The implied volatility you bought was good value, because a convertible can be split into a straight bond plus an embedded equity option; if that option’s market-implied volatility is lower than the volatility you expect to realize, buying the convertible and hedging away unwanted risks leaves you with a cheap option exposure that should earn a positive expected return.

Relevant concepts:
- Convertible decomposition: Convertible price ≈ straight bond value + call option on stock (conversion feature).
- Implied volatility: the volatility input that makes a pricing model (e.g., Black–Scholes-type) match the option price.
- Volatility arbitrage / delta-hedged option P/L: a delta-hedged option’s expected P/L depends on realized volatility vs. implied volatility and on the option’s vega/gamma.
- Hedging unwanted risks: delta-hedge the equity exposure, hedge interest-rate or credit exposures to isolate the volatility bet.

Step-by-step reasoning:
1. Decompose the security: Price(convertible) = Price(bond) + Price(call on stock). Market prices imply a call price, from which implied volatility (σ_imp) is derived.
2. If you can hedge out the bond/credit/interest-rate parts, you are left with the call option payoff.
3. A delta-hedged option’s expected P/L is roughly proportional to the difference between realized volatility (σ_real) and the implied volatility (σ_imp), scaled by the option’s vega: Expected P/L ≈ vega × (σ_real − σ_imp).
4. Example numeric illustration: suppose vega ≈ $50 per 1% vol, σ_imp = 30%, and you expect σ_real = 50%. Then expected P/L ≈ $50 × (50% − 30%) = $50 × 20 = $1,000 (over the relevant horizon), before financing/dividend costs.
5. If σ_real > σ_imp and hedges remove other risks, you expect to capture the volatility premium.

Why this is correct: Buying the convertible effectively buys the embedded option at the market’s implied volatility. If that implied volatility understates your expected realized volatility, the option is undervalued relative to your forecast, so a hedged position should be profitable.

Why other reasons would be weaker: alternative explanations like “high coupon yield,” “credit spread pick-up,” or “call protection” don’t by themselves justify buying converts if you can’t profit from the option component — the specific argument Bret emphasized was the relative cheapness of implied volatility. Those other factors either are smaller in magnitude or introduce risks that were supposed to be hedged away.

This confirms the provided answer: The implied volatility you bought was good value.

Convertible bonds have several distinct 'regions' which include all of these except:

A convertible bond is a regular corporate bond that has the added feature of being convertible into a fixed number of puts on common stock so there is protection on the bond. Convertible bonds are debt instruments because they pay interest and have a fixed maturity date.
