Split not accounted for in historical prices for 18ME.DE
18ME.DE underwent a 300:1 split a couple months back. Historical prices were not adjusted so e.g. year to date performance shows a 99.6% loss in value. My understanding is that you should retrospectively modify historical prices after a split, e.g. GOOG underwent a few splits including one recent one (this or last year?) and there is no such problem with its historical price.
