Analysts spend thousands of hours trying to mathematically determine what will trigger the next rally and how long it will last. Technical analysis is especially prevalent in this effort, although less sophisticated indicators such as hemline fashions or the NFL division of the latest Super Bowl winner also provide fodder for such predictions. This in turn can sometimes lead to speculation that a rally is just around the corner, which can then become a self-fulfilling prophecy.
As public interest grew, car companies started to introduce special models or variants for rallying, such as the British Motor Corporation's highly successful Mini Cooper, introduced in 1962, and its successor the Mini Cooper S (1963), developed by the Cooper Car Company. Shortly after, Ford of Britain first hired Lotus to create a high-performance version of their Cortina family car, then in 1968 launched the Escort Twin Cam, one of the most successful rally cars of its era. Similarly, Abarth developed high performance versions of Fiats 124 roadster and 131 saloon.
What do you do when you're Mercedes-Benz in the late 1970s and you want to go rallying, but your sportiest car is a luxury cruiser that isn't very sporty? You take the C107 SLC Coupe rallying anyways. In an era dominated by nimble cars like the Lancia Stratos and Ford Escort, the 450SLC must have been quite a sight, but Mercedes actually had some competition success. Mercedes won the 1978 South American rally and was able to get 4th place in a Manufacturers Championship.
In Africa, 1950 saw the first French-run Méditerranée-le Cap, a 10,000-mile (16,000 km) rally from the Mediterranean to South Africa; it was run on and off until 1961, when the new political situation hastened its demise. In 1953 East Africa saw the demanding Coronation Safari, which went on to become the Safari Rally and a World Championship round, to be followed in due course by the Rallye du Maroc and the Rallye Côte d'Ivoire. Australia's Redex Round Australia Trial also dates from 1953, although this remained isolated from the rest of the rallying world.
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.
