Trading looks like it is picking up for climate control firm Andrews Sykes (ASY:AIM) and could be set for another boost if July’s hot weather continues.

Office air conditioning units were straining under the warmest July temperatures on record earlier this month, hitting up to 36.7C at Heathrow airport. Commercial demand for additional, temporary or replacement systems could prove a further catalyst at results scheduled for 28 September.

Sykes’ stock is still trading 9% lower than before a half-year update in September 2014 which said adverse weather conditions and a slowdown in Benelux construction markets would impact full-year profits.

Most of the profit shortfall in the year to 31 December 2014 came in the first half. Second half operating profit was down 15.7% year-on-year, compared to 32.3% in the first half.

Ninety-five-year-old chairman Jacques Gaston Murray said trading in the fourth quarter was only marginally behind the same period in 2013, indicating performance is starting to improve - as well as lap softer prior year comparisons.

Sykes is 86% owned by family investment vehicle EOI Sykes Sarl, so it has a limited free float. Potential investors also have a wide bid-offer spread to contend with, at 4.3%, and a lack of liquidity in the stock - all of which are additional risks to consider.

No analysts cover the stock and we have been unsuccessful in the past at securing an interview with management.

A high quality business. Buy at 340p.
