MF Tracker: Bank of India Small Cap Fund Tops Equity Funds With 25.21% Returns in 7 Years. Can the Run Continue?
Bank of India Small Cap Fund has delivered an impressive 25.21% annualised return over seven years, emerging as the best-performing equity mutual fund in ETMutualFunds' analysis excluding sectoral and thematic funds. However, high small-cap valuations, rising investor inflows and the inherently volatile nature of the segment raise questions about whether the fund can sustain its exceptional performance.

Bank of India Small Cap Fund Delivers 25.21% CAGR in Seven Years
Bank of India Small Cap Fund has emerged as the top-performing equity mutual fund over a seven-year period, according to an ETMutualFunds analysis based on daily rolling returns.
The fund delivered an annualised return, or CAGR, of approximately 25.21% over seven years, the highest among 163 equity mutual funds considered in the analysis, excluding sectoral and thematic schemes.
Such a return is significant because small-cap funds invest predominantly in smaller companies, where the potential for growth can be high but price volatility can also be substantial.
How Has the Fund Performed?
Bank of India Small Cap Fund has built a strong long-term performance record since its launch in December 2018. The scheme is designed to generate long-term capital appreciation by investing predominantly in small-cap companies.
According to the fund house, its benchmark is the NIFTY Smallcap 250 Total Return Index, and the scheme carries a "very high" risk classification because of its equity and small-cap exposure.
Recent performance data also shows that the fund has remained competitive over shorter periods. However, investors should not assume that its recent or seven-year performance will automatically be repeated in the future.
What Has Driven the Strong Performance?
One important factor behind the fund's performance is its ability to participate in the growth of smaller companies.
Small-cap stocks can generate substantial returns when earnings, business prospects and investor sentiment improve. At the same time, smaller funds may have greater flexibility to invest in companies that could be difficult for very large schemes to enter or exit without affecting market prices.
A recent analysis by Financial Express noted that Bank of India Small Cap Fund's relatively small asset base can provide an advantage in the small-cap segment, while also pointing out that the fund's volatility has been relatively high.
Can 25.21% Returns Continue?
This is the biggest question for investors.
A seven-year CAGR of 25.21% is an exceptional historical performance, but it should not be treated as an expected future return. Mutual fund returns fluctuate according to market valuations, earnings growth, interest rates, liquidity and investor sentiment.
Small-cap stocks are particularly sensitive to changes in market sentiment. If valuations become stretched or economic growth slows, these stocks can experience sharper corrections than larger companies.
Therefore, investors should avoid choosing the fund solely because it currently ranks first on a seven-year return chart.
Small-Cap Valuations Remain an Important Risk
Valuation is one of the biggest concerns surrounding the small-cap segment.
When investors become highly optimistic about smaller companies, stock prices can rise faster than underlying earnings. This can make future returns more difficult to generate.
ETMutualFunds has also highlighted concerns about high small-cap valuations and increasing investor inflows into the category. Growing inflows can create the risk of overcrowding, particularly when investors chase past performance.
For investors, the key question is therefore not simply whether a fund has delivered high returns in the past, but whether its portfolio companies can continue to justify their valuations through earnings and business growth.
What About the Fund's Risk?
The fund's strong returns have come with meaningful volatility.
Financial Express reported that Bank of India Small Cap Fund's five-year annualised return was around 20.76%, compared with approximately 16.13% for the Nifty Smallcap 250 TRI. However, its volatility was also higher than the index in the period examined.
This highlights an important point: higher returns in small-cap funds can come with higher fluctuations.
Investors should therefore look at risk-adjusted performance, drawdowns and volatility rather than focusing only on CAGR.
Fund Size and Portfolio Flexibility
The fund's relatively modest asset size can potentially provide greater flexibility in the small-cap universe.
Large funds may find it difficult to build meaningful positions in very small companies without influencing their market prices. A smaller fund can potentially take positions in such companies more easily.
However, smaller size does not automatically mean better returns. Stock selection, portfolio construction, risk management and valuation discipline remain crucial.
Should Investors Chase the Fund After Its Strong Performance?
Past performance should be used as one input in the investment decision rather than the sole reason for investing.
An investor considering Bank of India Small Cap Fund should evaluate factors such as:
Investment objective and portfolio strategy
Long-term performance across different market cycles
Performance against its benchmark
Portfolio concentration
Volatility and maximum drawdown
Expense ratio
Fund manager and investment-process continuity
Current valuations of the underlying holdings
Personal investment horizon and risk tolerance
The fund house itself classifies the scheme as suitable for investors seeking long-term capital appreciation through predominantly small-cap equity exposure and marks the principal risk as very high.
What Allocation Should Investors Have in Small Caps?
Small-cap funds generally make more sense as part of the equity allocation for investors who can tolerate substantial short-term fluctuations and have a long investment horizon.
There is no universally suitable percentage for every investor. The appropriate allocation depends on age, financial goals, existing equity exposure, income stability, emergency savings and risk tolerance.
Investors who already have significant exposure to mid-cap and small-cap stocks should also consider whether adding another small-cap fund would unnecessarily increase portfolio concentration.
SIP May Be More Suitable Than Chasing a Lump-Sum Entry
Investors who want exposure to small-cap funds but are uncomfortable with market timing may consider systematic investing.
A SIP spreads purchases over time and can reduce the risk of investing a large amount immediately before a market correction. However, SIPs do not eliminate market risk and cannot guarantee positive returns.
The objective should be to maintain an appropriate long-term asset allocation rather than attempting to identify the next best-performing fund every year.
The Bottom Line
Bank of India Small Cap Fund's 25.21% seven-year CAGR is an impressive achievement and places it at the top of ETMutualFunds' analysis of equity funds excluding sectoral and thematic schemes.
However, the performance should be viewed in the context of the risks involved. Small-cap valuations are elevated, investor participation has increased and the segment can experience sharp corrections.
The fund may continue to perform well if its portfolio companies deliver strong earnings growth and the investment strategy remains effective. But expecting another 25% CAGR simply because the fund delivered it in the past would be risky.
For investors, the better approach is to assess the fund's current portfolio, valuation, risk-adjusted returns and suitability within the overall portfolio rather than chasing the historical winner.
