Rolling Returns
IDBI Bank Ltd.
Every 15-year stretch IDBI has been through — 61 of them, each starting a month after the last. The median returned -1.5% a year, the worst -7.1%, the best 5.5%. 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 5.6% a year. The worst lost 63.3% a year and the best made 160.2%.
Worst start: November 2007 — -63.3% a year for the 1 years that followed.
Best start: March 2009 — 160.2% a year.
Against the Nifty 500: IDBI came out ahead in 41.9% of the 229 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 15-year windows, IDBI finished ahead of the Nifty 500 in 0.0% of the 61 periods both series cover.
1-year windows
Ahead in 41.9% of 229 periods.
3-year windows
Ahead in 31.2% of 205 periods.
5-year windows
Ahead in 18.2% of 181 periods.
7-year windows
Ahead in 2.5% of 157 periods.
10-year windows
Ahead in 0.0% of 121 periods.
15-year windows
Ahead in 0.0% 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 IDBI'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, IDBI Bank Ltd. has been through 61 separate 15 years holding periods — one starting every month. The median returned -1.5% a year, the worst -7.1% and the best 5.5%. 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.
Yes. 60.3% of the 121 10 years periods on record ended below where they started, and the worst of them lost 14.8% a year — the stretch beginning March 2010. The median period returned -2.1% a year.
-22.8% a year, for the five years beginning March 2015. For contrast the best 5 years returned 37.5% a year, starting May 2020, and the median across all 181 periods was -3.9%. 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 -63.3% to 160.2% a year — a spread of 223.5%. 15 years outcomes ranged from -7.1% to 5.5%, a spread of 12.7%. 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 0.0% 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 IDBI Bank 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 IDBI Bank 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.
