Nippon Life's sustained open-market accumulation at ~$34.86/share, well above the recent price, signals strong conviction. Monitor for a potential 13D amendment or further buying that could indicate strategic intent. The CIO's small sale is likely liquidity-driven and does not offset the 10% owner's bullish signal.
