Equity and debt funds: what each is for, and how they are taxed

Equity and debt funds are frequently compared on returns, which is the least useful basis for choosing between them. They do different jobs, and holding the wrong one for a given goal is a problem that only becomes visible at the worst moment.

What equity funds do

Equity funds invest in listed companies and are the principal way retail investors participate in corporate growth. Over long periods they have historically outpaced inflation more reliably than other liquid asset classes. Over short periods they do whatever they do, and a 30 per cent drawdown is a normal feature rather than an anomaly.

The categories differ meaningfully. Large-cap funds hold established companies and are the least volatile of the equity set. Mid and small-cap funds carry greater growth potential and considerably deeper drawdowns, and need longer horizons than most investors give them. Flexi-cap funds move across the spectrum at the manager's discretion. Sectoral and thematic funds concentrate risk deliberately and are not core holdings.

What debt funds do

Debt funds hold bonds and money market instruments. They provide relative stability and predictable behaviour, and they carry two risks that are often overlooked: interest rate risk, where prices fall as rates rise, and credit risk, where a borrower defaults.

Match the fund's duration to your horizon. Liquid and overnight funds suit money needed within months. Short-duration funds suit one to three years. Longer-duration funds are more sensitive to rate movements and are a view on rates as much as a parking place.

On credit risk, understand what the fund actually holds. A debt fund reaching for yield through lower-rated paper is taking equity-like risk while being described as conservative.

Equity funds are for growth you can wait for. Debt funds are for money you have already promised to something.

Taxation, which changes the comparison

Tax treatment differs by category and has been revised in recent years, including changes to how debt fund gains and holding periods are treated. Because the rules have moved more than once, the sensible approach is to confirm the current position for your specific fund category and holding period before transacting rather than relying on a figure remembered from a previous year.

What has remained true is that after-tax return is the only return that matters, and that a fund comparison conducted on pre-tax numbers can point in the wrong direction.

Hybrid funds

Hybrid categories hold both asset classes in defined proportions and rebalance automatically. Aggressive hybrids lean toward equity, conservative hybrids toward debt, and balanced advantage funds adjust the mix dynamically. For investors who want a single holding for a medium-horizon goal, these remove the need to rebalance manually.

Building the mix

Allocation should follow the goal's horizon and your capacity to tolerate a decline without selling - which is a practical question about your circumstances, not a personality test. An investor with an emergency fund and stable income can hold equity through a downturn. One without either will sell at the bottom regardless of intention.

Build the emergency fund first, in liquid instruments, before any long-horizon equity investing. It is what makes holding equity through a bad year possible at all.
