Casual restaurant chain Buffalo Wild Wings (NASDAQ: BWLD) has been on fire this year, with the stock up more than 63% year-to-date. The company could see its positive price action accelerate after its upcoming turn in the earnings spotlight; BWLD is slated to unveil its first-quarter results on Tuesday, April 28, after the close of trading.

Analysts, on average, are expecting BWLD to report a profit of 46 cents per share, up from 36 cents per share in the first quarter of 2008. The company has a mixed history in the earnings confessional: in its previous four reports, the chain has exceeded analysts' estimates twice, met them once, and fallen short on one other occasion.

As the quarterly reports continue to roll out and the market continues to rally, optimism seem to be rising. Analysts certainly have high hopes for some companies reporting earnings this week.

Analysts surveyed by Thomson Reuters expect First Solar Inc. (NASDAQ: FSLR) to report first-quarter earnings of $1.51 per share, which is 62.3% higher than a year ago. Revenue for the quarter is expected to be 105.6% higher, or $404.9 million. First Solar earnings have topped expectations in the past five quarters, by as much as 47.3%. The long-term EPS growth forecast is 40.6% and the forward PE ratio estimate is 23.0. In the previous quarter, Tempe, Ariz.-based First Solar reported having more cash on hand than debt. The First Call consensus recommendation is to buy FSLR; CNBC recently included it as a stock pick. First Solar has announced that it will build new solar power plants in Nevada and Germany. Its share price has risen 6.9% since the beginning of the year to $147.46.

Two leading advisors -- both known for an expertise in technical analysts -- are bullish on the prospects for Buffalo Wild Wings (NASDAQ: BWLD), which operates and franchises casual food restaurants in 38 states.

Here's an overview of the stock from Joseph Hargett, an analyst with Schaeffer Investment Research, and Richard Schmidt, editor of The Stellar Stock Alert.

Schmidt explains, "You've got to love the action of Buffalo Wild Wings. Last month, the stock jumped up nearly 25% in one day and continued to move up.

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

• Applied Materials Inc. (NASDAQ: AMAT) posted a Q1 loss and announced a workforce reduction.
• ArcelorMittal (NYSE: MT) swung to it's first ever quarterly loss due to lower demand and a big write-down.
• Buffalo Wild Wings Inc. (NASDAQ: BWLD) shares surged after it posted strong Q4 results.
• Chipotle Mexican Grill Inc. (NYSE: CMG) posted better-than-expected Q4 earnings as revenue surged.
• Genzyme Corp. (NASDAQ: GENZ) topped Q4 earnings estimates, sending shares higher.
• Global Traffic Network Inc. (NASDAQ: GNET) weaker-than-expected Q2 results led to a downgrade.
• Level 3 Communications Inc. (NASDAQ: LVLT) shares fell despite its upside surprise for Q4.
• Lions Gate Entertainment (NYSE: LGF) posted a bigger-than-expected Q3 loss despite revenue growth.

When Buffalo Wild Wings (NASDAQ: BWLD) reported a sharp drop in earnings for the third quarter last November, the stock plummeted to a 52-week low of $14.50 during the succeeding two months.

At the time, I suggested that the fundamentals at the company were so strong that the analysts downplaying the stock and the investors driving the price down were mistaken.

BWLD recovered in early December and held on to those gains for the first part of 2009. With the release of the fourth-quarter earnings report yesterday, the stock has added another 30%-plus to its price.

While customers may not realize how appropriate it is to be picking meat off the bones of chicken wings in hard times (I'll bet many a Depression-era cook made two chicken wings into a whole family's meal), investors are happily cashing in on the meaty prospects of Buffalo Wild Wings (NASDAQ: BWLD) this week. After reporting a shocker of a quarter -- up 28.7% over the year-earlier quarter with $7.7 million, or $0.43 per share, on revenue $121.2 million -- investors were heartened. It was just three months ago that BWLD missed expectations with net income of $4.6 million, or $0.25 per share, on revenues of $106.1 million. Same-store sales at company-owned stores were up 6.8% in the third quarter compared to a 4.5% growth in the fourth quarter.

Chipotle (NYSE: CMG) closed at $51.31. CMG is scheduled to report Q4 on February 11. CMG February call option implied volatility is at 82, puts are at 91; above its 26-week average of 57, according to Track Data, suggesting larger price movement. CMG puts are more expensive than puts because CMG is difficult to borrow.

Buffalo Wild Wings (NASDAQ: BWLD) closed at $22.67. BWLD, an operator and franchisor of 564 restaurants, is scheduled to report Q4 EPS on February 11. BWLD February 22 straddle is priced at $3.95, March 22 straddle is priced at $5.20. BWLD February option implied volatility is at 117, March is at 85; above its 26-week average of 80, according to Track Data, suggesting larger price movement.

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.

This week, the short-term rally of the last few days of the holiday season was over. While many hope the economy would start rebounding toward the end of the year, more voices are now heard saying the recession will be longer and deeper than estimates. The only thing that could help is a proper stimulus plan.

