When comparing AMCs, the question is not which fund had the best 1-year return - that is random. The question is which AMC has delivered consistent alpha above its benchmark across multiple funds and multiple time periods. The answer is not straightforward, and the last three years have been humbling for several AMCs that had strong prior track records.

Defining Alpha Correctly

Alpha is excess return above the benchmark. A large cap fund is compared to Nifty 100 TRI. A mid cap fund to Nifty Midcap 150 TRI. A flexi cap fund typically to Nifty 500 TRI.

Using the wrong benchmark inflates perceived alpha. Some AMCs compare large cap funds to Nifty 50 instead of Nifty 100 - Nifty 100 includes more stocks and typically has a lower return in bull markets, making alpha look smaller. Always check which benchmark the fund uses and whether it is appropriate.

HDFC AMC: The Established Player

HDFC AMC manages India’s largest equity AUM. Their flagship funds have long track records.

Fund Category 5-Year Alpha vs Benchmark (approx) Fund Manager
HDFC Flexi Cap Flexi Cap +2 to +4% p.a. Roshi Jain / Gopal Agrawal
HDFC Mid-Cap Opportunities Mid Cap +2 to +5% p.a. Chirag Setalvad
HDFC Top 100 Large Cap Flat to +1% p.a. Rahul Baijal
HDFC Small Cap Small Cap +3 to +5% p.a. Chirag Setalvad

HDFC’s mid and small cap funds have been more consistent alpha generators than their large cap offering. The large cap category is crowded and genuinely difficult to outperform given that active funds here face the highest scrutiny from institutional money. HDFC’s alpha in large cap has been thin, justifying index fund substitution in that category.

Axis AMC: The Rise and Fall

Axis mutual fund was the darling of the retail investor community between 2018-2021. Their large cap and flexi cap funds were consistently top quartile. Then 2022 arrived.

Several Axis AMC funds underperformed significantly in 2022-2023, coinciding with a change in fund management style and a broader quality-growth rotation hitting headwinds. The Axis Bluechip Fund, which was the poster child of the quality-at-any-price investing style, delivered negative alpha versus its benchmark for multiple consecutive years.

Fund 2019-2021 Alpha (approx) 2022-2024 Alpha (approx)
Axis Bluechip +4 to +6% -3 to -5%
Axis Midcap +5 to +8% -2 to +1%
Axis Flexi Cap +4 to +7% -2 to -4%

This reversal is one of the most cited examples in Indian investing of why trailing 3-year returns are not a reliable predictor of future performance. Investors who switched into Axis funds in 2021 based on the strong recent record were holding the worst-performing AMC’s funds in 2022-2023.

Mirae Asset: The International Entrant

Mirae Asset is a Korean AMC that entered India in 2008 and has built a strong track record across their equity lineup.

Fund Category 5-Year Alpha vs Benchmark (approx)
Mirae Asset Large Cap Fund Large Cap +1 to +3% p.a.
Mirae Asset Emerging Bluechip Large & Midcap +3 to +6% p.a.
Mirae Asset ELSS Tax Saver ELSS +2 to +4% p.a.
Mirae Asset Midcap Mid Cap +2 to +4% p.a.

Mirae’s consistent strength has been across both large cap and large-and-mid cap categories. Their Emerging Bluechip Fund has been one of the better-documented large-and-mid cap funds with consistent alpha. However, the fund was closed to lump sum investments for a period due to AUM concerns about maintaining performance at scale.

The Scale Problem

All three AMCs face the same structural problem as their AUM grows: it becomes harder to generate alpha. A fund managing Rs 20,000 crore cannot take meaningful positions in small and mid cap stocks without moving the price. The alpha generation in mid and small cap mandates becomes constrained.

This is why the 5-year alpha for mid cap funds often looks better than large cap funds - not because the managers are better, but because the universe is more inefficient and easier to exploit with modest AUM.

Consistency Metrics: What to Actually Look at

Instead of comparing 5-year CAGRs, use rolling return analysis. Look at how often each fund beat its benchmark over rolling 3-year periods in the last 10 years.

AMC / Fund % of Rolling 3-Year Periods Beating Benchmark (10 years)
HDFC Mid-Cap Opportunities ~65-70%
Mirae Asset Emerging Bluechip ~70-75%
Axis Bluechip (post-2022 data) ~45-55%
Parag Parikh Flexi Cap ~75-80%

These are illustrative percentages. The point is that even the best active funds beat their benchmarks only 65-80% of rolling 3-year periods. In the remaining periods, an index fund would have been better.

The Practical Takeaway

No single AMC is consistently the best across all categories. HDFC is reliable in mid and small cap. Mirae has been strong in large-and-mid cap. Axis had a strong run that reversed. PPFAS has a differentiated portfolio with international exposure.

The decision framework should be:

  • Large cap: Index funds (TER advantage is hard to overcome)
  • Mid cap: Active funds still show measurable alpha; HDFC and Mirae have reasonable track records
  • Small cap: Active funds are more justifiable due to market inefficiency
  • Flexi cap: Either active (PPFAS) or index (Nifty 500); both defensible

Bottom Line

Mirae Asset has had the most consistent alpha delivery across their major funds over the last 10 years. HDFC AMC’s mid and small cap funds have also been consistently solid. Axis’s strong 2018-2021 run reversed sharply in 2022-2023, illustrating why AMC selection based on recent performance is unreliable. No AMC bats above 75-80% on rolling 3-year alpha generation, which means even the best active funds underperform their benchmark roughly 25-35% of rolling periods. The appropriate response is to use index funds where evidence shows consistent active alpha is absent (large cap), and selectively use active funds in mid and small cap where the market is less efficient.
