First Solar, Ralph Lauren, Disney and Zillow are big market movers

NEW YORK — Stocks that moved substantially or traded heavily Wednesday on the New York Stock Exchange and the Nasdaq Stock Market:

NYSE

Ralph Lauren Corp., down $16.38 to $173.13

The luxury retailer's shares suffered their largest decline in more than a year after its outlook implies a weak quarter ahead. Comparable store sales also disappointed some investors.

J.C. Penney Co. Inc., down 48 cents to $12.80

A terrible week for the retailer is intensified by a larger sell-off in the sector. Analysts are now honing in on the amount of money the retailer is burning through and how long that can last.

AOL Inc., up 51 cents to $36.69

The Walt Disney Co., down $1.14 to $65.91

The entertainment company says the cool reception for "The Lone Ranger" could lead to a loss in its fiscal fourth quarter.

Computer Sciences Corp., up $4.24 to $54.20

Profits at the technology company more than tripled in the most recent quarter and its shares hit a two-year high.

Nasdaq

The online real estate company's shares had a tailwind earlier this week from the announcement that President Barack Obama would answer questions about housing on its website. But that vanished after it posted a second-quarter loss, reporting that costs had doubled.

First Solar Inc., down $6.28 to $40.47

There is some skepticism over a tie-up between General Electric, which will buy a stake in the solar company in exchange for ownership of GE's competing thin-film solar panel technology. The Tempe, Ariz., company also posted earnings and revenue that fell short of Wall Street expectations.

Finisar Corp., up $2.95 to $22.08
