Professional Experience


Academic History

  • O’Shea became interested in the market when he read Reminiscences of a Stock Operator aged 17.
  • He was featured in Jack Schwager’s Hedge Fund Wizards. His chapter is called “Knowing When It’s Raining”.
  • He doesn’t trade single equities, though he does trade equity indices.
  • He uses stop losses, but relatively wide ones.
  • He uses a return/risk measure he calls “Gain to Pain Ratio,” the sum of all monthly returns divided by the absolute value of the sum of all monthly losses.
  • He says that the genius of Soros was his timing – knowing when to put on the “obvious” trade.
  • He won’t take a position until he can see the trend.
  • He believes that 90% of macro investing is implementation and flexibility. 
  • He says that Soros has the least regret of anyone he has met – he has no emotional attachment to his trades.
  • He uses the controversial Value at Risk as a risk measure, an amount of loss within a specified time period to a given level of confidence (usually 95% or 99%).
  • During the 2008 crisis, he used option straddles and strangles to “buy” FX volatility. He also bought short-term bonds and shorted long-term bonds, expecting the flat yield curve to steepen. In addition, he bought credit default swaps, expecting the yield on corporate bonds to increase more than that on Treasuries.
