In the event of a stock split Stockpools will multiply the starting price for
that company by the inverse of the split ratio. For example, suppose a company
undergoes a 2-for-1 split with a starting price of $10. After the
split takes place that company's new starting price would be $5. We arrive at
this price by multiplying $10 by 1/2 (the inverse of 2:1). The same process is
undergone for reverse splits/rollbacks.
