Understanding Diversification and Investing in Uncorrelated Assets

Investing is a game of endurance. If you cannot stay in the game, you cannot win it. Diversification is what keeps you in the game. It is often described as the only free lunch, but many investors turn that free lunch into a buffet and end up with indigestion. The goal is not to own everything, or “diworsify,” as coined by Peter Lynch referring to reckless or inefficient diversification of a portfolio, which adds excessive, unnecessary investments that increase complexity and risk while reducing overall returns.

A simple way to think about diversification is correlation. If two assets move together, you have not diversified; you have doubled down. If they move differently, one can cushion the other when the world changes. Importantly, correlation is not a constant. It shifts during stress. So, the right question is not what was uncorrelated last year, but what tends to behave differently when equities are under pressure.

Using the same period as the accompanying portfolio NAV series (2010 to 2026), we look at annual returns across three building blocks: Equity, gold and bonds. Equity and gold show a negative correlation of -0.23. Bonds, however, show a very high positive correlation with equities (0.99), which means they did not behave like a classic shock absorber in this sample. The lesson is straightforward: Diversification has to be measured, not assumed.

There is also a subtle difference between uncorrelated and negatively correlated. Uncorrelated assets reduce noise; negatively correlated assets can act like a form of insurance. In this dataset, gold is the closest thing to that insurance against equity swings. Bonds, despite their reputation as a stabiliser, did not provide much diversification when equities moved. That is a useful reminder that the same asset can play a different role in a different macro regime.

Diversification shows up not just in correlations, but in drawdowns. Compare two wealth paths built from the NAV series: 100 percent equity, and a 60/20/20 mix of equity, gold and bonds. From January 1, 2010, to January 20, 2026, the diversified mix delivered a CAGR of 10.91 per cent vs 10.24 per cent for equity, with lower volatility (9.76 per cent vs 16.29 per cent) and a smaller maximum drawdown (-22.59 per cent vs -38.44 per cent). In practice, the smoother journey is often the edge, because it reduces the odds of a forced exit during bad markets.

How does an investor apply this without turning the portfolio into a museum?

First, diversify by risk factors, not by the number of holdings. Owning 10 banks is not diversification if a credit cycle turns. Diversification is exposure to different cash-flow drivers: Growth, inflation, interest rates and liquidity. Equities are primarily a growth asset. Bonds are largely an interest-rate and liquidity asset. Gold is an inflation and confidence asset. Cash is an optionality asset.

Second, keep the core simple and robust. For most investors, the real job is to build a sensible core allocation that matches time horizon, then rebalance. Rebalancing is the discipline that forces you to sell a bit of what has run up and buy a bit of what has lagged, without needing to predict the future. It also quietly harvests volatility.

Third, accept that some diversification will look wrong at any point in time. In strong equity markets, gold and bonds can feel like dead weight. In stressed markets, they feel like the best decision you ever made. The purpose of uncorrelated assets is not to outperform equities every year; it is to reduce the risk of a forced sale, and to provide dry powder when prices are attractive.

Fourth, avoid diworsification. Adding assets you do not understand, or adding themes that are really just the same equity risk in a different wrapper, does not help. A good test is to ask: What scenario makes this asset useful? If you cannot answer that clearly, you probably do not need it.

Finally, match diversification to your real-world liabilities. If your expenses are in rupees, domestic fixed income is relevant. If your goals include large near-term cash needs, liquidity matters more than cleverness. Your portfolio should reflect your life, not your neighbour’s.

Diversification is humble investing. It admits we do not know the future. It replaces the hope of being perfectly right with the confidence of being roughly right and staying solvent. In markets, survival is not a soft skill. It is the skill that makes compounding possible.
