Pops & Drops: Lennar, Sprint...

Following are the moves you might have missed. Find out why shares of Lennar and Deere popped while Sprint and Supervalu dropped.

POPS (stocks that jumped higher)

Lennar (LEN) popped 6% on the week. The company reported quarterly results that beat Wall Street estimates and said it expected a profitable 2011. - I'm not on board, says Karen Finerman.

Deere (DE) popped 6% on the week. Although JPMorgan upgraded the stock to ‘Overweight’ from ‘Neutral’ the weekly gains are more likely a bet that farmers will buy more equipment in the wake of surging crop prices. - I think the stock trades up to $101, says Guy Adami.

ARM Holdings (ARMH) popped 39%. Catalysts included an RBC upgrade to ‘Outperform’ and a Barron’s article about the upgrade; both pegged to the Microsoft decision to build its next version of Windows not just on Intel and AMD processors, but also chips using the technology of ARM Holdings. - At this level I can't be a buyer, says Brian Kelly.

DROPS (stocks that slid lower)

Sprint (S) dropped 5% for the week. Investors fear that rivals Verizon and AT&T may squeeze this company, since both now offer the extremely popular iPhone on their networks. - Tough week for Sprint, says Tim Seymour.

Supervalu (SVU) dropped 14%. The grocery store chain posted a loss for its third-quarter and lowered its guidance citing weak sales and tighter margins. - It looks more like a value trap to me, says Patty Edwards.