Indeed, President-elect Obama's transition team and his chosen staff have already been working on a plan, trying to push legislators to act swiftly. As investors received news of one dismal economic report after another -- from retail sales, auto sales, housing, manufacturing and employment -- the corporate side also continued to show considerable weakness with earnings warnings coming nearly daily.

The real question is whether the stimulus plan and the Federal Reserve actions, alongside similar moves taken around the world, could give the boost the economy so desperately needs. It seems several BloggingStocks contributors believe this might be the case as they looked at long-term investment ideas. Here are some of their picks from the past week:

Buffalo Wild Wings (NASDAQ: BWLD) actually saw an increase in value of 62.3% during the quarter. It has a strong capital position and is nearly debt free. It has actually seen a third-quarter same-store sales growth of 8.3%. There has been some pressure on the stock following an earnings miss due to growth, creating an opportunity for astute investors, says Jamie Dlugosch.

Analyst upgrades:

• Jefferies upgraded Buffalo Wild Wings (NASDAQ: BWLD) to Buy from Hold on valuation with the stock down 65% in two months as they believe the company has a "best-in-class fundamental story." The firm lowered its target to $25 from $30.
• Morgan Stanley upgraded Sanofi-Aventis (NYSE: SNY) to Overweight from Equal Weight on valuation and believes near-term cost reductions could provide a positive catalyst.
• Citigroup upgraded New York Times (NYSE: NYT) to Hold from Sell and lowered its target to $5.50 from $7 on valuation and believes the dividend cut will boost the company's liquidity.
• Pantry (NASDAQL PTRY) was upgraded to Outperform from Market Perform at Friedman Billings.
• LECG Corp (NASDAQ: XPRT) was raised to Buy from Neutral at UBS.
• Thomson Reuters (NYSE: TRI) was upgraded at RBC Capital to Outperform from Sector Perform.

• Credit Suisse cut Ericsson (NASDAQ: ERIC) to Underperform from Outperform due to expectations for a decline in wireless infrastructure spending.
• ING downgraded shares of Rio Tinto (NYSE: RTP) to Hold from Buy as they believe it will be challenging for the company to execute asset sales planned at reducing debt in the current environment.

Analyst upgrades:

• Baird upgraded Buffalo Wild Wings (NASDAQ: BWLD) to Outperform from Neutral following strong Q2 results as they expect comps momentum, operating leverage, and potentially favorable chicken wing costs to support healthy trends in 2H08.
  
• RBC Capital upgraded Myriad Genetics (NASDAQ: MYGN) to Outperform from Sector Perform citing solid core molecular diagnostics growth and increased confidence that the spin-out will generate better shareholder value.

Analyst downgrades:

• Citigroup downgraded shares of Wyeth (NYSE: WYE) to Sell from Hold following the disappointing bapineuzumab data and lowered their target to $39 from $49.
• Molson Coors (NYSE: TAP) was downgraded to Neutral from Overweight at JP Morgan.
  
• UBS lowered Affymetrix (NASDAQ: AFFX) and Sepracor (NASDAQ: SEPR) to Neutral from Buy.

Analyst initiations:

• Banc of America assumed Walgreen Co. (NYSE: WAG) with a Buy rating and $38 target and believes fewer new pharmacies openings removes an impediment to higher ROIC.

Buffalo Wild Wings (NASDAQ:BWLD), an operator and franchisor of 510 restaurants, is expected to report Q2 EPS in late July. BWLD is recently down $2.32 to $27.41. BWLD call option volume of 955 contracts compares to put volume of 4,570 contracts. BWLD July option implied volatility is at 65, August is at 76; above its 26-week average of 56 according to Track Data, suggesting larger price movement into late July EPS.

Some investors shy away from small stocks, thinking they are too volatile and risky. But BusinessWeek takes a look at such stocks and finds some that could offer a lot of potential for growth.

It can be hard to find small companies that have great growth potential. Since most Wall Street analysts ignore smaller companies, it is often tough for investors to find the research that they need in their selection process, so they have to rely on their own research in order to find that perfect small cap stock.

One thing to look for when examining small cap stocks is a long and established track record. The downside to this approach is that these stocks are not going to be the next "big thing" and bring you huge profits in the short run. These stocks are the ones that typically serve a niche market, and perform that service successfully. While these will not make you rich overnight, they are fairly reliable companies you can look to for nice and steady returns. If you are the type of investor who likes to buy and hold, these are the small cap stocks for you.

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

• Archer Daniels Midland Co. (NYSE: ADM) Q3 profits soared, beating analysts' expectations.
• Buffalo Wild Wings Inc. (NASDAQ: BWLD) strong Q1 results met analysts' expectations.
• Burger King Holdings Inc. (NYSE: BKC) reported solid Q3 results that beat Wall Street estimates.
• Chesapeake Energy Corp. (NYSE: CHK) beat expectations for the first quarter, sending shares up.
