HotSpot FX is not a household name, but for some of Wall Street's biggest banks it is a currency trading firm of vital importance. The New Jersey business is backed by Lewis, 67, one of the world's great currency traders. After making his first fortune in the London restaurant trade, Lewis moved into foreign exchange and equities, dealing from a base in the Bahamas in the late 1970s. The Tavistock Group, his main investment vehicle, is valued at more than £1 billion on the strength of holdings in the energy, property, industrial and financial service sectors. He also owns 7,000 valuable acres in Orlando, Florida, and has extensive Russian oil investments.
