Wednesday, the Fed announced that interest rates would remain at zero to 0.25% for at least the next six months.

The Fed statement read as follows: "weak conditions are likely to warrant exceptionally low levels of the federal funds rate for an extended period." The only change in the Fed's policy was a tweak in the amount of corporate debt that the Fed intends to buy.

Under the radar: Some trends are obvious enough and visible to all investors. Others are more-subtle, but are just as potent, and these often slip 'under the radar.'

Case in point: Saudi Arabia's oil exports to the United States have fallen to a 22-year low, at 745,000 barrels per day (bpd) in August, the latest month for which data is available, from 1.14 million bpd in July, according to data compiled by the U.S. Energy Information Agency. August's 745,000 bpd total is the lowest since December 1987. On a year-over-year basis (August 2008-August 2009), those exports are down about 50%.

U.S. stock futures climbed on Wednesday morning, ahead of the decision by the Federal Reserve on interest-rate and monetary policy. This afternoon, the Fed will give its outlook on the economy and the corresponding policy it's taking. It is widely believed the Fed will not raise rates. Meanwhile, more earnings and economic data are on tap.

Unlike this morning, traders appeared more cautious Tuesday, as the Fed began its two-day policy meeting. Stocks ended mixed and fairly unchanged following news that Warren Buffett's Berkshire Hathaway (NYSE: BRK.B) has decided to buy Burlington Northern Santa Fe (NYSE: BNI) in a deal worth $44 billion and as Johnson & Johnson (NYSE: JNJ) announced a 6-7% workforce reduction.

Bloomberg News took a recent poll of its subscribers. Here are some highlights of the survey:

• Only 31% of investors saw investment opportunities in the stock market, down from 35% in the July survey.
• Worldwide, investors see the U.S. as the weakest link in the world economy. Twenty five percent of respondents see an unemployment rate of 11% in the U.S. next year.
• Respondents see China and India as the most promising markets and commodities are the asset of choice.
• Real Estate and bonds are out of favor, with 40% saying that bonds will have the worst returns over the next year.

Climate change isn't going to be free. A report by Point Carbon, an independent consulting company that tracks global carbon and energy markets, estimates that U.S. climate legislation could push the price at the pump 13 cents a gallon higher. The increase would result from the cost to oil companies for carbon permits, which they can pass along to consumers.

This is a much rosier view than that of the oil industry, however, which believes a U.S. cap-and-trade system would thrash demand for gasoline and lead to the shuttering of many refineries.

"We're adding Brazil's Vale S.A. (NYSE: VALE), the world's leading iron ore producer, to our model growth portfolio," says growth stock expert Stephen Leeb.

In his The Complete Investor, he explains, "This outstanding company offers investors simultaneous stakes in two key areas: iron ore-a commodity essential to any and all infrastructure projects-and Brazil's appreciating currency, the real.

"When it comes to understanding the importance of a commodity such as iron ore, the tale starts with China. Even with China's GDP growth again approaching double digits, the Chinese government continues to aggressively promote growth, offering consumers incentives to buy cars and investing in infrastructure, from roads to bridges to sewers to energy plants.

U.S. stock futures were significantly higher Monday morning, with Wall Street ready to start November on a solid note following Friday's sharp selloff. This morning is indicative of the week ahead full of earnings and economic data. In addition, this week also features the Federal Reserve policy meeting.

On Friday, markets skidded some 2.5 percent as the fate of CIT Group (NYSE: CIT) hung in balance and the strength of the economic recovery, and with it the markets' rally, questioned. And after seven months winning streak, which took Wall Street over 50 percent higher from March lows, October finished in a down note.

Now here's a real important story. If you are an oil trader, chances are you traded the New York Mercantile Exchange West Texas Intermediate (WTI) contract. World pricing of oil by the biggest exporters was based on the WTI contract.

Now, suddenly, Saudi Arabia has decided to drop the WTI contract as the benchmark pricing unit for its oil. It is substituting a contract called the Argus Sour Crude Index, which will track the price in the physical market of a basket of U.S. gulf coast crudes, including Mars, Poseidon, and Southern Green Canyon.

