Summary: Everyone talks about HDFC, Kotak, Motilal Oswal or Nippon India when it comes to mid-cap mutual funds. But quietly, without grabbing headlines, one fund has outperformed them all in 10-year lump sum returns and shown remarkable consistency across time periods. Yet, it’s not even in the top 10 by asset size. So, why isn't everyone talking about it? Let’s find out which fund it is…
HDFC Midcap Opportunities, the giant in the room, manages over a staggering Rs 84,000 crore in net assets. Right behind it are Kotak Emerging Equity (topping Rs 57,000 crore), Nippon India Growth (more than Rs 39,000 crore) and Motilal Oswal Midcap (over Rs 33,000 crore).
And to be fair, these funds haven’t just attracted assets, they’ve delivered strong long-term returns. Let’s look at point-to-point 10-year returns, which tell you how much your money would have grown if you’d invested a lump sum 10 years ago (July 31, 2015):
- Kotak Emerging Equity: 19.05 per cent annualised return, the second best among all mid-cap funds in the last decade
- HDFC Midcap Opportunities: 18.48 per cent, the fourth best
- Motilal Oswal Midcap: 18.32 per cent, the fifth best
- Nippon India Growth: 17.81%, ranked sixth in the last 10 years
These numbers are certainly impressive. But wait—who’s No. 1?
That’s the surprise.
The top performer you’ve probably overlooked
Despite not being in the spotlight, Invesco India Midcap Fund has quietly outpaced all its peers with a 10-year annualised return of 19.31 per cent, making it the best-performing mid-cap fund in the last decade.
To put that return in perspective, if you had invested Rs 1 lakh in this fund 10 years ago, your investment would be worth around Rs 5.8 lakh today.
Yet, its asset size is just over Rs 7,000 crore, making them just the 16th largest mid-cap fund in the country.
And it’s not just lump-sum returns. Its SIP performance is equally stellar. Over the last 10 years, Invesco India Midcap has delivered 23.12 per cent annualised SIP returns, the second-best among all mid-cap funds—only Motilal Oswal Midcap edges ahead slightly. So, if you had started a Rs 10,000 monthly SIP in this fund 10 years back, you’d now be sitting on a cool Rs 40.8 lakh today.
But we don’t just look at point-to-point returns
While point-to-point returns are helpful, they depend heavily on the start and end date. Basically, this metric tells you how a fund did between two particular dates, but not how consistently it delivered returns along the way.
That’s why serious investors prefer rolling returns. They show how consistent a fund is over time.
What are rolling returns?
Instead of checking how the fund performed over one five-year period, we check it every single day. So, one day we check the return from Jan 1, 2018 to Jan 1, 2023. The next day, we check from Jan 2, 2018 to Jan 2, 2023. And so on.
Each of these is a new five-year window. This gives us a much clearer picture of how the fund performs across different time periods—not just one.
This tells you:
- How often the fund delivered strong returns
- How often it disappointed
This is a far better measure of consistency.
Therefore, we looked at daily 5-year rolling returns over the last five years and here’s how Invesco India Midcap Fund’s returns stack up across different ranges:
| 5-year rolling return band | Number of times (Days) |
|---|---|
| 5–10% | 64 |
| 10–15% | 340 |
| 15–20% | 409 |
| Above 20% | 421 |
| Total | 1234 |
- Only 64 out of 1,234 periods saw the fund return less than 10 per cent. That means over 94 per cent of the time, this fund delivered double-digit annualised returns over any five-year period between July 2020 and July 2025.
- Even more impressively, in nearly 7 out of 10 cases (67 per cent), the fund delivered more than 15 per cent annualised returns in the same period.
In short, the fund has been consistent, especially for a mid-cap fund, which typically sees sharp ups and downs.
Why have we focused on 10-year returns only?
Because mid-cap investing demands patience.
Mid-cap funds can go through long stretches of underperformance or even zero returns. But if you stay invested for 7 to 10 years, history suggests you’re likely to be handsomely rewarded.
The bottom line
Invesco India Mid Cap Fund is a classic case of a fund that lets its numbers do the talking. Strong SIP performance. Industry-best long-term returns. High consistency across rolling periods. And yet, relatively under-owned.
