Evil Knievil is the betting name of accountant Simon Cawkwell, 55. Operating from his South Kensington home, he identifies firms whose shares he thinks are overvalued, then bets the price will fall. He reckons to earn 'a thick six-figure sum' every year, although he has had his share of upsets. His nickname comes from one of his best-known exploits, when he spotted the weaknesses in Robert Maxwell's firms, bet on their share price dropping, and wrote a report to send round the City the next day. Cawkwell credited his co-author with the pen-name Evil Knievil. The plan worked to the tune of £250,000, and the nickname stuck.
