"No US utility owns more of them than Exelon Corp. (NYSE: EXC), with 17 reactors," explains Roger Conrad, who chose the stock as his latest "growth spotlight" in The Utility Forecaster.

"Carbon free and, above all, paid for, existing nuclear plants are among the most prized assets in the power business.

"Some 80% of company earnings come from its unregulated generation fleet, 90% of which is nuclear. And it's by far the best-positioned US utility to ramp up nuclear output.

• Merriman upgraded OptionXpress (NASDAQ: OXPS) to Neutral from Sell following the company's better than expected Q2 results. The firm notes higher commissions per trade more than offset weak DARTs and the decline in customer additions in the quarter.
• RBC Capital upgraded Gardner Denver (NYSE: GDI) to Outperform from Sector Perform and raised its target to $34 from $28 citing the additional scale of restructuring, better tone to end-markets, and few downside catalysts.

The dealmaking is heating up in the nuclear sector. Today, Exelon Corp (NYSE: EXC) upped its hostile bid by 12% for NRG Energy (NYSE: NRG). This new price tag translates into a valuation of $7.45 billion.

The wrangling between the companies has gone on for roughly eight months. In fact, hostile deals can be time-consuming (in some cases, lasting a couple years).

Something else: Exelon has indicated that this is the "best and final offer." Apparently, the company has realized new cost savings, which justifies the higher valuation.

TheStreet.com's Jim Cramer says that Dominion Resources saw a lot of the green movement coming and moved aggressively.

What do you do with a company that raises its dividend twice in two years by 11%, that has superior growth characteristics in its sector, enlightened management and a plan for executives to buy stock regularly?

Well, in this market, that's an easy question to answer: You sell it. That's what's been going on with Dominion Resources (NYSE: D) (Cramer's Take), the Richmond, Va.-based utility that yields more than 6%, but is bumping along its 52-week low like every other stock I follow.

U.S. stock futures were higher Monday morning, indicating stocks could rise at the open after China Sunday announced a $585 billion stimulus package, which includes tax cuts and infrastructure spending. This cause world markets to climb as well as commodities. Oil followed stock markets and jumped above $64 a barrel. Another boost to stocks was further aid from the government to AIG.

[Update 8:25: Circuit City Stores Inc. (NYSE: CC) filed for bankruptcy. Shares are down 52% in premarket trading to 12 cents.]

American International Group (NYSE: AIG) -- The government on Monday provided new financial assistance to the troubled insurance giant, including pouring $40 billion into the company in return for partial ownership. Altogether, AIG got around $150 billion. AIG shares are shooting up over 21% in premarket trading.

General Motors Corp. (NYSE: GM), Ford Motor Co. (NYSE: F) and Chrysler are also moving closer to a bailout as Obama's chief of staff, Rahm Emanuel, called the industry an "essential" part of the U.S. economy. House Speaker Nancy Pelosi and Senate Majority Leader Harry Reid said that the administration should consider expanding the $700 billion financial industry bailout to include car companies. With this kind of support, still undecided is the size and timing of any aid. GM shares are up 2.3% (it was hit by a downgrade from Barclays) and Ford shares are up nearly 5% in premarket trade. [Update 9:10: as expected, with the GM downgrade, it is down over 10% in premarket trading, Ford is only slightly down thought]

NRG Energy Inc. (NYSE: NRG) on Sunday rejected an unsolicited $6.1 billion all-stock bid from nuclear power giant and utility operator Exelon Corp. (NYSE: EXC), calling it too low. NRG shares jumped 6.8% in premarket trading.

TheStreet.com's Jim Cramer says you can game the psychology of the market if you want, but know the rules.

I see the plan: Every day that the market looks like it is going down we give $10 billion to some bank! It is sure-fire. Did you notice the momentary weakness in France Monday? Quick, cut checks to BNP, SocGen and Agricole. Why not? When ING (NYSE: ING) (Cramer's Take) looked like it was a disaster, giving $13 billion to that one-time conservative bank turned all of Europe around!

