The shipping carrier is calling out a growing trend that speaks volumes about the current state of the industrial economy.

FedEx said a weaker industrial economy produced a “challenging” quarter that caused it to trim its outlook for later this year, a sign of possible cooling in the wider economy.

FedEx reported a steep quarterly profit drop and lowered its full-year revenue forecast on Thursday after its customers continued to trade down from speedy, pricey delivery to cheaper, slower options.

In trading on Friday, shares of FedEx crossed below their 200 day moving average of $267.52, changing hands as low as $255.40 per share.
