Reviewing cost basis on HPQ (9/24/98, specifically). There is an inconsistency between the two sites and I wanted to see if anyone could explain why there is.
Yahoo finance says $17.14, Google says $26.69.
Yahoo has an footnote saying
* Close price adjusted for dividends and splits.
I'm assuming Google adjusts for splits, but maybe not dividends? What does adjusting for dividends mean anyways?
