As usual the reverse split of the stock and the adjustment of prices and volumes to post-split figures downloaded into Quicken doesn't jibe with reality, requiring some editing of the price history for the stock for a period of time before the split.
For whatever reason Yahoo Finance has NOT made the split adjustment for the period of July 19 - July 30, i.e., they are showing the old "before split" numbers, but have adjusted everything for dates before the 19th.
This makes it relatively easy to correct the incorrect downloaded information in Quicken which roughly uses those same dates. I expect that the Yahoo numbers will be changed fairly soon to the post split figures, so act fast.
