The humiliating volte face does, however, hit the venture capital industry and the investment banks. The ethos of venture capital is that it can turn its investments over quickly - it can go into a business, streamline it, gear it up with debt, make one or two logical acquisitions and sell it on to the investing public. But if the final buyer is not there, if the private equity funds are deprived of their exit, they are very quickly in trouble. The longer they hold an investment, the less attractive the rate of return it generates and the less easy it is for them to attract the new funds.
