Why Edison International Stock Just Crashed

EIX crashed 24.2% after California lawmakers rejected Governor Newsom's wildfire liability shield proposal. The defeated legislation would have barred insurance companies from filing subrogation lawsuits against utilities for wildfire damages, forcing insurers to absorb those costs instead. The collapse of the main protection measure triggered Mizuho Bank to downgrade the stock.

The legislative failure leaves EIX exposed to potential billions in claims from insurers seeking to recover wildfire payouts. Without subrogation protection, utilities remain on the hook when their equipment is found to have sparked fires, even if some compromise measures remain under discussion. The 24% single-session drop reflects trader concern that California's wildfire liability framework will continue to impose uncapped risk on the state's investor-owned utilities.

Mizuho's downgrade followed immediately after the vote, signaling Wall Street's view that the regulatory environment has deteriorated materially for the sector.
