第二季度PPNR未能上市后，美国运通股价下跌

American Express (NYSE:AXP) stock fell 2.6% in Friday midday trading as the credit card company's core pre-provision net revenue (NNPR) fell short of Wall Street expectations. New card acquisitions also slowed during the quarter.

The stock initially rose in premarket trading soon after American Express announced Q2 earnings and revenue that beat the average analyst estimate.

Citi analyst Keith Horowitz said core NNPR of $4.96B came in under his estimate of $5.03B, an equivalent of an 8-cent-per-share miss and a 3-cent miss compared with the consensus.

He also noted that new card acquisition growth slowed to 3.1M from 3.3M.

"We estimate NNA (net new account) growth of ~3%, which is slower than LTM (last 12 months) run rate of ~4%," Horowitz wrote in a note to clients.
