On this episode of Stock Movers:

- Cooper (COO) shares tumble 14% postmarket after the healthcare supplies maker cut its adjusted earnings per share and revenue guidance for the full year. The firm’s fourth-quarter profit and revenue forecasts also fell short of Wall Street’s expectations.

- Macy's (M) shares sink. The company’s third quarter guidance left investors unimpressed, overshadowing a strong quarterly performance and increase in outlook. The company’s bottom end of comparable sales and sales guidance is below analysts estimates but the top line is ahead. Macy’s adjusted diluted earnings per share guidance is also below estimates.

- American Eagle (AEO) shares drop. The apparel firm’s second-quarter total comparable sales fell short of the average analyst estimate. Analysts note that strength at its aerie brand was more than offset by weakness at AE.
