Mobility of capital coupled with no liability for shareholders means that many short-term plays can be theoretically more profitable (in fact, in face of lack of profit-sharing schemes etc, trading stock is going to be main source of profit), and decouple you even further from possible risks.

This is the basis of how considerable portion of financial markets operate, with total reduction to "game of numbers" being the ultimate form of capitalism - i.e. capital making more capital.
