POPS (stocks that jumped higher)

McDonald’s (MCD) popped 4%. Deutsche Bank upgraded the fast food giant to ‘buy’ from ‘hold’ citing valuation. - I'd wait for a pullback toward $51, counsels Pete Najarian.

Arch Coal (ACI) popped 4%. Coal and commodities in general ripped higher with the Reuters/Jefferies CRB index touching a 6-month high. - Coal names, love 'em, says Joe Terranova.

Analog Devices (ADI) popped 16%. The chip name reported stronger than expected second-quarter earnings and offered an optimistic third quarter forecast. - I like the stock but I don't know if I'd buy it here, says Joe Terranova.

DROPS (stocks that slid lower)

BJ’s Wholesale (BJ) dropped 4%. The third largest warehouse operator closed lower despite beating on earnings and raising its full year outlook. - I'd take profits and get out, says Jeff Macke.

Wells Fargo (WFC) dropped 4%. This bank was among the many losers as the broad financial services sector sold-off.

Palm (PALM) dropped 9%. An analyst downgraded the stock to ‘underperform’, saying expectations for the Pre have become overdone. - I think the stock is ahead of itself but under $10 it's interesting, says Pete Najarian.
