?

At first glance, it may appear that one additional fund will diversify and reduce risk. But beyond a certain point, too many equity funds dilute returns, make tracking more difficult, and impose unwanted duplication on your portfolio. Experts advise looking at your existing portfolio and investment objectives before jumping to a new fund.

Diversification vs duplication

Equity mutual funds themselves are diversified and carry 30 to 60 stocks from different industries. If you already have quite a few of them, say three or four, the marginal benefit of one additional fund is smaller. Funds mostly carry similar large-cap stocks such as Reliance, Infosys or HDFC Bank, so exposure won't grow much even after the addition of a new fund.

Rather than adding for the sake of diversification, it might be wiser to examine if your existing holdings do not already offer adequate exposure to various segments—large-cap, mid-cap, small-cap, or sectoral themes.

Portfolio clutter and monitoring challenges

Too much money makes your portfolio cumbersome. Monitoring performance, strategy of the fund manager, and rebalancing periodically becomes difficult when there are more schemes. It may even lead to unconscious overlap, where you end up purchasing the same basket of stocks through different schemes.

Experts advise you to have a maximum of four to six equity funds of different purposes. You can have, for example, one large-cap, one mid-cap, one flexi-cap, and one international fund. A new fund makes sense only if it has a different strategy or exposure that is missing in your current portfolio.

Aligning with financial goals

Prior to investing in another equity fund, investors must revisit their goals. If you're saving for retirement, children's education, or a home, consider whether your portfolio as it stands fits the time horizon and risk tolerance for each of these objectives. If the funds you already own are doing well and are adequately diversified, even more may not be necessary.

But if your risk tolerance has changed, or if there is a gap in your asset allocation—e.g., too little mid-caps or world equities—then it will be appropriate to add a fund.

Adding only another equity fund can be value-added only if it does something unique. Excessive diversification may lead to average returns and administrative hassle. Quality, diversification in style rather than numbers, and alignment with long-term goals rather than short-term trends or so-called yesterday's stars are the interests of investors.
