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.

John Reese is an expert in analyzing the investment criteria of "legendary" advisors with time-tested strategies. And one market approach that may be of particular interest to investors during the current period of market turmoil is the value strategy developed by Benjamin Graham. (For more on this strategy, see our other post, "Three Rules of Value Investing".)

In his Validea newsletter, John reese explains, "Benjamin Graham -- considered the greatest investment guru by Warren Buffett -- built his reputation by using an extremely conservative, low-risk approach to investing." Buffett, incidentally, was Ben Graham's student.

Reese continues, "To Graham, preserving one's original capital was every bit as important as netting big gains. Having lived through the 1929 market crash, it's no surprise that the strategy Graham laid out in his classic book The Intelligent Investor was a conservative, loss-averse approach.

"To Graham, an investment wasn't something that could be turned into quick, easy profits; anything that offers such 'easy' rewards also comes with substantial risk, and Graham abhorred risk. In terms of specifics, Graham's approach limited risk in a number of ways, and my Graham-based model lays out several of those methods.
