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.

The company also lowered its financial outlook for the fiscal year ahead, projecting earnings per share between $20 and $21 versus its prior range of $20 to $22. That sent shares tumbling nearly 15%.

Andrew Graham, managing partner at Jackson Square Capital, shares his take on FedEx's latest financial results and its prospects. The Memphis-based company cut the top end of its full-year profit outlook and reported quarterly earnings below expectations on softer demand for package deliveries.
