Soros is one of the world’s most famous speculators - who sees the market as something to place highly leveraged bets on rather than invest in.
He cemented his reputation by shorting the pound on Black Wednesday in 1992, and making $1 billion from the collapse of the British currency and the near-collapse of the Bank of England.
He is another noted philanthropist, giving primarily to human rights, public health and education charities.
Slater was another highly controversial investor, known for corporate raids on public companies, and subsequent asset stripping to realise quick value for shareholders.
He also invented the phrase ‘The Zulu Principle’ to describe the importance of being a specialist when you are investing, so you can concentrate your research efforts and know more than the rest of the market about something specific.
Woodford (CBE) gained his reputation at the helm of the Invesco Perpetual Income and High Income funds, by offering relative stability and reliability in even the toughest markets.
His trademark was to make bold decisions about the companies he wanted to be invested in, and then stick with them - no matter how unfashionable his decisions were.
It led him to buy tobacco stocks in the 1990s (because he felt that concerns about the legal threats to the firms were overplayed) and avoid technology in the dotcom bubble.
Woodford currently runs Woodford Investment Management.
