yeah that was my initial direction with home insurance companies first...I still think the insurers are going to be impacted by this event negatively, IMO...Damages are estimated to be north $18B 2nd highest in TX. Most of the claims are going to be related to water damages i.e. dominated by water claims. Based on those estimates this puts them on the 2nd costliest catastrophe, next to huricane Ike in 2008 the damage costs were a whopping $21.5B according to these guys https://www.iii.org/
Of the top insurers, StateFarm is the leader in Texas, then Allstate. at least on my part i'm not able to see their prices on an incline for the time being because typically in the immediate term, insurers price of the stock declines, normally because the damages are assessed and insurers EPS's are adjusted downward for the next few weeks, months but once the payout claims begin to kick in then their premium begins to rise and the stock price tends to rise along reaching higher highs.
With this winter storm impact, besides Texas, hardest hit states include, Arkansas, Missouri, Oklahoma and Tennessee .I personally don't have analysis on these states in terms insurers market share...but it may be worth a look. let's say (hypothetically speaking here) Statefarm is a dominant player in all of the hardest hit states, than that will move the needle for the stock IMO once the payout claims begin to kick and the rebound etc.
