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. Mr Cawkwell credited his co-author with the penname Evil Knievil. The plan worked to the tune of £250,000, and the nickname stuck.
