Question

What is yield-to-worst (YTW), and why is it used for HY bonds instead of YTM?

Answer

Yield-to-worst is the lowest yield an investor can receive across all permitted redemption scenarios, assuming no default.

For a callable bond:
```
YTW = min(YTM, yield to first call, yield to later calls, yield to put if applicable)
```

A HY bond priced at 105 with 7% coupon may have 6.2% yield to maturity but only 5.5% yield to first call. YTW is 5.5%.

HY issuers call bonds when refinancing is favorable. Investors therefore focus on the worst economic call scenario. YTM can overstate expected return if the bond is likely to be called early.

IG bonds are often discussed on YTM / spread basis; callable HY bonds are typically priced on yield-to-worst.
