RT Journal Article SR Electronic T1 Risk in Fixed-Income Hedge Fund Styles JF The Journal of Fixed Income FD Institutional Investor Journals SP 6 OP 27 DO 10.3905/jfi.2002.319321 VO 12 IS 2 A1 William Fung A1 David A. Hsieh YR 2002 UL https://pm-research.com/content/12/2/6.abstract AB The authors apply principal components analysis to groups of fixed-income hedge funds to extract common sources of risk and return. These common sources of risk are related to market risk factors, such as changes in interest rate spreads and options on interest rate spreads, or asset-based style factors (ABS). The conclusion is that fixed-income hedge funds tend to be exposed to a common ABS factor, credit spreads.
