Rolling Returns
Tata Chemicals Ltd.
Every 15-year stretch TATACHEM has been through — 61 of them, each starting a month after the last. The median returned 21.4% a year, the worst 14.4%, the best 27.7%. 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 229 separate 1-year holding periods, the median returned 13.4% a year. The worst lost 59.3% a year and the best made 248.5%.
Worst start: February 2008 — -59.3% a year for the 1 years that followed.
Best start: March 2020 — 248.5% a year.

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 15-year windows, TATACHEM finished ahead of the Nifty 500 in 100.0% of the 61 periods both series cover.
1-year windows
Ahead in 59.0% of 229 periods.
3-year windows
Ahead in 71.2% of 205 periods.
5-year windows
Ahead in 91.7% of 181 periods.
7-year windows
Ahead in 100.0% of 157 periods.
10-year windows
Ahead in 100.0% of 121 periods.
15-year windows
Ahead in 100.0% of 61 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 TATACHEM'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 15 years, Tata Chemicals Ltd. has been through 61 separate 15 years holding periods — one starting every month. The median returned 21.4% a year, the worst 14.4% and the best 27.7%. 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 121 10 years periods the record covers. The weakest of them still compounded at 11.2% a year. That is a statement about the past, not a guarantee about any future 10 years, and it is measured only over the years Tata Chemicals Ltd. has been listed.
-3.6% a year, for the five years beginning March 2021. For contrast the best 5 years returned 46.6% a year, starting February 2016, and the median across all 181 periods was 20.4%. 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 -59.3% to 248.5% a year — a spread of 307.8%. 15 years outcomes ranged from 14.4% to 27.7%, a spread of 13.3%. 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 61 15 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 Tata Chemicals 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 Tata Chemicals 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.
