Spread betting is a form of derivative trading, where you do not have to actually own the asset that is underlying the trade that you are conducting. As a spread bettor, your work will be guessing or rather speculating on whether the asset under consideration will fall or rise in value. Spread betting was invented by a mathematics teacher who later became a securities analyst, by the name of Charles K. McNeil. However, spread betting is not allowed in the USA, until certain legislation can be put in place in order to regulate the trade.
