The turmoil in the markets makes it too easy to justify selling any stock these days. Yet, while panic never helps investors, it's still a good idea to play devil's advocate with investments.

Consider home fix-it retailer Lowe's (NYSE:LOW). Though the company is giving many positive indications lately, you'll find that more than a few of the 2,238 Motley Fool CAPS members who weigh in on the company offer reasons to be bearish.

Here at the Fool, we like to consider both the good and the bad sides of an investment, so I'm highlighting three of the main bearish arguments on Lowe's. Be sure to read the bullish side as well, and then weigh in with your own comments below or rate Lowe's in CAPS.                     

1. Weak sales
Despite some positive signs in Lowe's and competitor Home Depot's (NYSE:HD) recent quarterly reports, no one's popping champagne because both reported falling earnings and same-store sales, and Lowe's hasn't experienced a full rebound. Consumers are still reserved about spending for big home improvement projects, and many investors want to see some sales growth before they're ready to celebrate.

2. No robust turnaround yet
MasterCard's (NYSE:MA) SpendingPulse data recently showed a win for retail holiday sales, and stores like Target (NYSE:TGT) and Costco (NASDAQ:COST) reported stronger business. But with rising mortgage delinquencies at Fannie Mae (NYSE:FNM) and Freddie Mac (NYSE:FRE) adding to the mortgage mess and unemployment levels still high, some investors don't see the positive news outweighing the risks ahead.                

3. Losing momentum
Lowe's stock recently reached a new 52-week high, and some CAPS members think shares are priced at a premium and don't have much room to run. And some investors get the feeling that a good portion of Lowe's insiders think the same thing, because there has been increased insider selling in recent months. While the selling doesn't amount to the level of "dumping and running," the run-up in share price, coupled with significant economic challenges, makes it tough for some to hold onto shares.
