Expert Tip

Conversion parity is the equity equivalent value; buying the bond makes sense if it trades close to or below parity.

How this Calculator Works

This calculator computes the parity price and conversion value of a convertible bond, which can be exchanged for common stock shares of the issuing company. It helps arbitrage traders identify whether a bond is trading at a premium or discount compared to its stock equivalent.

Formula & Methodology

Conversion Value = Stock Price * Conversion Ratio - Stock Price is the current trading price of the company's common stock. - Conversion Ratio is the number of shares received per bond conversion.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

A company's stock trades at $45 per share. Each convertible bond offers a conversion ratio of 20 shares per bond. 1. Multiply stock price by conversion ratio: $45 * 20 = $900. Result: The conversion value of the bond is $900.

FAQ

How does bond duration measure interest rate risk?
Modified duration estimates the approximate percentage change in a bond's price for a 1% (100 bps) shift in interest rates. Higher duration indicates greater price sensitivity to rate moves.
What is Tax-Equivalent Yield (TEY) for municipal bonds?
Tax-Equivalent Yield = Municipal Tax-Exempt Yield / (1 - Marginal Tax Rate). It shows the pre-tax yield a taxable bond would need to equal the after-tax yield of a tax-free municipal bond.
Can fixed income calculators guarantee bond trading outcomes?
No. Bond pricing models assume clean compounding yields and fixed reinvestment rates. Secondary market prices fluctuate based on liquidity, credit rating revisions, and market interest rate movements.
