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.

Online marketing specialist ValueClick (VCLK) is scheduled to unveil its fourth-quarter earnings after Tuesday's closing bell. Ahead of the announcement, analysts surveyed by Thomson Reuters are anticipating a profit of 23 cents per share, on average, which would represent an improvement over ValueClick's year-ago earnings of 18 cents per share.

ValueClick has a strong history in the earnings spotlight, having surpassed analysts' bottom-line expectations in each of the past four quarters. However, a quick scan of the stock's sentiment backdrop reveals a nearly palpable pessimism among both traders and analysts.

Cosmetics giant Avon Products (AVP) unveiled its fourth-quarter earnings this morning, and the results fell short of Wall Street's expectations. AVP's quarterly profit slipped 15% to $229.5 million, or 53 cents per share. Excluding restructuring expenses, earnings from continuing operations declined to 59 cents per share from 68 cents in the year-ago quarter. Revenue rose 1.2% to $3.18 billion.

By contrast, analysts were looking for a profit of 67 cents per share on revenue of $3.28 billion. AVP's fourth-quarter performance was negatively impacted by currency fluctuations, as well as higher product costs.

Shares of Level 3 Communications (LVLT) have taken a turn for the worse, after the firm's fourth-quarter earnings report landed with a thud. The company confessed to a net loss of $52 million, or 3 cents per share, narrowed from its year-ago deficit of $182 million, or 11 cents per share. Revenue for the quarter declined to $921 million from $924 million.

The results actually surpassed Wall Street's consensus forecast, which called for a net loss of 10 cents per share on revenue of $920.1 million. However, traders seem none too pleased with Level 3's earnings performance, as the stock plummeted roughly 7% Wednesday morning. In particular, it seems the market may be taking issue with Level 3's warning that it expects free cash flow to be negative for fiscal 2011.

In the wake of Friday's drastic pullback in the stock market, it looks like at least one trader is banking on more short-term volatility. Bright and early Monday, a spread speculator constructed a long straddle on the PowerShares QQQ Trust (QQQQ), with the trader hoping to capitalize on a substantial price swing over the next several weeks.

Specifically, the trader purchased a block of 1,205 February 56 calls, and simultaneously bought a matching block of 1,205 February 56 puts. QQQQ was hovering right at $55.69 at the time of these transactions, placing both strikes very near the money.

Juniper Networks (JNPR) is on the upswing, with the stock catching a 6% boost Wednesday morning on the heels of a well-received fourth-quarter earnings report. Juniper reported a quarterly profit of $190.2 million, or 35 cents per share, substantially improved from its year-ago results of $22.9 million, or 4 cents per share. Excluding items, earnings improved to 42 cents from 32 cents per share on a year-over-year basis.

Meanwhile, revenue for the quarter increased 26% to $1.19 billion. Gross margin retreated slightly, falling to 66.6% from 67.1%.

Blue-chip burger baron McDonald's (MCD) was in focus Monday morning after the company unveiled its fourth-quarter earnings. The fast-food chain reported net income of $1.24 billion, or $1.16 per share, slightly improved from its year-ago profit of $1.22 billion, or $1.11 per share. Revenue for the quarter climbed 4% to $6.21 billion.

The fourth-quarter results were more or less in line with Wall Street's expectations, but the same can't be said of its December sales. Global same-store sales rose 3.7% across the board, led by an 8.9% gain in the Asia-Pacific, Middle East and Africa (APMEA). U.S. same-store sales increased 2.6% in December, while sales at restaurants open at least 13 months declined 0.5% in Europe.

Early Friday morning, Bank of America (BAC) reported a fourth-quarter loss of 16 cents per share ($1.2 billion). This includes the company's previously announced goodwill impairment charge of $2 billion that was related to its home loans and insurance business. Taking this charge out of the equation, BAC earned 4 cents per share. It could be an interesting morning for BAC, as experts predicted earnings of 18 cents per share.

Shares of BAC were down more than 2% as we await the opening bell. This drop should push the stock low enough to mount a serious challenge to the support of both BAC's 20-month moving average and the $14 level.

After the closing bell sounded Wednesday, Seagate Technology (STX) reported its second-quarter results. The tech firm announced that it logged non-GAAP earnings of 33 cents per share ($159 million). The firm's earnings of 33 cents per share matched the consensus estimate, as did the firm's quarterly revenue of $2.72 billion.

STX also reported its performance during the six-month period that ended on Dec. 31, 2010. During this time, the firm's GAAP basis revenue was $5.4 billion, gross margin was 19.9%, net income totaled $299 million, and diluted earnings hit 61 cents per share.

The shares of Nvidia (NVDA) have been tearing up the charts in 2011, thanks to a lucrative settlement with Intel (INTC) and a high-profile new partnership with ARM Holdings (ARMH). The month of January isn't quite half-over yet, but the stock is already sitting on a year-to-date gain of 51.6%.

Judging by at least one headline hitting the wires, the stock's rapid rise is making some analysts nervous. However, on Wednesday, one upbeat options trader placed a bet on additional upside from NVDA during the near term.

LeapFrog Enterprises (LF) plummeted more than 25% this morning, after the company warned that its full-year earnings will fall below Wall Street's expectations. The maker of educational toys expects to bank a profit of 3 cents to 6 cents per share for fiscal 2010, way below analysts' consensus estimate of 28 cents per share.

"After a solid start to the holiday season, demand softened late in the quarter relative to our expectations," explained CEO Bill Chiasson. "While sales of interactive reading products continued to grow at retail, the growth was less than we had forecasted and contributed to lower earnings growth than expected."
