Assuming that sound fundamental investing would be to buy good companies at relatively low price to
their intrinsic value, why then don't the management of such companies like RXP with 13 millions in cash, and very solid cash flow do not exercise share buy back when the share price of their own company is at a ridiculously low price, instead of looking for bargain M&A somewhere else, purchase your own shares and
enjoy the fruits and good fortune of having such low share price . it is a golden opportunity to raise the ROE
for share holders in a fairly straightforward manner, and no risks.
