Canadian banks are scheduled to step into the earnings spotlight this week, with third-quarter reports coming from Bank of Montreal (NYSE: BMO), Bank of Nova Scotia (NYSE: BNS), Canadian Imperial Bank of Commerce (NYSE: CM), Royal Bank of Canada (NYSE: RY), and Toronto-Dominion Bank (NYSE: TD). While Canadian banks on the whole held up better than their U.S. counterparts during the financial crisis, these five are expected to report that their earnings are still declining in the most recent quarter.

Analysts surveyed by Thomson Reuters are looking for EPS for these banks to have fallen from 15% to 25% from a year ago. Their long-term EPS growth forecast is for between 10% and 12%, which is in the same range as U.S. rivals JPMorgan Chase & Co. (NYSE: JPM) and Wells Fargo & Co. (NYSE: WFC), but better than Bank of America Corp. (NYSE: BAC) and Citigroup Inc. (NYSE: C). Earnings multiples for these Canadian banks are 10x to 12x, but none of them have a First Call consensus recommendation is to buy. The Motley Fool, though, considers TD as a value stock and RY a stock poised to pop. All of them are trading much closer to their 52-week highs than lows, and shares of all are up more than 100% since March lows.

Most investors got slammed last year, down 50% or more in their investments. Didn't matter if they owned stocks or real estate, they got hammered. Many have to start over. And if they're near retirement, it's scary. Years of patient investing wiped out, gains that were made over a long time disappeared frighteningly fast.

But now it's time to begin fresh, to rebuild. What's the safest way to regain some or all of the losses without suffering another wipeout?

Lennar (NYSE: LEN), whose colleagues include Toll Brothers (NYSE: TOL) and D.R. Horton (NYSE: DHI), reported earnings for the second quarter on Thursday. Since it is a homebuilder, you can expect that it would be a tough one to look at in many respects. There was a revenue decline of over 20%. And there was no profit. Lennar said it lost 76 cents per diluted share.

According to Michael Fowlkes and his earnings preview, Lennar did not satisfy Wall Street's outlook. Analysts were expecting a loss somewhere closer to 63 cents per share. That didn't stop the stock from going up, though. Lennar closed higher yesterday by over 17%. Volume was likewise incredible. Apparently, the market was focusing on the revenue beat.

This week brings a small flurry of end-of-the-calendar-quarter earnings reports. And for the most part, the expectations of the analysts surveyed by Thomson Reuters aren't very high. Companies expected to report declining earnings in the most recently concluded quarter include America's Car-Mart Inc. (NASDAQ: CRMT), Bed Bath & Beyond Inc. (NASDAQ: BBBY), ConAgra Foods Inc. (NYSE: CAG), Jabil Circuit Inc. (NYSE: JBL), Jackson Hewitt Tax Service Inc. (NYSE: JTX), Monsanto Co. (NYSE: MON), and Sonic Corp. (NASDAQ: SONC).

Hovnanian Enterprises (NYSE: HOV), a home builder whose related companies include Toll Brothers (NYSE: TOL), Lennar Corp. (NYSE: LEN), and D.R. Horton (NYSE: DHI), reported Q2 results on Tuesday after the bell. The company reported a loss of $1.50 per share (the results included a gain related to debt extinguishment). That unfortunately did not meet analyst expectations according to Trey Thoelcke's earnings preview. Analysts were looking for a loss of $1.26 per share.

However, things do look better. Last year at this time, the loss recorded by Hovnanian was a whopping $5.29 per share. Revenues, however, plummeted to $398 million from over $770 million. Analysts were expecting only $348 million according to the preview.

Still wondering whether the housing market has bottomed? Well, the next couple of days should offer some clues, as pending home sales numbers for April are due out later this morning, and home builders Hovnanian Enterprises Inc. (NYSE: HOV) and Toll Brothers Inc. (NYSE: TOL) will be releasing their quarterly results. While both are expected to have narrowed their losses, their revenues are expected to have shrunk by half, as well.

Much of the attention this week will no doubt be on how the impending General Motors (NYSE: GM) bankruptcy will shake out, as well as the usual economic concerns: Has the housing market bottomed? Will oil prices keep rising? Is the employment situation getting any better? And so on (see highlights of the economic calendar below).

What probably won't get much attention are quarterly earnings, as the earnings season for this quarter winds down. But there are a few reports that analysts surveyed by Thomson Reuters have high hopes for.

Toll Brothers Inc. (NYSE: TOL), a builder of luxury homes, issued some preliminary revenue results for its second quarter and six-month period. Now, there isn't a lot of surprising stuff here. Things are down, to be certain. What you possibly might be surprised by is the way the stock is trading. As I write this, shares of Toll Brothers have shed about 1% of their value. While that might sound logical because of the presented data, I do have to say that, to me at least, the fact that the shares haven't plunged on the news is almost an encouraging sign.

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?

Without envy there would be no capitalism. We would have no reason to work as hard as we do. One thing we all like to strive for is a bigger and better house (well, maybe not so much today).

At the top of the homebuilder food chain is Toll Brothers (NYSE: TOL). This company has held up relatively well considering the disaster in the housing market.

With the bottom finally in sight, look for more to be envious of a Toll Brothers home. They are quite nice. I rate TOL a buy.

Next: Deadly sin stock #4

See all 7 deadly sin stocks.

Just for fun, I thought I'd find a stock that loosely symbolizes each of the 7 Deadly Sins -- greed, wrath, envy, pride, lust, sloth and gluttony -- to see how it fares against my momentum criteria.

Now, I'm not saying any of these companies are bad or evil. And I don't know whether our new climate of parsimony means the "greed is good" era of the 1980s is dead. What I do know is which stocks are in a position to profit today and which aren't.

Here's a fun look at some stocks that symbolize the 7 Deadly Sins and how I expect them to perform.

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

• Adobe Systems Inc. (NASDAQ: ADBE) was upgraded following its Q1 release and guidance.
• America's Car-Mart Inc. (NASDAQ: CRMT) posted higher earnings in Q3 and same-store sales growth.
• AT&T Inc. (NYSE: T) was upgraded by an analysts who felt that consensus estimates are beatable.
• Berkshire Hathaway Inc. (NYSE BRK.A) suffered a big profit decline, its fifth straight quarterly decline.
• Blackstone Group (NYSE: BX) posted horrible Q4 results as the values of its portfolio shrank.

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.
