Last week, JA Solar Holdings Co. Ltd. (NASDAQ: JASO) posted a quarterly loss and lowered its guidance. But as interest in alternative energy continues to grow, analysts polled by Thomson Financial are still looking for good things from solar energy concerns scheduled to report earnings this week.

Strong growth at Trina Solar Ltd. (NYSE: TSL) in the third quarter prompted it to lift its guidance back in October. Analysts expect the Chinese company to post profits that are 76.3% higher than a year ago, or $1.18 per share on revenues of $268.4 million (+225.0%). Though Trina Solar missed estimates in the second quarter, analysts on average recommend buying TSL. Shares are down 81.4% from a year ago and trading near an all-time low.

Earnings of rival LDK Solar Co. Ltd. (NYSE: LDK) are expect to have risen 47.9% to $0.71 per share on revenues of $486.7 million (+206.6%). Also based in China, LDK has not missed estimates in recent quarters; in fact, it blew past expectations in the second quarter. Yet the consensus recommendation is to hold LDK. Like Trina Solar, LDK's shares are trading near an all-time low; the share price has fallen 50.0% in the past year.

Analysts anticipate third-quarter earnings for Canadian Solar Inc. (NASDAQ: CSIQ) to be a whopping 96.3% higher than a year ago, or $0.54 per share on revenues of $248.0 million (+154.5%). The company easily topped estimates in the previous quarter. ReneSola Ltd. (NYSE: SOL) and Suntech Power Holdings Co. Ltd. (NYSE: STP) are also expected to report earnings growth of 29.7% ($0.37 per share) and 23.8% ($0.42 per share), respectively. All three of these stocks reached 52-week lows last week, and all are considered buys.

This post is part of a series on some of the most memorable companies that have disappeared.

The story of Trans World Airlines is the story of American capitalism in the 20th century. Founded by aviation pioneers and scrappy entrepreneurs, TWA became one of the largest and most successful airlines in the world. It racked up numerous awards and distinctions and created a devoted base of customers and employees. Along the way, it also displayed the twisted corporate history typical of capitalism American-style, with plenty of buyouts and mergers and awkward transitions. Finally, it ended up the victim of vulture capitalists, who picked it clean and sold its carcass to a competitor. All in all, a heckuva ride.

The company got its official beginning in 1930, when Transcontinental Air Transport and Western Air Express merged to form Transcontinental & Western Air (T&WA). The merger was driven by one of the great motivators in American free market capitalism: the pursuit of lucrative government contracts. In this case, the contracts were for airmail transport and the new airline was soon rolling in federal dough, though not for long. The great Air Mail Scandal of 1934 brought an end to that arrangement and the airlines split up, although the name lived on.

From 1930 forward, TWA experienced some dramatic ups and downs. After a TWA crash killed Notre Dame coach Knute Rockne in 1931, the airline nearly went out of business. It survived though and went on to pioneer the use of many of the great aircraft of the 20th century, including the first (and only) DC-1, the Boeing Stratoliner, and the Lockheed Constellation. TWA also built some beautiful buildings, including the famous terminal at JFK in New York designed by Eero Saarinen. And TWA gained some noteworthy owners and managers along the way, most famously the reclusive though aircraft obsessed Howard Hughes, who lost control of the airline when his effort to upgrade to jets in the 1950s hit some financial turbulence.

MOST NOTEWORTHY:

• Citigroup upgraded shares of National Financial Partners (NYSE:NFP) to Buy from Hold on valuation, as they believe the recent weakness is overdone. Citigroup also added the stock to their Top Picks Live list.
  
• Jefferies upgraded shares of Blackbaud (NASDAQ:BLKB) to Hold from Underperform on valuation, as they believe management did the right thing by lowering guidance while buying back stock more aggressively.
  
• B. Riley lifted Trans World (NASDAQ:TWMC) to Buy from Neutral as they believe the company could ultimately go private should credit conditions improve

• Keefe Bruyette raised Anworth Mortgage (NYSE:ANH) to Outperform from Market Perform.
  
• Unit Corp (NYSE:UNT) was upgraded at Raymond James to Outperform from Market Perform.
  
• RBC Capital upgraded Brandywine Realty Trust (NYSE:BDN) to Sector Perform from Underperform.

On November 19th, I reported that Sherwood Investments, an investment manager purporting to own a 4.34% stake in Trans World Entertainment (NASDAQ: TWMC) had put out a press release announcing its opposition to CEO Robert Higgins' proposed buyout of the company at $5 per share.

Now, Sherwood Investments has upped the ante, putting out another press release offering to buy the company for $7 per share, disclosing a 4.95% stake in the company.

The stock soared on the news, closing at $5.76, a rise of nearly 16%. But I think investors should react to the "news" with a good deal of skepticism.

MOST NOTEWORTHY: The U.S. banking sector, HSBC Holdings, Trans World and Mips Technologies were today's noteworthy downgrades:

• CIBC downgraded the U.S. Banks sector to Underweight from Market Weight as they see another leg down as investors shift focus away from write-downs to the impact the write-downs will have on risk-weighted assets and capital ratios.
• Morgan Stanley downgraded shares of HSBC Holdings Plc (NYSE: HBC) to Equal Weight from Underweight, as they believe the company may have to set aside more money for bad loans in the U.S.
• B. Riley downgraded shares of Trans World Entertainment Corporation (NASDAQ: TWMC) to Neutral from Buy, as they believe the downside risk should the Bob Higgins acquisition proposal fall through outweighs the potential upside should the bid be raised or should another bidder emerge.
  
• B. Riley also downgraded Mips Technologies Inc (NASDAQ: MIPS) to Neutral from Buy following the company's Q1 results to reflect the company's deteriorating balance sheet and licensing business softness.

• Lehman downgraded Federal National Mortgage Association (NYSE: FNM) and Federal Home Loan Mortgage Corporation (NYSE: FRE) to Equal Weight from Overweight.
• Bear Stearns downgraded Wyeth (NYSE: WYE) to Peer Perform from Outperform.
