Hercules Investments share price by year, month and day

Closes to 29 Oct 2026; the last month as traded on BSE

Hercules Investments' share price is on record from 17 Sep 2008, when it closed at ₹135.43, to 29 Oct 2026. Its highest close was ₹678.90 on 10 Oct 2024 and its lowest ₹36.80 on 12 Mar 2009, adjusted for 1 split or bonus issue. Some closes are BSE's, on days NSE has none. Its trading goes back to 2 Jan 2007, but prices before 17 Sep 2008 are not shown: on 17 Sep 2008 the price moved with no split, bonus or other action on record to explain it, so no figure is worked out across that day.

Splits, bonus issues and other changes

What the prices above are adjusted for, so they read as one share held throughout.Hercules Investments bonus and split history

Ex-date	Event	Price factor	What happened
11 Oct 2024	Demerger	0.2799	Part of the business became a separate company. The factor is the opening price on the ex-date divided by the previous close. The chart shows earlier prices with the demerger reinvested.
11 Jul 2012	Bonus	0.5000	Holders received 1 bonus share for every 1 held.
17 Sep 2008	Price move	–	Between two trading sessions the price fell 47% or more, or rose 90% or more. No corporate action is on record. Earlier prices are not shown.

Earlier prices are multiplied by the factor, so the chart reads as one share held throughout. Where an event has no factor that can be worked out, the chart leaves out the closes before it.
