Dollar Tree (NASDAQ: DLTR) has more than 3,500 stores that sell its inventory of toys, durable housewares, candy, seasonal goods, and so on for a $1. Its other stores, operating as Deal$, sell most of its inventory at $5 or less.

This deep-discount retailer is generally considered to be the leader of its class and is rated a "buy" (four stars) by S&P with a target of $59.

The stock executed a major long-term bullish breakout at around $45. Technically this breakout is major and targets the stock at over $65.

When selecting which stocks to buy, ratings from agencies like Standard & Poor's can be useful in creating a balanced portfolio.

But did you know technical analysis is the most accurate way to predict where a stock -- or the market for that matter -- is going?

Technical analysis is more of an art than a science, but when used correctly it can boost your profits to new heights. I took a look at stocks that S&P has a four- or five-star rating on and analyzed their charts to come up with six great technical trades for you.

Family Dollar Stores (NYSE: FDO), like Dollar Tree (NASDAQ: DLTR), is benefiting from the soft economy. Consumers love paying low prices, so they flock to these retail business models like moths to a flame. And judging by Family Dollar's Q4 report, people are still having a great time saving money.

Net income increased over 13% to 43 cents per share, which was two pennies higher than Wall Street's forecasts, according to our earnings preview. Unfortunately, sales weren't so great. Total sales went up 2.6%, and same-store sales saw a mere 1% gain. I would have expected higher growth in the comps metric.

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

• American Eagle Outfitters Inc. (NYSE: AEO) Q2 profit fell short of estimates as same-store sales declined.
• Ann Taylor Stores Corp. (NYSE: ANN) Q2 earnings beat very low expectations and same-store sales fell.
• Big Lots Inc. (NYSE: BIG) reported better-than-expected numbers for Q2, sending shares upward.
• Burger King Holdings Inc. (NYSE: BKC) posted a better-than-expected Q4 profit though revenue declined.
• China Petroleum & Chemical Corp. posted a record Q2 profit after restrictions on fuel prices were lifted.
• Dell Inc. (NASDAQ: DELL) said its Q2 earnings declined, but they still topped analysts' expectations.

Dollar Tree (NASDAQ: DLTR) reported a truly excellent quarter. The stats contained in the release are monumentally impressive. Dollar Tree increased sales almost 12% in Q2, a performance that essentially matched expectations. Per-share income soared 50% to 63 cents, beating estimates of 54 cents per share.

This is one of those situations where all the numbers point toward future growth. Margins increased, as did cash from operations (I enjoyed the fact that capital expenditures didn't go up too much). Same-store sales moved higher by 6.8%, and management's outlook for the rest of the fiscal year received a boost. And judging by the guidance, I'd say that Dollar Tree shares aren't overly expensive at the moment. Let's add a technical factor to go along with my opinion of the valuation: Dollar Tree closed Wednesday to the upside by well over 4% on the earnings news, not far at all from a 52-week high. The price action was accompanied by healthy volume.

Dollar Tree Stores Inc. (NASDAQ: DLTR), the nation's leading operator of dollar stores, is scheduled to discuss its second-quarter 2009 results tomorrow morning in a conference call at 9:00 AM ET. You can catch the live webcast of the call on the company's website.

In the three months that ended in July 31, Dollar Tree saw the retirement of a long-time board member. Analysts surveyed by Thomson Reuters expect the company to report that its earnings grew 22.2% from a year ago to $0.54 per share. Revenue for the quarter is expected to be 11.2% higher to $1.2 billion, in line with preliminary results. Analysts so far expect the third-quarter results to be about the same. The Chesapeake, Va.-based company has topped earnings expectations in recent quarters, by as much as six cents per share.

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.

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.

The second half of the calendar year has begun, and earnings return to the spotlight this week. As usual, Alcoa Inc. (NYSE: AA) is among the first of the S&P 500 to report quarterly results. For the second quarter in which Alcoa agreed to sell its wire harness and electrical distribution business and its fastening systems business expanded into Morocco, analysts surveyed by Thomson Reuters expect the New York-based aluminum producer to report swinging to a net loss of $0.34 per share from a profit of $0.66 per share in the year-ago period. Second quarter revenue is expected to have fallen 48.3% to $3.9 billion. The full-year forecast is currently for a loss of $1.04 per share and revenue of $16.7 billion (-38.0%). Alcoa has missed expectations in the past three quarters, by as much as 17 cents per share. The long-term EPS growth forecast is 10.0%, which is better than the sector average. Alcoa slashed its dividend earlier this year, and the First Call consensus recommendation remains to hold AA. However, TheStreet.com recommends it as an against-the-grain pick. At $9.86, shares are down 12.4% since the beginning of the year, and recently have been bumping up against the 200-day moving average.

