In Kentucky, Governor Andy Beshear estimated the death toll at 80 and talked about one twister that tore across 227 miles (365 km) of terrain, almost all of which was in Kentucky. So Newsome noted that while tornadoes can typically result in hundreds of millions of dollars worth of claims, "this could be a lot more." While the event was usual, Newsome suggested that it may be another data point indicating that increasingly unpredictable and unusual weather event may now be a permanent issue that insurance investors must consider. read more U.S. President Joe Biden said on Saturday it was likely to be one of the largest Tornado outbreaks in U.S. history and that he would ask the Environmental Protection Agency and others to take a look at whether climate change was a factor. read more Looking at 2020 data for auto, commercial, home owner and auto passenger insurance, the analyst estimated that State Farm has the biggest exposure to the affected states with 22% share of the market followed by Allstate Corp (ALL.N) at 8%, Liberty Mutual at 5.2%, Progressive (PGR.N) at 4.7% and Farmers insurance at 4.6%.

(Sinéad Carew) ***** WALL STREET HITS THE SLOPES AFTER HINT OF A LIFT (0958 EST/1458 GMT) After stock futures hinted at a pale green start to the week, Wall Street defied those expectations on Monday by heading lower after the opening bell. The three major U.S. stock indexes appeared to be cooling their heels after S&P 500 hit a record closing high on Friday and notched its best biggest weekly percentage gain since February Tesla Inc (TSLA.O), Microsoft Corp (MSFT.O) and Amazon.com (AMZN.O) weighed heaviest, with Apple Inc (AAPL.O) bucking megacap tech-plus trend following a target price hike from JPMorgan.

(0900 EST/1400 GMT) Despite less than stellar breadth readings on Friday along with the S&P 500"s (.SPX) fresh record-high close read more , the Nasdaq New High/New Low (NH/NL) index, has made a constructive turn: This measure of internal strength may have become sufficiently washed out with the Nasdaq"s (.IXIC) recent weakness. After falling to 12.5% on December 6 read more , which was its lowest reading since early-April 2020, the NH/NL index has now risen four-straight days. In so doing, this measure ended Friday at 21.1% which put it above its descending 10-day moving average, at 19.5%, for the first time since November 12. read more It now remains to be seen if last week"s sharp NH/NL index upturn from especially depressed levels will lead to the broader Nasdaq re-heating, and therefore, fuel a more sustained IXIC rise. Indeed, there certainly is room for the NH/NL index to rise before it will encounter resistance lines from its highs earlier this year. The measure"s early November peak was at 75.7%. Of note, current readings on the NYSE show a similar picture as the Nasdaq. After also falling to its lowest level since early-April 2020, the NYSE"s measure also ended Friday above its 10-DMA. A Nasdaq NH/NL index violation of its Dec. 6 low can open the door for a test of its March 2020 trough at 1.2%, something which could put the IXIC on ice.
