Building an investment portfolio is not only about choosing between equity, debt and gold. The proportion allocated to each asset can also change the returns and volatility an investor experiences over time.
FundsIndia Research compared several combinations of equity, debt and gold using rolling returns from January 2000 to July 2026. The analysis looked at portfolios ranging from equity-heavy allocations to portfolios with a larger share of debt and gold.
The findings show that there was no single allocation that delivered the highest return across every period. However, the 70% equity, 15% debt and 15% gold combination stood out for its balance of returns and consistency over seven-year periods.
Which equity, debt and gold combination delivered the best returns?
FundsIndia compared six combinations across seven-year rolling periods. These included three equity-debt portfolios and three portfolios that added gold to the mix.

| 30% equity, 70% debt | 10.7% | 8% | 16% | 49% |
| 70% equity, 15% debt, 15% gold | 15.0% | 7% | 28% | 92% |
| 50% equity, 25% debt, 25% gold | 14.2% | 7% | 24% | 81% |
| 30% equity, 35% debt, 35% gold | 13.2% | 6% | 20% | 72% |

The 70:15:15 portfolio recorded the highest average return among the six asset-allocation combinations at 15%. It also delivered annualised returns above 10% in 92% of seven-year rolling periods.
The 70% equity and 30% debt portfolio, by comparison, averaged 13.8% and crossed 10% in 87% of seven-year periods. The more conservative 30% equity, 70% debt portfolio averaged 10.7% and crossed 10% in only 49% of periods.
Adding more gold did not necessarily improve the outcome. The 50:25:25 portfolio averaged 14.2%, while the 30:35:35 combination averaged 13.2%. This suggests that the allocation to gold and debt matters as much as simply having multiple asset classes in a portfolio.
Did adding debt and gold reduce portfolio risk?
The seven-year rolling data shows that the portfolios with debt and gold had lower maximum drawdowns than pure equity.
The 70:15:15 portfolio had a maximum drawdown of 40%, the same as the 70% equity and 30% debt portfolio. The 50:25:25 portfolio had a maximum drawdown of 27%, while the 30:35:35 portfolio had a maximum drawdown of 17%. Nifty 50 TRI, meanwhile, recorded a maximum drawdown of 59% over the period studied.

Maximum drawdown |
| 70% equity, 30% debt | 13.8% | -40% |
| 50% equity, 50% debt | 12.5% | -27% |
| 30% equity, 70% debt | 10.7% | -14% |
| 70% equity, 15% debt, 15% gold | 15.0% | -40% |
| 50% equity, 25% debt, 25% gold | 14.2% | -27% |
| 30% equity, 35% debt, 35% gold | 13.2% | -17% |
| Nifty 50 TRI | 15.0% | -59% |

The comparison becomes more interesting when looking at the minimum seven-year return. Nifty 50 TRI’s minimum rolling return was 5%, compared with 7% for the 70:15:15 portfolio. The 50:25:25 and 30:35:35 portfolios also had minimum returns of 7% and 6%, respectively.
Does the 70:15:15 allocation work over five years too?
The pattern is not limited to seven-year periods. Over five-year rolling periods, the 70:15:15 portfolio delivered an average annualised return of 15.6%, compared with 14.4% for 70:30 equity-debt and 16% for Nifty 50 TRI.
More importantly, the 70:15:15 portfolio delivered more than 10% annualised returns in 85% of five-year rolling periods. The corresponding figure was 79% for the 70:30 equity-debt portfolio and 77% for Nifty 50 TRI.
This does not establish that 70:15:15 is the universally “best” portfolio. The outcome depends on the investor’s time horizon, risk tolerance and financial goals. What the historical analysis does show is that a portfolio combining equity with moderate allocations to debt and gold produced a strong combination of average returns and consistency across the periods studied.
FundsIndia’s analysis assumes the portfolio is rebalanced annually whenever an asset allocation deviates by more than 5% from the target allocation. The returns are therefore based on maintaining the stated allocation rather than simply buying the assets once and leaving them untouched.
The broader takeaway from the 25-year data is that asset allocation can materially change an investor’s experience even when the equity component remains the main driver of returns. The right mix is therefore not simply about maximising returns, but about balancing return potential with the size of losses an investor may have to withstand.
