Analyst upgrades:

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

• AK Steel Holding Corp. (NYSE: AKS) reported better-than-expected Q3 results but shares fell anyway.
• Baidu Inc. (NASDAQ: BIDU) posted strong Q3 results but shares sold off on a disappointing guidance.
• Burger King Holdings Inc. (NYSE: BKC) said lower Q1 earnings fell short of analysts expectations.
• Dreamworks Animation SKG Inc. (NYSE: DWA) topped Q3 profit and revenue estimates, lifting shares.
• Geron Corp. (NASDAQ: GERN) posted a narrower-than-expected Q3 loss, sending shares sharply higher.
• Honda Motor Co. Ltd. (NYSE: HMC) reported lower Q2 earnings and sales on weak demand for cars.

Even the cheap stuff gets cut when jobs are scarce. Burger King (NYSE: BKC), the second largest burger chain, saw fiscal first quarter profit fall 6% year-over-year, as diners opted to make their own meals at home.

Another part of the problem, though, is that competitors have cut their prices aggressively in order to bring customers through the door, a move that can have an upside for market share but doesn't always restore revenue lost to a recession.

Burger King Holdings Inc. (NYSE: BKC) announced plans Wednesday to overhaul its 12,000 locations worldwide. The fast-food giant is seeking a sleeker, futuristic look that includes LCD-screen menus, rotating chandeliers, and corrugated metal and brick accents (see pictures at the above link) on the inside, as well as metal canopies and additional signs on the exterior.

The new upscale design, called 20/20, is expected to cost franchisees between $300,000 to $600,000 per restaurant. Some 60 locations have already been remodeled, including in Miami, Mexico City, Edinburgh, and Shanghai, and 75 more are expected to be completed by the end of 2010. All new restaurants will be built using the 20/20 design.

Yum! Brands (NYSE: YUM), which competes with McDonald's (NYSE: MCD), Burger King (NYSE: BKC), and Wendy's/Arby's Group (NYSE: WEN) for the right to feed consumers on the go around the world, issued a Q3 report after the bell on Tuesday that was decent in many respects. Earnings per share on an adjusted basis increased over 20% to 70 cents. This performance absolutely embarrassed the analysts, who were looking for a mere 58 cents per share according to our earnings preview.

So, that was one of the decent parts. Actually, I'd say it was a little more than decent. But, unfortunately, the top line didn't grow. Total revenues actually declined 2%.

At the time of this writing, shares of Yum! Brands (NYSE: YUM), a company that competes with McDonald's (NYSE: MCD), Burger King (NYSE: BKC), and Wendy's/Arby's Group (NYSE: WEN), were trading higher by well over 4%. Volume was doing well, too. Interestingly enough, Yum! Brands will be reporting Q3 earnings on Tuesday, October 6, after the bell. Does this mean that you should buy in ahead of the release?

On the surface, I suppose the market is telling you that Yum! Brands would indeed make a good earnings trade. Not only is the stock up nicely this afternoon, but it isn't too far from a 52-week high.

There are no sure-fire gains in trading or investing, even if the company's/sector's data is pointing to a move higher or lower. The short of Aeropostale (NYSE: ARO), recommended on May 15, 2009 at a price of $31, has been stopped out at $42, and the short of Burger King (NYSE: BKC), recommended on the same day at a price of $17.35, has failed to make the new lows envisioned.

Aeropostale posted record Q2 results, and recently announced a 9% increase in August same-store sales, despite a cluttered sector (young-teenager casual apparel, accessories), and the "frugal consumer" era.

If you're trying to get your head around some stock strategies for the upcoming fall trading season, you might want to consider dividend yields. Volatility could increase since we've had such a run-up in many equities, so thinking about payouts is probably advisable.

I was looking around for some higher-yielding blue chips and became interested in McDonald's (NYSE: MCD). As of last Friday's closing price, McDonald's yields almost 3.6% on an annual basis. It pays out 50 cents per share per quarter according to its corporate website.

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.

Burger King Holdings (NYSE: BKC) is on the upswing today after the fast-food chain topped analysts' earnings expectations. In its fiscal fourth quarter, the burger baron banked a profit of $58.9 million, or 43 cents per share, representing a 16% increase from the year-ago period. Revenue dipped 2% to $629.9 million, while same-store sales fell by 2.4%. By contrast, analysts were looking for a profit of just 33 cents per share on $632 million in revenue.

Looking ahead, the restaurant chain warned that it expects sales to be soft through Christmas. As a result, Burger King declined to issue specific earnings guidance for the current fiscal year. Additionally, the company plans to slow the pace of its new store openings; rather than the 360 new outlets opened in fiscal 2009, Burger King is targeting 250 to 300 openings in fiscal 2010.

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.

Yum! Brands (NYSE: YUM), a chain of restaurant trademarks that competes with McDonald's (NYSE: MCD), Burger King (NYSE: BKC), and Wendy's/Arby's Group (NYSE: WEN), delivered up a nice hot serving of earnings on Tuesday after the bell.

For the second quarter, net sales dropped 7%. Earnings on an adjusted basis increased 10% to 50 cents per share. This was actually much better than analysts' expectations. Wall Street was only counting on 43 cents per share, according to Bloomberg. However, the market is always looking forward, so there was a bit of bad news in terms of guidance pertaining to same-store sales.

Ruby Tuesday (NYSE: RT) reported Q4 results on Tuesday (hey, what day did you expect the company to do it on?) after the bell. By the looks of the price action going into the report, as well as the price action after the report, you would have thought that the results were incredible. They were, in terms of an earnings beat, but other aspects of the report gave me pause.

Ruby Tuesday made 28 cents per diluted share during the fourth quarter. According to Reuters, analysts were only looking for 20 cents of per-share profit. Okay, so we know why Wall Street was so excited. Beating by 8 cents is impressive.

Sonic (NASDAQ: SONC), a fast-food chain whose colleagues include Burger King (NYSE: BKC), McDonald's (NYSE: MCD), Wendy's/Arby's Group (NYSE: WEN), and Yum! Brands (NYSE: YUM), reported earnings for the third quarter on Tuesday after the bell. The shares have done well today on the news. As I write this, Sonic's stock is up well over 12% in afternoon trading. Volume is great. Do you want to get in on the action?

Sonic said it earned an adjusted 24 cents per share. This article reported expectations as being $0.20 per share, so management beat the bottom line by a nice amount. We'll throw that result on the positive side of the line.

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

• Baidu Inc. (NASDAQ: BIDU) reported better-than-expected Q1 earnings as revenues surged in the quarter.
• Burger King Holdings Inc. (NYSE: BKC) just beat Q3 expectations despite weak same-store sales growth.
• Corn Products International Inc. (NYSE: CPO) Q1 results were dragged down by higher corn costs.
• Dow Chemical Co. (NYSE: DOW) Q1 earnings sank on falling sales, job cuts and acquisition costs.
• Eastman Kodak Co. (NYSE: EK) reported a deeper-than-expected Q1 loss and suspended its dividend.
• Energizer Holdings Inc. (NYSE: ENR) posted better-than-expected Q2 earnings but revenue declined.
