PUNT OF THE WEEK

WHAT IS IT? Based in Florida and listed on AIM, Somero Enterprises supplies 99pc of the world’s laser screeds – industrial devices that lay flat, level floors for warehouses far quicker than is possible by hand.

WHAT’S THE LATEST? Shares have more than tripled since 2015, driven by demand for warehouse space from internet retailers such as Amazon.

WHO BACKS IT? Top shareholders include Canaccord Genuity, Artemis Investment Management and Close Brothers Asset Management.

WHY YOU SHOULD INVEST Thomas Becket, chief investment officer at Psigma Management, says: ‘The company is a play on the global non-residential construction market and if you believe this will remain strong for the foreseeable future, Somero should be a beneficiary.’

AND WHY YO U SHOULDN’T Somero’s success depends on a robust global economy and free trade – and with rising United States protectionism and uncertainty over Brexit, there are growing concerns about both. Any new tariffs or barriers are likely to hit the warehousing market and make a dent in the firm’s share price.
