Rolling Returns
Bharat Dynamics Ltd.
Every 7-year stretch BDL has been through — 18 of them, each starting a month after the last. The median returned 38.9% a year, the worst 33.1%, the best 44.8%. A single headline CAGR hides all of that.
Every Holding Period
A rolling window is every possible start date, not one. A five-year window starting in January is a different investment from one starting in February, and over twenty years there are a couple of hundred of them. What follows is the full spread of what each holding period actually produced.
Across 90 separate 1-year holding periods, the median returned 30.7% a year. The worst lost 40.0% a year and the best made 186.8%.
Worst start: May 2025 — -40.0% a year for the 1 years that followed.
Best start: June 2023 — 186.8% a year.
Against the Nifty 50: BDL came out ahead in 68.9% of the 90 windows both series cover.
Across 66 separate 3-year holding periods, the median returned 49.6% a year. The worst lost 2.7% a year and the best made 109.8%.
Worst start: April 2018 — -2.7% a year for the 3 years that followed.
Best start: June 2021 — 109.8% a year.
Against the Nifty 50: BDL came out ahead in 86.4% of the 66 windows both series cover.
Across 42 separate 5-year holding periods, the median returned 50.5% a year. Not one of them ended in a loss — the weakest still compounded at 23.0% a year.
Worst start: March 2018 — 23.0% a year for the 5 years that followed.
Best start: May 2020 — 78.9% a year.
Against the Nifty 50: BDL came out ahead in 100.0% of the 42 windows both series cover.
Across 18 separate 7-year holding periods, the median returned 38.9% a year. Not one of them ended in a loss — the weakest still compounded at 33.1% a year.
Worst start: March 2018 — 33.1% a year for the 7 years that followed.
Best start: January 2019 — 44.8% a year.
Against the Nifty 50: BDL came out ahead in 100.0% of the 18 windows both series cover.
Windows step forward one month at a time and are measured on month-end adjusted closing prices, so dividends are treated as reinvested. Overlapping windows share months by construction — that is what makes the spread a description of this stock's history rather than a sample of independent trials.
Against The Index
Beating an index once is a result. Beating it across most of the periods an investor could have picked is a pattern. Over 7-year windows, BDL finished ahead of the Nifty 50 in 100.0% of the 18 periods both series cover.
1-year windows
Ahead in 68.9% of 90 periods.
3-year windows
Ahead in 86.4% of 66 periods.
5-year windows
Ahead in 100.0% of 42 periods.
7-year windows
Ahead in 100.0% of 18 periods.
Each window is compared against the index over the identical calendar months, on the same adjusted basis — not against an assumed rate of return.
How This Is Calculated
Windows step forward one month at a time, so they share most of their months with each other. That is what makes this a description of BDL's actual history rather than a set of independent trials — and why the spread should not be read as a probability.
Measured on month-end closing prices adjusted for dividends and splits, so dividends count as reinvested. A window that opened or closed mid-month would differ a little in either direction.

HELP CENTER
Everything you need to know about this page and the data presented.
Over 7 years, Bharat Dynamics Ltd. has been through 18 separate 7 years holding periods — one starting every month. The median returned 38.9% a year, the worst 33.1% and the best 44.8%. A rolling return measures every possible start date instead of one, which is why it answers a question a single headline CAGR cannot: how much the outcome depended on when you happened to buy.
No — not in any of the 18 7 years periods the record covers. The weakest of them still compounded at 33.1% a year. That is a statement about the past, not a guarantee about any future 7 years, and it is measured only over the years Bharat Dynamics Ltd. has been listed.
23.0% a year, for the five years beginning March 2018. For contrast the best 5 years returned 78.9% a year, starting May 2020, and the median across all 42 periods was 50.5%. The gap between those two numbers is the part of the outcome that came down to timing rather than to the company.
On this record, yes. 1 year outcomes ranged from -40.0% to 186.8% a year — a spread of 226.8%. 7 years outcomes ranged from 33.1% to 44.8%, a spread of 11.7%. Longer holding periods narrowed the range of results, which is the usual pattern and the reason this page publishes every window rather than one. Narrowing the range is not the same as removing the risk.
In 100.0% of the 18 7 years periods both series cover. Each window is compared against the index over the identical months, not against an assumed index return, so the comparison is a like-for-like record rather than a model.
Windows step forward one month at a time on month-end closing prices adjusted for dividends and stock splits, so dividends are treated as reinvested. A window length is only published once there are at least twelve complete windows behind it — fewer than that describes an anecdote, not a distribution. Overlapping windows share months by construction, which is what makes this a description of the actual history of Bharat Dynamics Ltd. rather than a sample of independent trials. Companies that delisted are not on this site at all, a survivorship bias worth holding in mind.
That is not a question this page answers, and we do not make recommendations. What it can show you is the full range of what every holding period in the listed history of Bharat Dynamics Ltd. actually produced — including the worst ones, which most performance figures leave out. Those are records of what happened, not forecasts. A stock that never had a losing decade may still have one, and holding a single company is a materially different risk from holding an index.
