Boyle began his career in Finance working for Bank of America in BostonMassachusetts, where he began his initial research into the behavior stock prices. At Bank of America he realised that the biggest difficulty he faced was that he lacked experience. With the new availability of online market data in the public domain at the end of the 1990s, Boyle started to study markets. "I thought it might be a smart approach if I analysed as much data as possible so I could speak knowledgeably about stocks; even if I hadn’t lived through the various market periods, I could at least be a history student of the market." Boyles studies became more statistical in their nature and he enjoyed a couple of early successes, applying his theories to investment. "I realised over time that certain rules work better than others" he says. "I initially approached the markets like a man from Mars who knewnothing at all and in a way that is why I developed my own approach." He read about Victor Niederhoffer, admired his statistical approach and began corresponding with Niederhoffer sharing his statistical studies as to how markets behaved. Niederhoffer liked what he saw and made Boyle a job offer. In 2001 he began working for Victor Niederhoffer, a former partner of George Soros' as a financial derivatives trader. Boyle has since been a Portfolio Manager at Royal Bank of Scotland Group, Millennium Management, LLC and Nomura Securities. Boyle founded Palomar Capital Management, a multi award-winning hedge fund in 2011 along with his business partner Jesse McDougall. At Palomar, Boyle wrote computer code that enters hundreds of trades a day in global markets that has a win rate of 65%. Investors in Palomar include Stanley Fink, Larry Hite and Victor Niederhoffer.
