Want to know if your stock is overpriced, maybe ready to take a breather? Then check its PEG. That's Price to Earnings to Growth, or the P/E ratio divided by the growth rate of a company's earnings. It's a quick and easy way to see if your stock may be ahead of its earnings power. It's also one measure a lot of momentum investors rely on as a screening tool.

If a stock's P/E ratio is well above its growth rate, they believe the stock is overpriced and won't touch it. But if the p/e ratio is well below the stock's growth rate, it could signal a bargain. It helps to know your stock's PEG.

Last week's Fed Beige Book report and GDP numbers suggested that the economy may be stabilizing, and this coming week will bring plenty of economic data to confirm or deny that suggestion. On the schedule are consumer credit, construction spending, factory orders, and pending home sales for June, the employment situation, the Import Price Index, and new motor vehicle sales for July, as well as the ISM Manufacturing and Non-manufacturing Indexes for July.

The week will also bring quarterly reports from home builders Beazer Homes USA Inc. (NYSE: BZH), D.R. Horton Inc. (NYSE: DHI), and Pulte Homes Inc. (NYSE: PHM). Yet again, analysts surveyed by Thomson Reuters expect all three to have narrowed their losses in the most recent quarter. However, they've all tended to post deeper-than-expected losses in recent quarters as well. Analysts also expect to see their revenue down 45% or more for the past quarter. They forecast long-term EPS growth of 7% or more, but none of these homebuilders has a First Call consensus buy recommendation, not surprisingly. Short interest is falling off for Beazer and D.R. Horton, and D.R. Horton and Pulte have been reporting positive cash flow from operations, but all three of them said they had more long-term debt than cash in hand last time around. Mortgage insurer PMI Group Inc. (NYSE: PMI) is likewise expected to report that it narrowed its second-quarter loss.

On Wednesday, federal investigators filed mortgage and accounting fraud charges against Beazer Homes USA (NYSE: BZH). The homebuilder will be able to escape prosecution because it agreed to pay $50 million to victims and to accept responsibility for its improper actions.

Beazer found itself charged thanks to its participation in a scheme designed to fraudulently increase its profits and sell homes. Reportedly, the company also participated in an accounting scheme that was designed to "smooth earnings." Thanks to these schemes, homebuyers defaulted on their loans and some neighborhoods saw home values plummet thanks to loan defaults. State and federal investigators have scrutinized Beazer since March 2007, finding that the company's "aggressive sales tactics" contributed to an "unusually high foreclosure rate in many of its local starter-home communities."

The stock market, as measured by the Dow Jones Industrial Average, sharply rebounded from its low of 6440 in March of this year. Currently, as this is written, the notable index is hovering around 8400. That's an increase of 30%. Not bad for two months of trading. While the average is made up of only 30 stocks, those 30 stocks are some of the best. There are also some real losers, such as General Motors (NYSE: GM) and Citigroup (NYSE: C). But for the most part, the index contains the strongest industries with some of the strongest stocks. With that kind of recovery already in place, is it too late to buy stocks or is this just the start of a major rally?

It's about that time again: Pepsi vs. Coke. No, not another taste test or another Battle of the Brands. It's time for the next quarterly results from these two soft drink titans.

Analysts surveyed by Thomson Reuters anticipate that PepsiCo Inc. (NYSE: PEP), global beverage and snack food giant, will report fourth-quarter earnings this week that are 9.1% higher that a year ago, or $0.88 per share. Revenue is expected to total $12.8 billion, which is 3.9% higher than last year. For the full year, the profit is expected to be $3.67 per share on revenue of $43.4 billion, up from $3.38 per share on $39.5 billion in 2007. PepsiCo's earnings met or beat estimates in four of the past five quarters, but missed by only two cents per share in the third quarter. The consensus recommendation of analysts remains to buy PEP. The share price fell to a 52-week low in January and is now 24.4% lower than it was a year ago. During the fourth quarter, PepsiCo declared a $0.42 per share quarterly dividend, agreed to acquire a Spitz International, and announced investments in China and Mexico.

One of the programs which may come with the new economic stimulus package is a big tax credit for people who buy new homes. It would help potential buyers across almost every income class, which is not what was being contemplated a few days ago. According to Bloomberg, "By replacing a $7,500 tax credit for first-time homebuyers earning less than $150,000 with a $15,000 break for all income groups as part of the economic stimulus package, senators effectively are encouraging purchases by higher-income households with a reduced risk of default."

Last week, Moody's said it was reviewing debt ratings on four home builders, including Beazer (NYSE: BZH) and Hovnanian (NYSE: HOV), for downgrades. That did not do the shareholder in the companies any favors.

Homeowners lost $3.3 trillion in the value of their houses last year. A report from Zillow.com, picked up by Bloomberg, said that national home prices dropped 11.6% compared to 2007.

That makes stocks like Hovnanian (NYSE: HOV) and Beazer (NYSE: BZH) sells, even at current depressed levels. HOV shares are down to $1.64 from a 52-week high of $13.50. Beazer is off from a high of $12.40 to $0.98. The company could even face delisting over the next year if it cannot get its share price up.

There is a temptation to think that home-building stocks are so inexpensive that, if the companies can drop inventory prices enough, they can start to improve sales, even if the margins on each home sold are poor. But it is not that simple.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

Last week, Bank of Montreal (NYSE: BMO), one of Canada's oldest and largest banks, reported growth in its fiscal fourth-quarter earnings. But it may be the only one that does, as at least two of the Canadian banks scheduled to report fourth-quarter numbers this week have already released preliminary results that warn of lower earnings due to debt write-downs and trading losses.

Analysts surveyed by Thomson Reuters expect Toronto-based Canadian Imperial Bank of Commerce (NYSE: CM) to post earnings 42.6% lower than a year ago, or $1.28 per share. CIBC beat estimates by a penny in the third quarter, but missed by a penny in the period before that. The bank faces a class-action lawsuit related to investments in collateralized debt obligations consisting of U.S. subprime mortgages. Shares have climbed 20.7% from a recent 52-week low of $39.52, but are down 37.8% in the past three months.

Toronto Dominion Bank (NYSE: TD), Bank of Nova Scotia (NYSE: BNS), and Royal Bank of Canada (NYSE: RY) are expected to report more modest earnings declines of $1.01 per share, $0.73 per share, and $0.83 per share, respectively. All three Toronto-based banks topped estimates in the third quarter. Toronto Dominion and RBC have recently announced plans to offer shares in order to raise capital. Toronto Dominion and Scotiabank have been trading near 52-week lows, and their share prices are down around 39% in the past three months. But only Toronto Dominion has a consensus buy recommendation from analysts.

With a turn of the calendar page, we drift into the middle portion of the current quarter, but the earnings season rolls on. Among the many companies scheduled to report quarterly results this coming week are Time Warner Inc. (NYSE: TWX), Cisco Systems Inc. (NASDAQ: CSCO), News Corp. (NYSE: NWS), and Whole Foods Market International (NASDAQ: WFMI).
