Rolling Returns
Tech Mahindra Ltd.
Every 15-year stretch TECHM has been through — 61 of them, each starting a month after the last. The median returned 16.7% a year, the worst 9.1%, the best 25.6%. 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 11.2% a year. The worst lost 77.7% a year and the best made 311.6%.
Worst start: December 2007 — -77.7% a year for the 1 years that followed.
Best start: November 2008 — 311.6% a year.
Against the Nifty 500: TECHM came out ahead in 54.1% of the 229 windows both series cover.
Across 205 separate 3-year holding periods, the median returned 15.8% a year. The worst lost 24.2% a year and the best made 68.8%.

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, TECHM finished ahead of the Nifty 500 in 95.1% of the 61 periods both series cover.
1-year windows
Ahead in 54.1% of 229 periods.
3-year windows
Ahead in 59.5% of 205 periods.
5-year windows
Ahead in 72.9% of 181 periods.
7-year windows
Ahead in 92.4% of 157 periods.
10-year windows
Ahead in 82.6% of 121 periods.
15-year windows
Ahead in 95.1% 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 TECHM'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, Tech Mahindra Ltd. has been through 61 separate 15 years holding periods — one starting every month. The median returned 16.7% a year, the worst 9.1% and the best 25.6%. 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 1.2% 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 Tech Mahindra Ltd. has been listed.
-18.8% a year, for the five years beginning December 2006. For contrast the best 5 years returned 50.3% a year, starting November 2008, and the median across all 181 periods was 18.5%. 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 -77.7% to 311.6% a year — a spread of 389.3%. 15 years outcomes ranged from 9.1% to 25.6%, a spread of 16.5%. 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 95.1% 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 Tech Mahindra 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 Tech Mahindra 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.
