The case for multi-asset investing is becoming increasingly relevant for mutual fund investors as the industry sees sustained interest in strategies that combine equity, debt and gold rather than relying on a single asset class.
A September 2026 study by WhiteOak Capital, Chemistry of Investing – A Study of Multi Asset Allocation Concept, demonstrates that adding equity to a debt portfolio does not necessarily mean proportionately higher volatility. In fact, the study shows that a carefully constructed mix can improve returns while keeping volatility relatively contained.
The analysis uses daily 1-year rolling returns between September 2001 and August 2026, with the CRISIL 10 Year Gilt Index representing debt and BSE Sensex TRI representing equity. A 100% debt portfolio generated an average annual return of 6.76% with 6.37% volatility. Adding 10% equity actually reduced volatility to 5.76%, while increasing the average return to 7.95%.
The more interesting combination in the study is a portfolio with 75% debt and 25% equity. It generated an average annual return of 9.74%, with volatility of 7.09%, which is only modestly higher than the 100% debt portfolio but with a substantially higher return.
Gold changes the equation
The study then adds gold as a third asset class. A portfolio comprising 55% debt, 25% equity and 20% gold generated an average annual return of 11.59% with volatility of 6.81% over the same period.
That is particularly notable because the portfolio delivered almost the same volatility as the 100% debt portfolio, while generating nearly 3 percentage points more average return.
The underlying argument is diversification through correlation. WhiteOak’s analysis shows Indian equity and gold had a correlation of -0.43, while Indian equity and debt had a correlation of -0.06 over January 2010 to August 2026. US equity had a correlation of 0.37 with Indian equity but was negatively correlated with debt at -0.14.
This diversification argument also has a practical dimension. In the study’s sample portfolio, comprising 25% domestic equity, 45% debt, 25% gold and 5% US equity, annual rebalancing produced a return of 13.02% in FY11 and helped moderate the impact of years when individual asset classes performed poorly.
Flows suggest investors are already warming up to the idea
The argument comes at a time when multi-asset allocation funds have been attracting meaningful investor money.
According to the multi-asset flow data recently released by AMFI, these funds received inflows of Rs. 3,671 crore in August, Rs. 4,811 crore in June 2026 and Rs. 3,753 crore in July. Despite the decline, August flows remained substantial and came against total hybrid fund inflows of Rs. 10,045 crore.
The trend has also been visible over a longer period. In December 2025, multi-asset allocation funds attracted Rs. 7,426 crore, accounting for nearly 70% of the Rs. 10,756 crore that flowed into hybrid funds that month.
Cafemutual Take
For the mutual fund industry, this provides an important backdrop. Multi-asset funds offer a product structure where the diversification decision is embedded within the scheme rather than requiring investors to separately allocate across equity, debt and gold and periodically rebalance the portfolio.
The WhiteOak study itself highlights this point: economic cycles and markets keep changing, making it difficult to consistently identify the best-performing asset class. A mix of asset classes with different correlations can potentially help investors pursue risk-adjusted returns over the long term.
Note: WhiteOak’s calculations are illustrative and do not represent the performance of any particular scheme. The study itself cautions that past performance may not be sustained.
