Lowe's Cos. (NYSE: LOW) shares are little changed after the second-largest home improvement retailer reported better-than-expected second quarter earnings. They still should be avoided.

Earnings fell 7.9% to $938 million, or 64 cents a share. Sales rose 2.4% to $14.5 billion, up from $14.2 billion in the second quarter of 2007. The results surpassed the 56-profit and $14.12 billion in revenue expected by Wall Street. Nonetheless, the company continues to face a tough slowdown and gave disappointing third quarter guidance.

"We are encouraged by our results and our continued market share gains, but the macro economic factors pressuring consumers and the ongoing challenges and uncertainty of the financial markets suggest a cautious sales forecast for the balance of fiscal 2008 is prudent," said Chief Executive Robert A. NIblock in the earnings release.

Lowe's opened 23 new stores in the last quarter and expects to open 38 new stores during the current one. Is now really the right time to be adding so many new stores? There is a housing crisis, right? Square footage is expected to grow by 10%. The company is spending $34 million opening new locations.

Moreover, comparable same-store sales are expected to drop 5% to 7%, which Bloomberg says is less than what some analysts forecast. Earnings per share will be 27 to 31 cents in the quarter versus 43 cents a year earlier. Analysts had expected 33 cents. Profit for the year is seen at $1.48 to $1.56. Wall Street consensus is for $1.50.

For now, investors would be wise to avoid Lowe's and Home Depot Inc. (NYSE: HD), which reports tomorrow, until the housing market rebounds. That won't be until next year at the earliest.
