TheStreet.com's Jim Cramer says both oil futures and equity futures can move these hot issues.

Will the futures pull down the oil and gas stocks today? No, I don't mean the oil futures, I mean the equity futur

Last week when oil exploded, we caught two days of trading that dropped the stocks hard. We caught a bit of a bid in the nat gases like Chesapeake (NYSE:CHK) and Devon (NYSE:DVN) but at the end of the day, but the stocks were truly overwhelmed by the simple fact that they are in the indices.

This pattern has really held down the integrateds: last week Conoco (NYSE:COP) should have exploded, but it couldn't because it is such a big part of the S&P. Chevron (NYSE:CVX) and Exxon (NYSE: XOM) are no different.

The natural gas stocks are not as big a factor, but they can be rocked down without a problem.

I am not saying to avoid looking at the oil futures. They can control the stocks. I am saying that the equity futures tide can take down anything, even when the oil futures spike hard.

MOST NOTEWORTHY: Allied Capital, ZIX Corp and Staples were today's noteworthy initiations:

A DealBook piece looks at David Einhorn's very public battles with Allied Capital (NYSE: ALD) and Lehman Bros. (NYSE: LEH), both of which he is short and accused of accounting chicanery. Einhorn's willingness to "talk his book" has generated controversy. Steven Davidoff writes that "Many short plays are enhanced through rumor and innuendo spread by those self-same shorts. Needless to say, these whispers are sometimes unfounded but can do real harm to a company's share price and the company itself."

In his email newsletter, fund manager Whitney Tilson slams this comment: "Hmmm... How many is "many"? More than one? A majority? 99% of the rumor and innuendo in the market I see is on the long side! The shorts I know, on the other hand, perhaps because they're often falsely accused of spreading "rumor and innuendo", bend over backwards to be open and factual."

This is exactly the point. What is the ratio of "pumps" to "bashes"? When Einhorn goes on CNBC and trashes a stock, it's a national story. That's because it's incredibly rare for anyone to go on CNBC and slam a company. The extent of the skepticism we usually hear in the financial media is "overvalued" or "tough prospects."

So I say to Einhorn and Co.: Keep doing what you're doing. Differing opinions, and especially unpopular ones, make for a better market.

David Einhorn has one of the better money management track records of anyone in the business and has also made headlines with his efforts to expose alleged fraud at Allied Capital (NYSE: ALD). If you haven't read his book on that company, it's probably the best investment title of the year.

Einhorn recently sat down for an interview with TheStreet.com (you can watch it below). He's long Target (NYSE: TGT) and Microsoft (NASDAQ: MSFT) but is still short some of the badly beaten down financial stocks and credit rating agencies. He's bearish on stocks that are trading at high multiples in anticipation of a second-half recovery, something he is "not so sure about."

Of the 50+ business-related books I read each year, maybe 15 were worth reading, in retrospect. Then another five of those are memorable -- in a good year. Hedge fund manager David Einhorn's book Fooling Some of the People All of the Time leapfrogs both of those categories, and establishes itself as a classic of business writing.

The story behind the book is intriguing. It's actually amazing that it ever got published, and tremendous credit should be given to Wiley for taking a chance with such an unconventional tale. Here's the deal: In a 2002 speech at a charity event, Greenlight Capital hedge fund manager David Einhorn gave a speech at a charity event. Asked to talk about his favorite investment idea, he spent 15 minutes explaining why he believe that Allied Capital (NASDAQ: ALD) was a financial crime in progress, ripping off investors and taxpayers as a Small Business Administration lender. Einhorn presented compelling evidence of aggressive accounting and indeed fraud, and disclosed that he was short the stock.

The speech made headlines and the stock tanked. Over the past six years, Einhorn has continued to beat the drum against Allied Capital, presenting information to regulators, reporters, and investors.
