Poland’s Purchasing Managers’ Index (PMI) fell to 52.7 points in May from 54.1 points in April, according to Markit, a provider of financial information services.

The reading, however, suggests optimism in industry.

A neutral PMI rating of 50 means that businesspeople in the country feel that the economy will not change over the coming month.

A higher rating means that it is expected to improve, while a PMI rating below 50 indicates that many think it will deteriorate.
