21. Fixed Income Arbitrage • Fixed Income Arbitrage managers are trying to capture spreads and positive carry in various forms, from simple strategies to more complex ones: • Emerging market credit spread - the managers try to time exposure to EMD spreads (duration hedged spread against US treasury), with bias towards being long the spread • Mortgage-backed securities - similar to EMD spreads, the managers are biased towards capturing the spread between MBS/ABS/CMBS and US treasuries by applying models for calculating prepayment risk (the option embedded in MBS). They tend to take the exposure in the less liquid/traded CMO trenches were they think mis-pricing of the prepayment option exists • Volatility trading - the managers take views on volatility and skews and are biased towards being short options and collecting the difference between implied and actual volatility • Carry/yield curve trades - try to capture positive carry (the difference between cash and longer-term rates) and implement views on the shape of the yield curve applying interest-rate models.  These views are applied to the short-end of the curve (Euro$) and the long-end (Bonds) • Currency - managers take some active views on currencies, primarily based on interest rate diffs between countries
