These events were road races in all but name, but in Italy such races were still allowed, and the Mille Miglia continued until a serious accident in 1957 caused it to be banned.[43] Meanwhile, in 1981, the Tour de France was revived by the Automobile-Club de Nice as a different kind of rally, based primarily on a series of races at circuits and hillclimbs around the country.[44] It was successful for a while and continued until 1986. It spawned similar events in a few other countries, but none survive.
Rising investor confidence also indicates a rally, and it is perhaps more powerful than any economic indicator because when investors believe something is going to happen (a rally, for example), they tend to take action (purchasing shares in order to profit from expected price increases) that actually turn expectations into reality. Although it is an objective concept, investor sentiment shows through in mathematical measurements such as the put/call ratio, the advance/decline line, IPO activity, and the amount of outstanding margin debt.
