"Although some people may think it inappropriate, our job is to make readers aware of opportunities as they occur," says Glenn Rogers.

The contributing editor to Internet Wealth Builder explains, "Invariably, every major crisis creates such opportunities although they may only be suitable for aggressive investors. This one is no different.

"The question is: where to begin? Usually the best place to start is by looking at some of the securities that were hardest hit by the big sell-off that followed the disaster.

"Few people know exactly how long it will take Japan to recover and rebuild, nor the full impact of the destruction in the world's third-largest economy," says Louis Basenese.

The contributing editor to Investment U advises, "In the short term, expect volatility to be the norm; but if you're a long-term investor there are reasons for bullishness:

"First, Japan is cheap. Even before the earthquake hit, Japan was one of the world's cheapest markets with the average stock on the TOPIX trading at a price-to-book ratio of 1.0 -- a 56% discount to the average U.S. stock.

I am maintaining a buy recommendation on Shaw Communications (SJR) despite an underwhelming year-end financial report.

I originally recommended Shaw in my Internet Wealth Builder newsletter on Feb. 4, 2008 at $20.64. Calgary, Alberta-based Shaw, is a telecommunications company, which dominates the rich Alberta market. It recently also purchased the bankrupt CanWest Global television empire. Shaw is a low-risk company that won't suddenly shoot up in price but that compensates with limited downside, steady cash flow, and long-term growth potential.

"The global nuclear power industry is in the early stages of a multiyear growth spurt similar to what the industry experienced in the late 1970s and '80s," says energy sector expert Elliott Gue.

The editor of The Energy Strategist explains, "The nuclear renaissance will generate tremendous wealth for investors over the next few years. Two stocks that will benefit are Cameco (CCJ) and Shaw Group (SHAW).

"The nuclear power industry benefits from both a lack of dependence on imports as well as costs that don't vary excessively with commodity prices.

"Industrials stocks focus on the manufacturing, transport and construction of physical goods and heavy infrastructure," says Elliott Gue.

The contributing editor to Personal Finance explains, "The best in the sector share one key trait: powerful leverage to a global economic recovery led by growth in the emerging markets and renewed spending on basic infrastructure across the developed world. The S&P 500 Industrials has outperformed the broader market by 20% during the past year."

TheStreet.com's Jim Cramer says eventually, the credit markets will thaw, and this one will take off like a rocket.

Cheap isn't always relative. Consider the case of Shaw Group (NYSE: SGR) (Cramer's Take), the infrastructure play with the nuclear bent that has tons of business around the world building nuke plants that are competitive with oil and nat gas even at these prices, but obviously are much better for the environment.

Shaw's doing great -- big order book, no cancellations or stretch-outs (unlike ABB (NYSE: ABB) (Cramer's Take) or McDermott (NYSE: MDR) (Cramer's Take)), and most important, its stock is trading a mere dollar and a half above its cash.

It's absurd, as the CEO told me last night on a pre-empted edition of the 6 p.m. "Mad Money." The valuation makes no sense.

TheStreet.com's Jim Cramer says this report highlighted where the success lies in this market: energy and petroleum.

Fluor's (NYSE: FLR) (Cramer's Take) a monster. It shows you that what has hurt the other companies, particularly Chicago Bridge & Iron (NYSE: CBI) (Cramer's Take), is pure execution.

This gigantic beat also serves to remind us of the big dichotomy. You are either in the energy and petroleum products game or you are in a lot of games that don't work.

It's not easy for these companies, some of which have lived off the duress of state and local governments, including Shaw (NYSE: SGR) (Cramer's Take) and to a certain extent Aecom (NYSE: ACM) (Cramer's Take) and URS (NYSE: URS) (Cramer's Take), to become oil-and-gas plays.

The only ones that have transcended it beside Fluor are Foster Wheeler (NASDAQ: FWLT) (Cramer's Take) and Jacobs Engineering (NYSE: JEC) (Cramer's Take), and the only reason you would really know that is longevity. I remember in the early 1980s when FLR and then FWC would compete directly for all of the huge projects after the second oil shock.
