(ShareCast News) - Esure's plans to de-merge Gocompare, its price comparison website, makes sense, the Financial Times's Lex column said. "There is trapped value there," Lex added.Insurance companies are all about managing risk and are sustained on capital, whereas the website is a wholly different animal, it is a digital marketing concern, requiring constant operational expenditures.Indeed, even at 15 times earnings, Gocompare would be able to fetch a valuation of about £500m, leaving Esure trading on about eight times profits versus competitor Direct Line's multiple of 13 times earnings, Lex pointed out.Furthermore, Esure's operating costs were at a respectably low 24% of premiums and it made big profits from "non-underwritten additional services".Esure's combined ratio of claims and costs to premiums had also only risen past 100% - indicating losses - just once in the past six years.Management believes it can boost its performance by increasing its market share during a benign phase of the pricing cycle and maintaining high retention rates.It can probably pull off the trick, "but it will have less of a safety net if it fails," Lex concluded. The Times' Tempus column is urging caution towards investing in airline group International Consolidated Airlines Group (IAG), as it battles with a weaker pound and uncertainty around the British economy.Robert Lea says the dominant airline at London Heathrow has limited space to grow at that hub, and combined with an expected aviation market slump on the back of shrinking gross domestic product in the UK, it's better to stay well away."People will keep flying but they will expect to fly cheaper: not good news for airline profit margins," asserts Lea."Brexit means that suddenly BA's strategy is not based on a UK economy that will lead Europe out of recession; it is now an airline based in a UK economy expected to be as moribund as the rest of Europe."Along with its minority carriers Iberia and Aer Lingus, IAG is in dire need of a strategy update, Lea said, referencing research from RBC Capital Markets analyst Damian Brewer.Competition on short-haul routes is stiffening and there is better service and product on offer on the long-haul ones, Brewer pointed out.The devaluation of the pound has certainly not helped the group's fortunes either, contributing to the shares trading on just six or seven times earnings."Low, but for a reason," Tempus says.The tipster adds that it "has not been convinced by IAG in the past" and is "even less so now".As a result of this all-round uncertainty, Tempus says "avoid" IAG.
