Really good point Howard. It appears to mean that stats generated from testing a system on data flawed in the ways you describe must be dubious. But no-one seems to have ASX data that isn't adjusted for splits or with the dividends adjusted into the share price. I've seen the Blackstar study and agree it would be far nicer to have this kind of data to test with (not to mention a CPI adjusted liquidity filter...this is obviously far easier to do). Without this kind of data, what do you do? This could be yet another reason why the big boys don't play in this part of the market..the Aust market isn't big enough to warrant fixing 22 years of data for testing systems like what the Blackstar guys do in the US.
