Anyone knows if the historical data provided by Zerodha is adjusted (for splits/bonus/demerger/etc)? What is the earliest date from which the data is available.
We adjust historical data for corporate actions to improve analysis. Adjustments are made for bonuses, splits, rights issues, spin-offs, and extraordinary dividends. You can find a similar discussion here.
We adjust as soon as we receive the Cost of Acquisition (COA) for the particular script. The adjustment for this script has already been done, and you can verify it in a similar discussion on our TradingQnA post here.
