The pitfalls have proved particularly dangerous in the industry we mentioned. It was, of course, easy to forecast that the volume of air traffic would grow spectacularly over the years. Because of this factor their shares became a favorite choice of the investment funds. But despite the expansion of revenues—at a pace even greater than in the computer industry—a combination of technological problems and overexpansion of capacity made for fluctuating and even disastrous profit figures. In the year 1970, despite a new high in traffic figures, the airlines sustained a loss of some $200 million for their shareholders. (They had shown losses also in 1945 and 1961.) The stocks of these companies once again showed a greater decline in 1969–70 than did the general market. The record shows that even the highly paid full-time experts of the mutual funds were completely wrong about the fairly short-term future of a major and nonesoteric industry.
