A friend asked me about this privately, so let me explain it in plain English.
Before maturity, equal amounts of PT and YT can be combined to recover the original yield-bearing asset.
The price of YT is essentially a quote for future yield: if the actual yield received before maturity is lower than the market’s expected yield when you bought it, YT holders will lose money.
$PENDLE is the native token of the yield tokenization protocol Pendle.
Did you misunderstand this too at some point?
