Yahoo finance provides Adj close prices which are prices adjusted for splits and dividends. What about the open price?



1 Answer 1


For the raw data, the open, high, and low price are not adjusted. They are they actual prices at which the stock trades pre and post dividend.

The adjusted close price is just what it says, an adjustment of the close, done so to take into account all distributions so that one can calculate the total return on the investment.

The exception to this is data for charting programs. In this case, all of the data prior to the special dividend is adjusted so that there isn't a large gap on the chart, destroying the ability to do technical analysis.

  • It's worth noting that all dividends and splits happen overnight, so the open, high, and low on each day can be multiplied by the same ratio (adjusted close divided by close) to give a full adjusted daily candle.
