How It Works
This professional-grade calculator identifies arbitrage opportunities in convertible bonds through comprehensive analysis of theoretical values versus market prices. The model employs sophisticated financial engineering principles while maintaining user-friendly implementation.
Core Components Analysis
- Conversion Value Calculation
Determines the equity value of the convertible bond by multiplying the current stock price by the conversion ratio. This represents the bond's immediate value if converted to equity, factoring in any conversion premium or discount.
- Bond Floor Computation
Calculates the straight bond value using:
- Credit-adjusted discount rates incorporating issuer's credit spread.
- Present value of future coupon payments.
- Terminal value at maturity.
- Yield curve considerations for accurate discounting. - Option Value Assessment
Evaluates the embedded conversion option using modified Black-Scholes framework:
- Volatility input for price movement potential.
- Time value decay analysis.
- Dividend adjustment for accurate forward pricing.
- Interest rate impact on option premium. - Market Factor Integration
Incorporates critical market variables:
- Credit spread dynamics affecting discount rates.
- Interest rate term structure.
- Dividend yield impact on forward values.
- Volatility surface considerations.

FAQ
How accurate is the theoretical pricing model?
The calculator employs industry-standard models incorporating credit spreads, volatility, and interest rates. While simplified compared to full-scale pricing models, it provides reliable indicators for relative value analysis. The model uses a modified Black-Scholes framework for option valuation and discounted cash flow analysis for the bond floor, making it particularly effective for comparative analysis across different convertible bonds.
How should I interpret and use the mispricing indicator?
The mispricing indicator helps identify potential arbitrage opportunities, but requires careful consideration of several factors:
1) Transaction costs including bond borrow fees and stock lending rates.
2) Margin requirements which affect position sizing and carrying costs.
3) Liquidity constraints.
in both the convertible bond and underlying stock,
4) Market impact costs for larger positions.
Positive values indicate the bond trades above theoretical parity, suggesting a potential short opportunity, while negative values might indicate long opportunities.
What market factors most significantly affect the option value?
The option component's value is influenced by multiple factors:
1) Stock price volatility - higher volatility increases option value due to greater upside potential.
2) Time to maturity - longer duration typically increases option value due to more time for favorable price movement.
3) Moneyness - how far the conversion price is from current stock price affects delta and gamma.
4) Interest rates - higher rates generally increase option value through the carry component.
5) Dividend yield - higher yields typically reduce option value by decreasing the forward price.
How should I approach delta hedging with convertible bonds?
Delta hedging convertible bonds requires dynamic management due to changing market conditions. Start by calculating the bond's delta (conversion ratio × stock delta) and hedge accordingly with the underlying stock. Consider:
1) Gamma risk - larger price moves require hedge adjustments.
2) Credit spread changes affect optimal hedge ratios.
3) Volatility changes impact delta calculations.
4) Transaction costs from frequent rebalancing. Many traders maintain slight delta biases based on their market view while still capturing volatility premium.
What role does credit spread play in convertible arbitrage?
Credit spread impacts convertible bond pricing in several ways:
1) Direct effect on the bond floor through discount rate adjustment.
2) Influence on optimal hedge ratios due to changed default risk.
3) Impact on conversion probability and option value.
4) Relationship with stock volatility and general market conditions. Traders often use credit default swaps (CDS) or corporate bond positions to hedge credit exposure while maintaining equity optionality.
How do you determine appropriate position sizes in convertible arbitrage?
Position sizing depends on multiple risk factors:
1) Liquidity in both bond and stock markets.
2) Credit quality and potential jump risk.
3) Volatility exposure and gamma profile.
4) Margin requirements and funding costs.
5) Portfolio-level considerations including sector exposure and correlation with other positions.
Generally, more liquid positions with tighter credit spreads can support larger allocations, while maintaining adequate diversification across issuers and sectors.
