I doubt this. The increase in liquidity seems to me insufficient to explain
the extent of the common rise in price. However, I admit I don't have any
hard evidence.
A more plausible explanation for the post-split rise in stock price, it
seems to me, is that investors see the split as a sign of management's
confidence in future earnings.
