Well prices are generally based on supply & demand, & seeing as a stock split would increase the supply of the shares, then the price would drop unless demand increased at the same rate.
Anyway what does it matter, unless you happen to be planing to sell your shares on a certain day its irrelenvant what price they are trading at the stock exchange on that particular day.
I have about $8000 worth of Telsta shares & I personally don't give a fuk what there valued at, as I have no intention of selling, while they keep making record multi-billion dollar profits every year. BTW, their shareprice is really pissy right now, but what does it matter unless I'm buy or selling Telstra shares today.
Unless of course you're planing on useing them as collateral on a loan.
