Discuss relative value hedge fund strategies: their investment features, how they are put into practice and the role they play in a portfolio

Relative value funds profit from mispricing between related securities, usually hedging out broad market direction and using leverage because the spreads are small. Fixed-income arbitrage exploits anomalies such as yield curve kinks, on-the-run versus off-the-run bonds, swap spreads or carry trades; leverage can be very high and positions suffer when liquidity dries up. Convertible bond arbitrage buys convertibles whose embedded options look cheap and shorts the issuer's shares in proportion to the option's delta, earning coupon income and trading gains around the hedge. The number of shares to short is N = delta × conversion ratio × number of bonds, and it changes as delta does. The portfolio role is low-correlation income, but losses cluster in crises when credit spreads widen and borrowing stock gets hard. The trap is treating these trades as riskless.
