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.

Shares of Patriot Coal (PCX) surged to a new annual high of $27.54 right out of the gate Tuesday, as traders cheered the energy issue's latest quarterly report.

Patriot announced that its fourth-quarter net profit dwindled 33% to $7.3 million, or 8 cents per share, from its year-ago results of $10.9 million, or 12 cents per share. Revenue for the quarter climbed 5% to $528.2 million, but selling and administrative expenses swelled 35% to $14 million. Likewise, Patriot's operating cost per ton increased 9.5% to $55.70.

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."

Thursday morning, GPS specialist Garmin Ltd. (GRMN) said it lost a patent dispute with Japanese firm Pioneer Corp. The District Court of Dusseldorf in Germany found that two patents owned by Pioneer were infringed by a certain functionality in Garmin's software.

However, Garmin says it has already worked out "minor software revisions that eliminate the narrow functionality at issue in the litigation." As a result, the company doesn't expect any significant impact on its ability to import and sell its navigational products.

Shares of Cumberland Pharmaceuticals (CPIX) are having a rough go of it after the Food and Drug Administration (FDA) outlined some concerns that will further delay a ruling on its liver drug. The regulatory agency already postponed its decision from August to December, and now the FDA says it needs additional data before it can recommend the drug for approval.

In its complete response letter to Cumberland, the FDA noted insufficient evidence to prove that the injectable drug, Acetadote, is effective in all patients. Cumberland said it plans to meet with the FDA soon to address the outstanding issues.

Shares of Netflix (NFLX) started Tuesday on a high note, with the shares gaining more than 1% out of the gate. Traders appear to be responding to new comments from Jim Cramer, after the host of CNBC's Mad Money offered an upbeat opinion on the stock Monday.

Specifically, Cramer is enthusiastic about Netflix's push into streaming content, and he has high expectations for future subscriber growth. The analyst also argued that the stock's valuation is actually quite reasonable, when measured against the company's long-term growth rate. For traders looking to take part in continued gains by NFLX, Cramer suggested in-the-money call options.

Call options were in heavy rotation Monday on The Gap (GPS). Within the first hour of trading, 3,350 of these bullishly oriented options crossed the tape -- about four times the expected number of call contracts. The bulk of this activity took place at The Gap's January 2011 22.50 call, where 3,031 contracts were traded. Approximately 77% of these calls changed hands at the ask price, indicating they were purchased.

However, this skew toward calls simply continues a recent trend for GPS. During the past 10 days, speculators on the International Securities Exchange (ISE) have bought to open 5.99 calls for every put on the retailer. This ratio ranks above 75% of other such readings taken during the previous year, indicating that traders on the ISE have purchased calls over puts at a faster pace just 25% of the time.

Lennar Corp. (LEN) just can't seem to win much respect on Wall Street. Despite well-known fundamental issues within the housing sector, LEN has tallied a year-to-date advance of roughly 35% -- easily topping the 11.4% gain collected by the S&P 500 Index (SPX).

Wall Street seems less than impressed by this technical outperformance, though. Earlier today, S&P Equity downgraded the stock to hold from strong buy, joining six other analysts who maintain a tepid rating on the shares.

American Superconductor (AMSC) gapped lower right out of the gate this morning, thanks to a bearish write-up in Barron's (subscription required) over the weekend. In a piece titled "Flagging Winds from China," author Bill Alpert warns of "signs that China's boom in wind power is slowing." As points of concern, Alpert points to dropping prices and rising inventories in the wind-turbine industry.

AMSC tumbled to a loss of more than 6% Monday morning, deepening its year-to-date decline of 18%. The stock has suffered four consecutive Friday closes beneath its 10-week moving average, and AMSC is now trading below its 20-week moving average, as well. Going forward, these formerly supportive trendlines could switch roles to act as resistance.

Diamond Foods (DMND) was on the upswing Thursday, as traders cheered the company's latest earnings report. Diamond said it banked a fiscal first-quarter profit of $14.2 million, or 64 cents per share. Excluding items, earnings arrived at 65 cents per share, while revenue increased 40% to $252.6 million.

The results comfortably exceeded Wall Street's expectations, which called for a profit of 60 cents per share on revenue of $239.8 million.

Lululemon Athletica (LULU) will take its turn in the earnings confessional bright and early tomorrow morning, Dec. 9. Analysts are expecting the athletic apparel firm to report a third-quarter profit of 25 cents per share, up from 20 cents per share in the year-ago period. LULU has an impressive track record in the earnings spotlight, having exceeded Wall Street's consensus profit expectations in each of the past four quarters.

The stock has also established itself as a technical outperformer, with LULU rising 82.5% so far in 2010. This impressive ascent has been underlined by reliable support at the stock's 10-week, 20-week, and 50-week moving averages, which have guided LULU higher since July 2009.

Tax specialist H&R Block (HRB) is slated to take the earnings stage tonight, with Wall Street anticipating a fiscal second-quarter loss of 38 cents per share -- right in line with the firm's year-ago deficit. HRB has been a solid performer on the earnings front, as the company has surpassed analysts' bottom-line expectations in each of the past four quarters.

Judging by today's option activity, traders are anticipating another upside surprise from HRB. Within the first two hours of the session, no fewer than 13,000 calls crossed the tape -- absolutely dwarfing HRB's average daily call volume of just 4,012 contracts.

Television titan TiVo (TIVO) will step into the earnings spotlight after tonight's closing bell, with Wall Street looking for a third-quarter loss of 17 cents per share -- wider than TiVo's year-ago deficit of 6 cents per share. The firm has been on a hot streak with its quarterly reports, having exceeded analysts' consensus earnings expectations in each of the last three reporting periods.

However, the equity's technical performance isn't quite so impressive. The shares took a dive earlier this month after TiVo's patent dispute with EchoStar (SATS) and Dish Network (DISH) took an ugly turn in the courtroom, and the stock has yet to recover.

Mela Sciences (MELA) gapped higher right out of the gate Monday, with the shares surging roughly 12% on Monday morning. Over the weekend, Barron's noted that the stock is "worth a close look ahead of a regulatory vote on Nov. 18," and traders are apparently taking the suggestion to heart.

The financial publication described its opinion on the shares as "cautiously optimistic," explaining that analysts believe MELA could double if its MelaFind device receives the OK from a Food and Drug Administration (FDA) panel this Thursday. However, warned Barron's, a regulatory thumbs-down "could cut the shares in half."

Level 3 Communications (LVLT) burst higher right out of the gate Thursday morning, as traders cheered the company's new streaming deal with Netflix (NFLX). Level 3 said it has been chosen as a primary content delivery network provider for Netflix, with the company providing support for streaming movies and TV shows. Additionally, Level 3 will store Netflix's entire streaming content library beginning Jan. 1.

This announcement confirms speculation that started swirling earlier in the week, when rumors hit Wall Street that Netflix was looking to ditch its content delivery deal with Akamai Technologies (AKAM). Shares of Akamai slipped about 3% Thursday morning, even though Netflix said earlier it would "continue to engage Akamai as part of our multivendor strategy."
