The Real Cost of Diversification: What Volatility and Drawdown Data Actually Show
A recent Cafemutual study of AMFI's June 2026 data found something interesting. Retail investors in India hold over 91% of their mutual fund money in equity. Only 2.75% is in debt. HNIs look very different - they hold 69% in equity, and spread the rest across debt, hybrid funds and ETFs.
The easy answer to this gap is: "HNIs are missing out on returns. Equity gives the best long-term returns. Why hold anything else?"
That answer is not wrong. But it is not complete. It looks only at returns and stops there. This piece is about two numbers that answer leaves out - volatility and drawdown. These two numbers show a cost that a simple return figure never shows.
The setup
Why we used a 6-year window. Most people invest with a clear time period in mind. For salaried people saving for a house, a child's education, or retirement, 5 to 7 years is a common time frame. We used two 6 -year blocks (2014–2019 and 2020–2025) because this matches how real investors actually experience the market - as one or two multi-year stretches, not as one long 12-year average.
Why we picked these two funds. We compared:
ICICI Prudential Multicap Fund – Direct Growth - 100% equity, spread across large, mid and small cap stocks
ICICI Prudential Balanced Advantage Fund - Direct Growth - a fund that actively manages a mix of equity and debt
We picked a balanced advantage fund because of how it usually behaves, not just its name. Across many market cycles, these funds usually keep 25 - 35% in debt on average. The equity part moves up and down based on market prices, but the debt part gives it stability. If we take 30% as the average debt level, a 50:50 split between our multicap fund and this balanced advantage fund gives roughly 15% debt exposure in the total portfolio. This is real diversification - without needing a separate debt fund.
Three strategies compared, in each period:
100% Multicap
100% Balanced Advantage
50:50 blend of both, rebalanced back to equal weight every year
All numbers use actual daily NAV data from AMFI records - not estimates.
Block 1 : January 2014 - December 2019
| Strategy | 1,00,000 became | CAGR | Max Drawdown | Volatility (annualized) | Sortino Ratio |
|---|---|---|---|---|---|
| 100% Multicap | 2,44,400 | 16.06% | -17.3% | 13.1% | 1.10 |
| 100% Balanced Advantage | 2,13,200 | 13.45% | -10.7% | — | — |
| 50:50 Blend (rebalanced annually) | 2,27,500 | 14.68% | -14.3% | 10.1% | 1.22 |
Equity wins on CAGR here - no doubt. But look at the other three columns. Equity's drawdown of -17.3% (from August 2015 to February 2016) was 3 percentage points worse than the blend's -14.3%. Its volatility, at 13.1%, was 30% higher than the blend's 10.1%. And on Sortino ratio - a measure of return per unit of downside risk - the blend actually did better: 1.22 vs 1.10.
Block 2 : January 2020 - December 2025
| Strategy | 1,00,000 became | CAGR | Max Drawdown | Volatility (annualized) | Sortino Ratio |
|---|---|---|---|---|---|
| 100% Multicap | 2,82,900 | 18.92% | -38.9% | 17.0% | 1.01 |
| 100% Balanced Advantage | 2,11,200 | 13.27% | -27.0% | — | — |
| 50:50 Blend (rebalanced annually) | 2,40,800 | 15.77% | -33.0% | 13.2% | 0.97 |
Equity leads again on CAGR. But the drawdown gap is the real story here. Equity fell 38.9% from peak to bottom during the COVID crash (January - March 2020). The blend fell only 33.0%. That is almost 6 percentage points of loss avoided. Volatility followed the same pattern - 17.0% for equity against 13.2% for the blend.
Here, the Sortino ratio slightly favours pure equity (1.01 vs 0.97). This is a good reminder that risk -adjusted numbers don't always favour diversification. The fast, sharp recovery after COVID helped pure equity's risk-adjusted score in this specific period.
The full 12-year picture: January 2014 – December 2025
| Strategy | 1,00,000 became | CAGR | Max Drawdown | Volatility (annualized) | Sortino Ratio |
|---|---|---|---|---|---|
| 100% Multicap | 6,93,300 | 17.51% | -38.9% | 15.2% | 1.04 |
| 100% Balanced Advantage | 4,50,800 | 13.37% | -27.0% | 8.8% | 1.12 |
| 50:50 Blend (rebalanced annually) | 5,47,800 | 15.23% | -33.0% | 11.7% | 1.06 |
Over the full 12 years, this same pattern gets even clearer. Equity's final value is much higher - almost 1.5 lakh more than the blend, on a starting amount of 1 lakh. But this extra return came with 30% more volatility and a maximum fall that was almost 6 percentage points worse than the blend's.
Answering the obvious question
If you've read this far, you're probably thinking: "Fine, but equity still made more money in every single row of every table. Why would I give that up?"
Here is the answer, using the two numbers most people skip past:
A -38.9% fall needs a 64% rise just to break even. A -33.0% fall needs only 49%. This gap works against you exactly when you can least handle it - during a market fall, when confidence (and often income) is already under pressure. The investor holding 100% equity in March 2020 needed the market to recover significantly more to get back to where they started compared to an investor holding a portfolio with a blend.
Volatility is not just a number - it affects your decisions. A portfolio with 15.2% volatility moves up and down more sharply, and more often, than one with 11.7%. Each of these swings is a moment where an investor has to decide: hold, sell, or panic. More swings mean more decisions. More decisions mean more chances to make the wrong one at the worst time.
The CAGR table assumes an investor who never panics. It is only a backtest. It does not show what a -39% fall actually feels like to someone watching their retirement savings, or their child's education fund, fall in real time. The difference between "what the math says you should earn" and "what you actually keep" usually comes down to how you behave during a crash - not just the return of the fund itself.
The takeaway
Equity earns its place as the growth engine of a portfolio. The numbers here prove that clearly, in both cycles and across the full 12 years. But looking only at returns means looking at only half the picture. Volatility and drawdown are the other half. These two numbers decide whether an investor actually stays invested long enough to earn the return that the CAGR table promises.
In this study, a 50:50 blend gave up about 2.3 percentage points of CAGR over 12 years. In return, it cut annualized volatility by roughly a quarter, and made the worst crash almost 6 percentage points smaller. Whether this trade is worth it is not really a math question. It depends on how you are likely to behave the next time markets fall 30% or more in a few weeks.
A few honest points to note
This is based on two funds over two time periods. It is not a universal rule for all equity vs. all hybrid funds, in every market condition, forever.
Past performance of these specific funds does not guarantee how they, or similar funds, will perform in future.
The 30% average debt figure used to estimate "effective debt exposure" is a general pattern seen in the balanced advantage category. It is not fixed - actual allocation changes based on market conditions.
A 50:50 split is just one option among many. The right mix for you depends on your goals, your time horizon, and how much risk you can take - which is the whole idea behind goal-based investing.
