  2. Option-adjusted spread - Wikipedia

    en.wikipedia.org/wiki/Option-adjusted_spread

    The embedded "option cost" can be quantified by subtracting the OAS from the Z-spread (which ignores optionality and volatility). Since prepayments typically rise as interest rates fall and vice versa, the basic (pass-through) MBS typically has negative bond convexity (second derivative of price over yield), meaning that the price has more ...

  3. Z-spread - Wikipedia

    en.wikipedia.org/wiki/Z-spread

    The Z-spread of a bond is the number of basis points (bp, or 0.01%) that one needs to add to the Treasury yield curve (or technically to Treasury forward rates) so that the Net present value of the bond cash flows (using the adjusted yield curve) equals the market price of the bond (including accrued interest). The spread is calculated iteratively.

  4. Yield spread - Wikipedia

    en.wikipedia.org/wiki/Yield_spread

    The "yield spread of X over Y" is generally the annualized percentage yield to maturity (YTM) of financial instrument X minus the YTM of financial instrument Y. There are several measures of yield spread relative to a benchmark yield curve, including interpolated spread , zero-volatility spread , and option-adjusted spread (OAS).

    option-adjusted spread, or the extra yield demanded by the security holder to compensate for the mortgage repayment option; current-coupon spread; volatilities; convexity; cost of carry; While all these factors can be important in accounting for changes in MBS returns, in practice a particular user may only select a subset.

  8. Talk:Option-adjusted spread - Wikipedia

    en.wikipedia.org/wiki/Talk:Option-adjusted_spread

    OAS is not just over the treasury curve. Increasingly the swap curve is used. And in practice, people build a curve of securities from the same issuer. For instance, they compare a callable Fannie Mae against the curve built from Fannie Mae bullets. That's comparing apples with apples. —141.228.106.136 at 17:04, 3 February 2009.

  9. Bond convexity - Wikipedia

    en.wikipedia.org/wiki/Bond_convexity

    In finance, bond convexity is a measure of the non-linear relationship of bond prices to changes in interest rates, and is defined as the second derivative of the price of the bond with respect to interest rates (duration is the first derivative).