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

• American Eagle Outfitters Inc. (NYSE: AEO) reported better-than-expected Q1 earnings, lifting shares.
• AutoZone Inc. (NYSE: AZO) posted a better-than-expected Q3 profit said it will continue to buy back shares.
• Bank of Montreal (NYSE: BMO) reported lower Q2 earnings and also announced 1,100 layoffs.
• Big Lots Inc. (NYSE: BIG) higher Q1 earnings topped estimates even though same-store sales fell.
• BioMed Realty Trust Inc. (NYSE: BMR) earnings prospects after the recent capital raise led to a downgrade.

Dollar Tree (NASDAQ: DLTR) saw a nice increase in its bottom-line profit. The retailer, which reported earnings for the first quarter earlier this week, said it made 66 cents per share, good for an increase of more than 37%. Revenues increased 14%, and same-store sales went up a whopping 9%. So many retailers would absolutely kill to have that same-store number.

It's no secret why Dollar Tree is thriving. Bad economy plus items-that-sell-for-a-dollar-each equals retail success. Brand equity is important. So is convenience. But a cheap price point oftentimes trumps all.

After the Memorial Day holiday in the United States, the earnings spotlight turns to Canadian banks: Bank of Montreal (NYSE: BMO), Canadian Imperial Bank of Commerce (NYSE: CM), Royal Bank of Canada (NYSE: RY), and Toronto-Dominion Bank (NYSE: TD) are all scheduled to report their second-quarter results.

While banks north of the border of generally have held up better than their U.S. counterparts, analysts surveyed by Thomson Reuters expect the four listed above to report that earnings declined between 20% and 30% since the same period of last year. All four have P/E ratios around 10, and they are paying dividends. Shares of all four have surged 50% to 83% in the past three months, but are still 26% to 38% lower than a year ago.

The New York Times reports that dollar stores are thriving as consumers look to pinch pennies: "The nation's dollar stores, those once-dowdy chains that lured shoppers by selling some or all of their merchandise for $1, are suddenly hot. They are busily opening new stores, outfitting existing stores with refrigerators and freezers, and sprucing up their aisles with better lighting, fresh paint and new signs."

Shares of Dollar Tree Inc. (NASDAQ: DLTR) have been strong performers as the company's same-store sales numbers have been terrific and the company plans ambitious new store opening plans. KKR's $7.3 billion acquisition of Dollar General in March of 2007 looks like one of the few good buyout deals to have come at the peak of that boom.

Analysts surveyed by Thomson Reuters expected the parade of earnings declines to continue into the final week of February, with Martha Stewart Living Omnimedia Inc. (NYSE: MSO), Nordstrom Inc. (NYSE: JWN), Home Depot Inc. (NYSE: HD), Wynn Resorts Ltd. (NASDAQ: WYNN), Macy's Inc. (NYSE: M), DreamWorks Animation SKG Inc. (NYSE: DWA), Limited Brands Inc. (NYSE: LTD), Target Corp. (NYSE: TGT), Royal Bank Of Canada (NYSE: RY), Del Monte Foods Co. (NASDAQ: DLM), Kohl's Corp. (NYSE: KSS), Washington Post Co. (NYSE: WPO), Dell Inc. (NASDAQ: DELL), Gap Inc. (NYSE: GPS), Campbell Soup Co. (NYSE: CPB), RadioShack Corp. (NYSE: RSH), and H.J. Heinz Co. (NYSE: HNZ) all expected to post lower earnings for the most recent quarter. Office Depot Inc. (NYSE: ODP), Saks Inc. (NYSE: SKS), and Cooper Tire & Rubber Co. (NYSE: CTB) are expect to have swung to a loss.

It comes as no surprise that the top performer among the stocks comprising the S&P 500 Index is a retailer focused on delivering quality products and services at a discount price.

Family Dollar Stores (NYSE: FDO) increased nearly 30% in 2008, compared with a decrease of 40% in the S&P 500.

Defying the expectations of gloomy analysts who are paralyzed by their inability to value companies during the last 12 months, and by short sellers who perceived a price drop following the high level performance in 2008, the stock is continuing its climb as we enter the 2009 trading year.

Family Dollar reported first quarter earnings Wednesday, which exceeded analysts' expectations and company projections.

Earnings for the period were up by 14%, with revenue increasing by 4.2% and same-store sales up a healthy 2.1%. Market reaction to the report is stunning, with FDO up more than 14% at the close.

Family Dollar CEO Howard Levine, son of founder and Chairman Emeritus Leon Levine, issued a forecast of continued growth for the next quarter and for all of 2009.

The company is now projecting earnings of $1.63 to $1.81 per share for fiscal year 2009. Earlier forecasts were in the range of $1.58 to $1.78. Projections of same-store sales growth for the year were also increased from a range of 1%-3% to 2%-4%.

FDO combines conservative leadership with a consumer-friendly neighborhood store environment, and a product mix appealing to cost-conscious consumers to deliver value and a positive shopping experience. With minimal exposure to price-volatile electronic and apparel inventory, company performance is not likely to be adversely affected by a prolonged economic downturn.

FDO has more than 6,000 locations in 44 contiguous states. The company has effectively managed its rapid growth during the last five years, having opened more than half of its stores during this period.
