Frequently asked questions
Which has a higher 3-year return, Motilal Oswal Nifty Midcap 150 Index Fund or Sundaram Nifty 100 Equal Weight Fund?
Motilal Oswal Nifty Midcap 150 Index Fund's 3-year rolling CAGR of 25.0% is higher than Sundaram Nifty 100 Equal Weight Fund's 17.1%. Motilal Oswal Nifty Midcap 150 Index Fund sits in the 98th percentile of its category on this metric, versus the 74th percentile for Sundaram Nifty 100 Equal Weight Fund - though note both funds may belong to different categories with different medians, so a raw CAGR comparison doesn't account for how each fund performed relative to its own peers. A higher historical return also doesn't necessarily mean lower risk; check the risk metrics below before concluding either fund is the "better" choice.
Which has a lower expense ratio, Motilal Oswal Nifty Midcap 150 Index Fund or Sundaram Nifty 100 Equal Weight Fund?
Motilal Oswal Nifty Midcap 150 Index Fund's direct-plan expense ratio is 0.37 percentage points lower than Sundaram Nifty 100 Equal Weight Fund's. Over long holding periods, a persistent expense-ratio gap compounds into a materially different final corpus even if the two funds' gross returns are similar - it's one of the few fund attributes you can compare with total certainty upfront, unlike future returns, since the fee is contractually fixed rather than a historical estimate.
Why don't Motilal Oswal Nifty Midcap 150 Index Fund and Sundaram Nifty 100 Equal Weight Fund show risk metrics like Sharpe ratio or alpha?
This fund tracks an index, so measuring alpha against that same index would only report its tracking error. This is a deliberate methodology choice, not missing data - risk metrics like alpha and Sharpe ratio are most meaningful for actively-managed funds where a manager makes decisions that can add or subtract value versus a benchmark. For a fund that mechanically tracks an index, the equivalent useful metric is tracking error (how closely it follows its index), not alpha.
Which has higher AUM, Motilal Oswal Nifty Midcap 150 Index Fund or Sundaram Nifty 100 Equal Weight Fund?
Motilal Oswal Nifty Midcap 150 Index Fund has ₹3,917 Cr in assets under management, versus ₹140 Cr for Sundaram Nifty 100 Equal Weight Fund. A larger AUM generally means deeper liquidity and lower per-unit fixed costs for the AMC to spread across investors, but an AUM that's very large relative to a fund's category and strategy (especially in small/mid cap categories, where the investable universe is smaller) can also make it harder for a manager to enter and exit positions without moving the price - bigger isn't automatically better, especially for less liquid categories.
Which fund has a longer track record, Motilal Oswal Nifty Midcap 150 Index Fund or Sundaram Nifty 100 Equal Weight Fund?
Sundaram Nifty 100 Equal Weight Fund launched on 1999-06-16, making it older than Motilal Oswal Nifty Midcap 150 Index Fund (launched 2019-08-19). A longer track record means more real market cycles (bull runs, corrections, rate cycles) the fund has actually navigated, which is useful context for judging consistency - but it isn't a guarantee of future performance, and a newer fund isn't automatically worse, especially if it's run by an experienced manager or team with a track record at a prior fund.
