Earnings reports continue to dribble in as the quarter winds down. Much of the attention this week will be on homebuilders KB Home (NYSE: KBH) and Lennar Corp. (NYSE: LEN) as investors look for any sign that the housing sector has bottomed (home sales numbers are also due out this week; see below). Analysts surveyed by Thomson Financial anticipate that both companies will report that they narrowed their losses in the most recent quarter.

KB Home's expected $1.25 per share loss, on revenue of $725.5 million, compares to the previous quarter loss of $3.30 and to a year-ago loss of $6.19. However, KB Home's losses in the past few quarters have been deeper than expected. The Los Angeles-based homebuilder's long-range earnings growth forecast is 10.5%, less than the S&P 500. Analysts continue to recommend holding KB Home, and have for at least 120 days. Shares, however, reached a new 52-week high of $31.69 on Friday, and they are up 10.5% year to date.

Lennar is expected to post a loss of 52 cents per share, on revenue of $1.1 billion. That compares to the previous quarter's per-share loss of 76 cents and to a year-ago loss of $3.25. While Lennar also has tended in the past few quarters to miss expectations, the Miami-based company managed a positive surprise in the first quarter of 2008. Lennar's long-range earnings growth forecast is 10.3%, about the same as KB Home's. Analysts also recommend holding Lennar. Friday, shares of Lennar also reached a 52-week high, $27.75, but they are down 6.4% year to date.

This post is part of a series on some of the most memorable companies that have disappeared.

What goes up, must come down. It was a cute ad. Who knew it would turn out to be so prophetic?

Pets.com will go down in history as a textbook example of dot-com flame-out, going from IPO to liquidation in nine short months.

Founded in 1998, the company, which had the bright idea of selling pet food and supplies to the public via the internet, went public in February 2000 and raised $82.5 million.
