Take a look at some of Wednesday’s morning movers:

Apple - Apple reported fiscal second-quarter profit of $12.30 per share , smashing estimates of $10.04. Revenue also scored a solid beat at $39.2 billion versus estimates of $36.8 billion. The results were driven, not surprisingly, by strong demand for iPhones and iPads.

Wal-Mart Stores - The retailer's shares have been downgraded to "hold" from "buy" at Argus Research, which notes the uncertainty surrounding the company's Mexico bribery investigation.

Caterpillar - The construction equipment maker earned $2.37 per share for the first quarter, versus estimates of $2.13, but revenue was short of estimates at $15.98 billion. Caterpillar did raise its yearly earnings per share outlook to $9.50 versus its prior guidance of $9.25.

Boeing - The jet maker earned $1.22 per share for the first quarter, well above estimates of $0.94. Its results were helped by an increase in commercial airplane deliveries.

Harley-Davidson - The motorcycle maker reported first-quarter profit of $0.74 per share, two cents above estimates, with sales well above Wall Street estimates. It also says it will ship more motorcycles this year than it had forecast in January.
