Shares of The Boston Beer Company (NYSE: SAM) surged to a new 52-week high Friday morning, after the brewmaster reported a third-quarter profit of $10.4 million, or 72 cents per share, on revenue of $108.7 million. The company swung to a loss of 2 cents per share in the third quarter of 2008, but attributed its turnaround to strong shipments and decreased advertising expenses.

The results were better than analysts expected, with consensus estimates calling for Boston Beer to bank a profit of 39 cents per share on $107.5 million. Looking forward, Boston Beer now expects full-year earnings of $1.75 per share to $2.05 per share, a marked increased from its prior forecast for a 2009 profit of $1.40 per share to $1.70 per share.

Traders initially seemed thrilled with Wednesday's third-quarter earnings report from Lumber Liquidators (NYSE: LL), but the stock then backpedaled into the red.

Revenue for the period surged 14% to $140.5 million. The results comfortably outpaced analysts' consensus estimates, which called for a profit of 24 cents per share on $137.1 million in revenue.

Looking ahead, Lumber Liquidators is forecasting full-year revenue of $535 million to $543 million, up from its previous guidance of $528 million to $538 million. Earnings for fiscal 2009 are expected to range between 90 cents and 95 cents per share, compared to the retailer's previous forecast of 85 cents to 91 cents per share.

A report in Thursday's The Wall Street Journal [subscription required] reveals that American International Group (NYSE: AIG) is actually reaping the benefits of its risky bets in the credit-default swap market.

AIG was forced to shell out billions to Wall Street banks amid last year's credit crisis, as the assets backed by the credit-default swaps plummeted in value. However, the market's reversal of fortune means that banking heavyweights, such as Goldman Sachs Group (NYSE: GS), are now returning collateral to the infamous insurance giant.

LDK Solar Co., Ltd. (NYSE: LDK) was broadly higher Tuesday after boosting its top-line guidance for the third quarter.

Wall Street is cheering the latest earnings report from Costco Wholesale Corporation (NASDAQ: COST), with the shares adding more than 3% within the first hour of trading. This morning, as Tom Johansmeyer reported, the wholesale club reported a 6% slide in fiscal fourth-quarter earnings, but the results nevertheless exceeded analysts' expectations.

In the wake of COST's report, analyst Brian Sozzi of Wall Street Strategies reiterated his Buy rating and $66 price target on the equity. "In our view, 4Q09 will go a long way in supporting a higher valuation for Costco," wrote Sozzi in a research note this morning. "The company has managed to control costs, drive traffic to its warehouses consistently throughout the economic downturn, paid $300 million in annual dividends in FY09 (payout ratio of 26.0% second to only Wal-Mart in the sector), and has catalysts on the horizon to showcase earnings power above currently modeled for consensus EPS."

Heading into the report, analysts are expecting PEP to bank a profit of $1.02 per share, according to Thomson Reuters, fractionally lower than its year-ago earnings of $1.06 per share.

PepsiCo has a healthy history in the earnings spotlight, having exceeded Wall Street's consensus expectations in each of the previous three quarters. Judging by recent option activity, traders are speculating on another upside surprise from the Frito-Lay firm.

Hovnanian Enterprises Inc. (NYSE: HOV) announced Monday morning that it will sell up to $775 million (WSJ subscription required) of seven-year notes in order to fund its previously reported tender offer for up to $759.3 million in debt. The struggling homebuilder also reported that $877 million of the notes were tendered by the early deadline on Friday. As a result, Hovnanian reduced the maximum amount of unsecured notes it will buy from $130 million to $100 million.

Last week, a Wall Street Journal article noted that Hovnanian is "hobbled" by its debt, even as the rest of the industry is ready to buy up land at a bargain. As of July 31, Hovnanian's net debt accounted for 109% of total capital, compared to an average of 26% for the dozen major homebuilders tracked by research firm Zelman & Associates.

Bright and early this morning, Goldman Sachs downgraded gaming guru Activision Blizzard (NASDAQ: ATVI) from Conviction Buy to Buy. In a note to clients, the brokerage firm explained that it sees greater relative potential for near-term price appreciation in other stocks. Goldman maintains a six-month price target of $16 on ATVI, implying expected upside of more than 29% from the shares' closing price on Wednesday.

ATVI is a ripe target for downgrades, if only because analysts are so lopsidedly optimistic toward the "Guitar Hero" parent. Zacks reports that the equity has attracted no fewer than 18 Strong Buy recommendations, plus two Buys -- with not a single Hold, Sell, or Strong Sell to be found.

Late Thursday, McDonald's (NYSE: MCD) announced a 10% increase to its cash dividend. The fast-food firm will now shell out 55 cents per share each quarter, bringing its total quarterly dividend payout to roughly $600 million.

In other MCD news, Bernstein initiated coverage of the stock with an "outperform" rating. The brokerage firm likes McDonald's because of its broad global footprint, with Bernstein noting that restaurants more heavily dependent on the sluggish U.S. market could struggle.

"The government's CARS, or 'cash for clunkers,' program resulted in a spike in traffic in late July and August," explained CEO Tom Folliard. Same-store used-unit sales for the quarter climbed 8%, bouncing back from a 17% drop in the first quarter.

BioCryst Pharmaceuticals (NASDAQ: BCRX) was on the move Tuesday after inking letters of intent with three partners, who will take the lead on stockpiling, marketing, and distribution efforts for the company's influenza treatment in four countries.
