As an equity index, its performance is directly influenced by overall market movements, economic conditions and changes in corporate earnings.

Small cap companies may experience sharper price fluctuations compared to large cap stocks, especially during uncertain market phases.
Liquidity Risk
Although constituents are selected using liquidity criteria, trading volumes in small cap stocks may still be lower than in larger companies during stressed conditions.

Reconstitution Impact
Periodic semi-annual reviews may lead to changes in constituents, which can alter sector weights and stock representation over time.

How does Bajaj Finserv Small Cap Fund use the BSE 250 SmallCap TRI?
The BSE 250 SmallCap TRI serves as the benchmark for Bajaj Finserv Small Cap Fund and acts as a comparative yardstick for evaluating how the portfolio performs over time. Because the TRI version factors in reinvested dividends along with price changes, it reflects total return performance of the broader small cap segment.
That said, the fund is not structured to mirror the benchmark. It follows an active investment strategy and builds its portfolio through independent stock selection within the small cap universe, which can lead to differences in holdings, sector exposure and weight distribution when compared with the index.
In essence, while the benchmark provides a reference for performance measurement, the portfolio construction is guided by the scheme’s investment objective and research-led framework. For detailed scheme information, click here.
