The services sector index fell 5.3 percent to 92 in the month, from 97.1 in April.
“This decrease in the services confidence index stemmed from the lower number of managers evaluating the ‘business situation’ as having improved and the higher ‘demand-turnover’ over the past three months, as well as the expected increase in ‘demand-turnover’ over the next three months,” TSI stated on May 25.
The retail trade confidence index was down 3.2 percent month-on-month, reaching 97.1 in May from 100.3 in the previous month.
“This downswing in the retail trade confidence index resulted from the lower number of managers evaluating improved ‘business activity-sales’ over the past three months and ‘current volume of stock’ as below normal for the season, as well as the expected improvement in ‘business activity-sales’ over the next three months,” TSI added.
The construction sector confidence index also fell 2.1 percent to 77.2 points in May from 78.8 in April.
“This decrease in the construction confidence index stemmed from the lower number of managers evaluating ‘current overall order books’ as above normal for the season and the expected increase in ‘total employment’ over the next three months,” TSI stated.
Sectoral confidence indices range from 0 to 200, indicating an optimistic outlook when above 100 but a pessimistic outlook when below 100, according to TSI.