Monday, when there was a moment that we looked weak, when it looked like we were going to go from plus 200 to below 100, Treasury let it be known that there is a whole other round of checks coming for the second-tier players. Who knows? Boom. That plus higher oil prices turned the market around in the upside-down world we are now in! No doubt soon Downey (NYSE: DSL) (Cramer's Take) and BankUnited (NASDAQ: BKUNA) (Cramer's Take) might get checks and then everything will go higher.

Oh, and on top of that, we have a new stimulus plan, one specially designed, no doubt, to move Target (NYSE: TGT) (Cramer's Take) back to its moving average and get Macy's (NYSE: M) (Cramer's Take) off the critical list.

Today was another strong day in the market, which may be mostly credited to Ben Bernanke giving a carte blanche for another economic stimulus package in his testimony this morning. We saw a rise in California home buying, but that was credited to foreclosure purchases at far lower prices.

Below are today's unofficial closing bell levels:

Cisco Systems Inc. (NASDAQ: CSCO) traded higher by about 2% in pre-market after its rating was raised to Outperform from Market Perform at Morgan Keegan. The firm believes orders are holding up better than many suspect. Another reason for the upgrade was forward valuation levels. Shares closed up almost 6% at $18.96 today.

Exxon Mobil Corp. (NYSE: XOM) traded up 10% today to close at $74.99 as part of a broad oil-sector upgrade at Oppenheimer after recent weakness, and as oil prices recovered throughout the day.

TheStreet.com's Jim Cramer says this is the first real deal to take advantage of the new low prices of this era.

Editor's note: Jim Cramer will present his 2009 stock outlook for the first time at TheStreet.com Investment Conference on Saturday, Oct. 25. Limited seating. Act now.

The Exelon (NYSE: EXC) (Cramer's Take) bid for NRG Energy (NYSE: NRG) (Cramer's Take) is what we need to see if we are going to find terra firma. We need to see healthy companies with good balance sheets going after other healthy companies that have balance sheets that won't let them do well.

If there were no credit crunch, NRG -- like Constellation Energy (NYSE: CEG) (Cramer's Take) before it -- would be doing just fine. In fact, you would be wondering what the heck it was doing so low. Reliant Energy (NYSE: RRI) (Cramer's Take) and Mirant (NYSE: MIR) (Cramer's Take) also fit the same pattern. These are all companies that need ready access to capital, and it doesn't exist right now.

NRG has a pro-nuke history and so does Exelon. Nuclear power has taken on an almost holy image in this country if the plants are already built because you simply can't afford to build new ones. NRG is one of the few utilities in the whole country that is trying to build plants, something that would be fabulous for Exelon and NRG's shareholders alike. It's a great match.

Exelon (NYSE: EXC) offered to buy NRG Energy (NYSE: NRG) for $6.2 billion or 0.485 of an EXC share for each NRG shares, which is worth about $26.43 for each NRG share. EXC, the biggest U.S. operator of nuclear power plants, closed at $54.50. EXC November option implied volatility of 75 is above its 26-week average of 75 according to Track Data, suggesting larger price movement.

NRG, a generation company with annual revenues of $5.9 billion, closed at $19.33. NRG November option implied volatility of 133 is above its 26-week average of 42 according to Track Data, suggesting larger price movement.

Volatility Index S&P 500 Options-VIX at 70.33; 10-day moving average is 61.44.

Analyst downgrades:

"To say that alternative energies are critical is a severe understatement." asserts Stephen Leeb, who looks at three plays in the sector that earn a spot in his Growth Portfolio.

The editor of The Complete Investor explains, "Readily scalable energy sources such as solar and wind account for under 1%. It's time to get serious."

Three of the stocks he has selected are holdings in his model Growth Portfolio: FPL Group (NYSE: FPL), Exelon (NYSE: EXC), and General Electric (NYSE: GE). Here's a trio of favorites.

"We have focused on those alternative energy stocks with the strongest growth profiles. None is a pie in the sky fantasy; all provide energy in the here and now and have significant and fast-growing revenue streams.

"The fact that their growth should continue to burgeon is one of the most heartening pieces of news on the energy front. We could argue that investing in these stocks not only will be good for your portfolio but is an act of patriotism as well.
