In that light, it is worth highlighting a few UK companies whose attractions today may well be greater than they were six months or a year ago. And I don’t mean would-be ARM lookalikes such as Imagination or Laird.
What I mean is quality Brit companies with that edge, product or technology that makes them different. Vodafone is an obvious example, with a world-leading position in European mobile. It must look attractive to a US rival wanting to add pounds and euros to its revenues.
Credit-rater Experian, which earns mainly in dollars, could catch the eye of a foreign buyer.
Burberry and SuperGroup must surely fire the ambitious spreadsheets of a bigger, probably European, luxury brands house.
But for a real Brexit-fuelled takeover punt, why not pick up a few shares in ITV? It is less and less driven by UK advertising and more and more by content, most of which is sold in dollars.
