It isn’t often that a completely new business category opens up. But, when it does, it almost always begins and ends in the same way. Take the dotcom bubble as an example. In the late 1990s, U.S. technology stocks soared as investors drove up stock equity valuations of internet-based companies. By 2000, however, the bubble began to burst, leaving investors’ pockets empty from investing in “can’t fail” new technologies.
