Check out the companies making headlines before the bell:

Nike (NKE) – The athletic footwear and apparel maker was upgraded to “buy” from “neutral” at Goldman Sachs and added to the firm’s “Conviction Buy” list. Goldman believes Nike is on the verge of a sharp acceleration in earnings growth, with China being a key driver.

Dollar General (DG) – The dollar store operator beat estimates by 4 cents a share, with quarterly profit of $1.42 per share. Revenue also beat estimates. Comparable-store sales were up 4.6%, compared to the 3.3% estimate of analysts surveyed by Refinitiv.

Apple (AAPL) – Citi reiterated its “buy” recommendation on Apple and raised its price target on the stock by 20%, to $300 share from $250 a share. Citi expects sales and earnings to increase more than the Street generally expects, and thinks the demand for the Apple Watch and AirPods is underappreciated.

Chewy (CHWY) – The pet products seller was upgraded to “overweight” from “equal-weight” at Morgan Stanley, which thinks the stock has an attractive entry point after a 24% pullback. The firm said it likes Chewy’s position as the No. 1 online pet products seller in a market experiencing secular growth.

Express (EXPR) – The apparel retailer posted an adjusted third-quarter loss of 3 cents per share, smaller than the 9 cents a share loss expected by analysts.

Revenue beat estimates, and comparable-store sales were up 2.1%. Analysts surveyed by Refinitiv had expected a 1.3% drop in comparable sales. Signet issued a current-quarter earnings forecast that was largely below estimates, however.

Michaels Companies (MIK) – The arts and crafts retailer missed estimates by 9 cents a share, with quarterly profit of 40 cents per share. Revenue also came in below forecasts.

The workplace messaging platform company’s revenue also beat Street forecasts and Slack raised its full-year outlook as it adds more large corporate users.

Fiat Chrysler (FCAU) – Fiat Chrysler is in a dispute with Italy’s tax authority, which said the automaker had underestimated the value of its U.S. business following its acquisition of Chrysler. The company said it strongly disagrees with the assessment, which could result in a $1.5 billion bill for back taxes.
