The 7-Year Rule in Large Cap Funds: When Historical Loss Probability Reached Zero

By FundSageAI Research Team•29 October 2026
Institutional Whitepaper
Key Empirical Takeaways
  • Rolling-window sample from daily Direct Growth NAV history; see the Methodology for the exact data span.
  • Zero cherry-picking: continuous rolling windows across complete market cycles.
  • Deterministic verification checks every cited statistic against the report's quant snapshot.

Large Cap Funds and Holding Periods: What the Loss Data Shows

How long has a lump-sum holding in a Large Cap fund needed to run before a negative return stopped appearing in the data? We looked at the daily rolling-return history of Direct Growth plans of currently active Large Cap schemes. The answer in this dataset is 7 years. The caveats matter as much as the headline.

Key Takeaways

  • Loss probability fell with each longer horizon. It was 16.44% at 1Y, 1.47% at 3Y, 0.16% at 5Y, and 0.0% at 7Y and 10Y.
  • 7Y is the zero-loss horizon in this data. None of the 54,106 daily rolling windows across 24 Direct Growth schemes ended negative.
  • The weakest 7Y outcome was still positive. It was +4.21% CAGR (Taurus Large Cap Fund, 23 Mar 2013 to 23 Mar 2020). The weakest 10Y outcome was +8.03% CAGR.
  • The limits are real. Only currently active schemes are included (survivorship bias), the data begins in 2013, and 7Y and 10Y windows rest on a limited set of start dates.

The Numbers at a Glance

Each row counts daily rolling windows, pooled across the stated number of Direct Growth schemes. Every figure is a lump-sum, point-to-point return.

What "Loss Probability" Means Here

Loss probability is the share of rolling windows that ended with a negative annualised return. A window starts on a given day and ends exactly 1, 3, 5, 7 or 10 years later. Windows start on every calendar day from 2013-01-01 up to each horizon's data end date. That is why shorter horizons have more windows.

The study uses Direct plans, Growth option, one series per scheme. Returns come from daily NAV history. The data is internally validated.

Shorter Holding Periods Showed Wider Outcomes

At 1Y, the middle half of outcomes ran from 2.9% to 24.88%, with a median of 11.49%. The worst 1Y window was -37.19% (HDFC Large Cap Fund, 23 Mar 2019 to 23 Mar 2020). The best was +98.07%.

By 7Y, the middle half ran from 12.22% to 14.84%, with a median of 13.56%. At 10Y, it ran from 12.82% to 15.13%, with a median of 13.98%. In the observed windows, the range of outcomes tightened as the holding period lengthened.

Where the 5Y Losses Came From

The 5Y loss probability of 0.16% is not spread evenly. Within the 5Y data, 2015 start dates show a loss probability of 1.55% of windows. Every other start year shows 0.0%. The worst 5Y window was -3.43% (Taurus Large Cap Fund, 23 Mar 2015 to 23 Mar 2020).

The 3Y figure follows a similar pattern. Only 2017 start dates show losses, at 16.61% of that year's windows. The 1Y picture is far more uneven. Start-year loss probability ranged from 0.0% for 2020 and 2023 starts to 45.18% for 2019 starts.

Beating Inflation in the Data

Using the 6.0% RBI CPI upper tolerance band as a threshold, the share of windows with annualised returns above it rose with the holding period.

Why the Caveats Matter

  1. Survivorship bias. The universe is currently active schemes only. Closed or merged schemes are excluded. A dataset that included them could look different.
  2. A short history. The data floor is 2013-01-01, when Direct plans launched. 7Y windows start between 2013-01-01 and 2019-10-01. 10Y windows start between 2013-01-01 and 2016-10-01. Neighbouring windows overlap heavily, so these results rest on a limited set of start dates.
  3. Category label. The label reflects today's SEBI classification, and earlier windows use today's membership. This study makes no claim about the category's history before 2017-10-06.
  4. Scope. Results are lump-sum only. They do not describe SIP investing, taxes, or other holding periods.
  5. Not a forecast. A 0.0% loss rate in the sample describes what happened in these windows. It does not show what future windows will do.

Frequently Asked Questions

What is the zero-loss horizon for Large Cap funds in this data?

It is 7 years. Across 54,106 daily rolling windows from 24 Direct Growth schemes, no 7Y window ended with a negative annualised return. The 10Y horizon also showed 0.0% loss across 28,952 windows from 22 schemes.

How often did Large Cap funds lose money over 1 year?

In 16.44% of 116,493 daily rolling windows across 33 Direct Growth schemes, the 1Y annualised return was negative. The weakest 1Y window was -37.19%.

Did any 5-year window lose money?

Yes. 5Y loss probability was 0.16% across 72,375 windows from 27 schemes. The worst 5Y outcome was -3.43%. The losses sat in 2015 start dates (1.55% of windows for that start year).

What was the weakest 7-year result?

The weakest 7Y outcome was +4.21% CAGR, from Taurus Large Cap Fund between 23 Mar 2013 and 23 Mar 2020. The median 7Y outcome was 13.56%.

Does 0.0% historical loss mean a 7-year loss cannot happen?

No. The data covers a limited history starting in 2013 and includes only currently active schemes. Historical distributions do not predict future returns.

Do these figures apply to SIP investing?

No. Every statistic is a lump-sum, point-to-point return. SIP cash flows are not modelled.

Which plans and schemes are in the study?

The study uses Direct plans, Growth option, one series per scheme, for currently active Large Cap schemes. Closed or merged schemes are excluded, which creates survivorship bias.
