Best Buy (BBY) is scheduled to unveil its fourth-quarter results Thursday morning, with analysts anticipating a profit of $1.85 per share -- little changed from the big box retailer's year-ago earnings of $1.82 per share. Best Buy has been hot-and-cold on the earnings front; during the past four quarters, the company has topped consensus bottom-line estimates twice, and fallen short on two other occasions.

Ahead of the quarterly report, one options player built a bullishly biased spread on BBY. Right after the opening bell Wednesday morning, the trader purchased 358 April 32 calls, and simultaneously sold 716 April 35 calls. In other words, two April 35 calls were sold for every one purchased April 32 call. This strategy is known as a ratio call spread, and it's typically used by traders who are bullish on the underlying equity -- but with a very specific upside target in mind.

When it comes to credit-card businesses, I'm partial to Visa, Inc. (V). Even so, I have to give my respect today to Discover Financial Services (DFS). At the time of this writing, the stock was up 4.5% to $23.26. Volume was strong. Furthermore, a new 52-week high of $23.46 was recorded earlier in the day (by the time this is published, it's possible the high quote will be different).

The stock has been a good holding over the last twelve months. The 52-week low is $12.11, and the one-year chart shows strength. This name is heading for a double. Is it too late to buy?

Adobe Systems (ADBE) closed Tuesday at $32.88. The 52-week low for the shares is $25.45 and the 52-week high is $37.30. That puts the stock roughly in the middle of the range, which isn't here nor there.

I usually like a quote to give me as much information as it can. I can usually tell more about the market's opinion if the price is closer to either the low or the high, and if the range isn't so tight.

Walgreen (WAG), Dollar General (DG) and Express (EXPR) all reported higher quarterly profits Tuesday morning, with Dollar General and Express both beating Wall Street consensus earnings estimates. With news like this, it may be beneficial for an investor to take a closer look at the retail sector.

Granted, Walgreen did not impress Wall Street, and shares fell more than 7%. Express and Dollar General, however, are reaping the benefits with Express trading up over 5% and Dollar General enjoying a 3% upswing. Both companies opened trading up in the markets Tuesday.

On Wednesday, General Mills (GIS) will report earnings results for the fiscal third quarter. The cereal maker is expected to do okay. According to Earnings.com, net income is projected to be around 56 cents per share. If the company hits that number, then it will represent a decent bottom-line growth rate.

The stock has a couple things going in its favor. The 52-week high is currently set at $38.98. Shares closed on Monday at a price of $37.12, not far from the peak. In addition, the dividend yield of 3% is attractive.

Tiffany & Co. (TIF - option chain) shares are rising after the company reported Q4 2010 earnings Monday morning, posting a profit of $181.22 million, or $1.41 per share. Excluding one-time items, Tiffany earned $1.44 per share on revenue of $1.10 billion, while analysts had forecast a profit of $1.39 per share on revenue of $1.10 billion.

Tiffany cut its Q1 earnings forecast to 57 cents per share, down from a previous forecast of 62 cents per share, due to an anticipated decline in sales in Japan in the wake of the recent earthquake. However, that is still above analysts' forecasts of 55 cents per share, which is a good sign for the stock. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on TIF.

Quarterly reports from Oracle (ORCL), Discover (DFS) and Tiffany (TIF) will highlight news on the earnings front this week.

Elsewhere on the economic calendar, the focus will be on housing, with existing home sales data due from the National Association of Realtors on Monday, new home sales numbers from the Census Bureau on Wednesday and data on housing starts released on Thursday.

Also watch for durable goods orders in February and the final GDP for the fourth quarter.

Earlier in the week, I exhibited a bearish tone on Ross Stores (ROST). I haven't had a change of heart necessarily, but I do have to concede that the company's latest earnings report, issued yesterday morning, was a good one.

According to Reuters, Q4 net profit increased 18% to $1.37 per share. While this number merely met Wall Street's projection, I enjoyed the growth rate. Furthermore, same-store sales experienced a healthy 4% expansion.

Nike, Inc. (NKE) is doing horribly this afternoon. As I write this, a quote of $77.51 is on my screen. That represents a drop of over 9% for the shares. Volume is huge. Hopefully many of you out there didn't do an earnings trade on this one.

How bad were the fiscal Q3 numbers? According to MarketWatch, net income of $1.08 per share was four pennies below the overall call by Wall Street. In addition, the potential for a weakening gross margin is said to have played a part in the sell-off.

Package delivery giant and economic bellwhether FedEx Corp. (FDX) reported Thursday that its third-quarter earnings fell 3% to $231 million, or 73 cents per share, due to rising fuel prices and harsh winter weather.

FedEx also warned that earnings for the current quarter and the entire year could be reduced by the ongoing unrest in the Middle East, and that it's too soon to estimate the affect of the earthquake and tsunami in Japan.