"The U.S. Energy Department is sponsoring a race to develop an obscure industrial process -- carbon capture and sequestration (CCS) -- and the winners of the race will receive $1.4 billion -- yes, billion, with a B," says Andy Obermueller.

In Government-Driven Investing, he says, "My pick to profit from among the 12 companies selected to compete in this scientific 'Olympiad' is Praxair (NYSE: PX)."

"This industrial-gas company owns hundreds of CCS patents, technology that could turn a coal-fired power plant -- about the dirtiest thing in the world, emissions-wise -- into one of the cleanest.

Oil giant Chevron Corp. (NYSE: CVX) will get its chance to impress Wall Street before the market opens Friday when it reports its third quarter results.

The last time the company reported earnings was back in July when it was unable to meet analyst estimates by posting 87 cents per share verse estimates for 95 cents. Traders seem optimistic that the company will meet expectations this time around and are driving the stock up 2.5% in today's trading.

"There is a very interesting situation developing in the oil and gas industry," says Mike Turner. In the Trade of the Week advisory, he looks at the Oil & Gas Ultra ProShares (NYSE: DIG).

"Even though global economies are not rapidly recovering (although they do seem to be on a positive upslope), and even though there seems to be a bit more supply than demand in the energy markets, oil and gas stocks continue to move higher. What's behind this move?

"Oil has become the inverse proxy to the U.S. dollar. As the dollar weakens, the price of oil is moving higher. With the burgeoning debt piling up in the U.S., the dollar looks to be under pressure to move lower for the foreseeable future.

U.S. stock futures declined Wednesday morning a day after stocks mostly fell on mixed economic data and some earnings disappointments. Today is another busy day of earnings and economic releases, including durable goods orders and new home sales.

On Tuesday, U.S. stocks fell for a third straight session after a surprise drop in consumer confidence. Despite a good housing report, and even as the Dow's oil giants and IBM (NYSE: IBM) saved the Dow from finishing in the red (BP (BYSE: BP) on good earnings, and IBM increased its share repurchase plan), tech staged a selloff and the Nasdaq composite fell 1.2%. The S&P 500 fell 0.3%.

"Brazil has long been our favorite of the BRIC countries," says Carl Delfeld. In his Chartwell Global Wealth Letter, the advisor looks at two favored Brazilian equity ETFs.

"Brazil seems to have confounded its critics, who view it as a boom and bust economy; the country has been upgraded to investment grade status by Moody's.

"The US ratings agency cited the resilience of the Brazilian economy to the financial crisis for the upgrade of its sovereign debt ratings one notch to Baa3, its lowest investment grade rating.

"This elevation of quality is well earned after years of reform in the country that led to lower inflation and a stronger currency as well as lower levels of government debt.

BP plc (NYSE: BP - option chain) shares are rising today after the company reported earnings this morning, posting a third-quarter profit of $5.34 billion. Excluding one-time items, BP earned $4.98 billion, easily topping analysts' forecasts of $3.2 billion. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on BP.

BP opened this morning at $57.93. So far today the stock has hit a low of $57.41 and as of 12:00 is trading near its high on the session at $58.63 up $3.15 (5.7%). The chart for BP looks neutral and S&P gives BP a neutral 3 STARS (out of 5) hold ranking.

TheStreet.com's Jim Cramer says perhaps he can learn from Gov. Ed Rendell of Pennsylvania, who has become a believer in the fuel.

Maybe President Obama can make the transition to natural gas that Ed Rendell just did in Pennsylvania. The transition is a simple one: Focus on jobs and many things go well; don't focus on jobs and you aren't focused on anything.

When I first heard of the Marcellus Shale from Aubrey McClendon of Chesapeake (NYSE: CHK) (Cramer's Take), I was pretty much in disbelief. How could there be so much natural gas in some place in western Pennsylvania? Too good to be true.
