Harish Krishnan, CIO at Aditya Birla Sun Life AMC, has cautioned investors about buying low-quality small-cap stocks. Despite record inflows of Rs 7,973 crore into the segment in August 2026, he highlights that many companies are trading at high valuations that may not be supported by their actual business performance.
Harish Krishnan, Chief Investment Officer (Equity) at Aditya Birla Sun Life Mutual Fund, has issued a note of caution regarding the small-cap stock segment. While the sector recently saw massive interest from domestic investors, with inflows hitting a record Rs 7,973 crore in August 2026, the fund manager suggests that investors should be careful about which companies they are buying.
The core of the concern lies in valuations. Small-cap stocks are currently trading at a significant premium, estimated at nearly 49% above their long-term average prices. When prices rise this quickly across the entire sector, it becomes harder for investors to find companies that are truly worth the high price they are paying. Krishnan emphasizes that simply looking for growth is not enough in this market environment.
He defines "quality-deficient" businesses as those that lack a clear business advantage, struggle to manage their cash flow, or fail to maintain financial discipline. In the current market, strong domestic money flowing into mutual funds has acted as a cushion, helping to stabilize prices even when foreign investors sell. However, this same high volume of buying can sometimes push up the prices of even weak companies that do not have the fundamental strength to survive tough business cycles.
For investors, this means the strategy of buying small-cap stocks blindly because of recent momentum may carry risks. Krishnan advises focusing on companies that demonstrate three specific traits. First, they should show consistent earnings visibility, meaning the company can accurately predict its future profits. Second, they need a healthy balance sheet, which refers to manageable debt levels and efficient use of money. Third, they should have a clear competitive advantage that allows them to maintain profit margins even when the economy slows down.
The warning serves as a reminder that not all small-cap companies are the same. While some firms have improved their operations post-pandemic by reducing interest costs and increasing efficiency, others are merely riding the wave of sector-wide hype. As valuation gaps between good and average companies widen, the ability to select the right business becomes more important than just following the broader trend.
Investors looking at the small-cap space may want to pay close attention to management quality and the company’s history of generating cash. Relying on past performance alone can be misleading, as market conditions change. The next important step for investors is to review whether their current holdings have the financial strength to handle potential market volatility, especially as global factors like interest rate changes continue to influence sentiment.
