Insurance stocks hitting 52-week highs on rate tailwinds

Property casualty names like TRV and AIG are breaking out while life insurers finally catching a bid on higher reinvestment yields. Is this the most underowned sector rotation play, or are we missing something on the claims cycle?

This is classic duration mismatch unwinding - P&C insurers were sitting on massive unrealized losses when rates spiked, now they're printing money on float reinvestment. My base case is this runs another 6 months until the yield curve steepening trade gets crowded.
