Here are some highlights from last week's earnings coverage from BloggingStocks:

• Aetna Inc. (NYSE: AET) said its profit fell due to higher expenses and warned the trend may continue.
• Avon Products Inc. (NYSE: AVP) topped Q2 earnings expectations, which sent shares higher.
• ConocoPhillips (NYSE: COP) lower Q2 earnings topped expectations, but revenue was also down.
• DreamWorks Animation Inc. (NYSE: DWA) posted flat Q2 earnings as it waits for the next big DVD release.
• First Solar Inc. (NASDAQ: FSLR) posted a better-than-expected profit but guidance sent shares lower.
• Jacobs Engineering Group Inc. (NYSE: JEC) Q3 revenue missed estimates and it lowered its outlook.

Jacobs Engineering Group (NYSE: JEC - option chain) stock is falling today after the company reported third-quarter earnings last night of $94.90 million or 76 cents per share, on revenue of $2.71 billion. Analysts had expected a profit of 75 cents per share on revenue of $2.83 billion. JEC also reduced its fiscal-2009 EPS guidance to a range between $3.10 and $3.35, down from a previous range between $3.10 and $3.50. Analysts are looking for EPS of $3.29. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on JEC.

This morning, JEC opened at $40.10. So far today the stock has hit a low of $39.62 and a high of $40.86. As of 12:00, JEC is trading at $39.81, down $3.58 (-8.2%). The chart for JEC looks bullish and S&P gives JEC a positive 5 STARS (out of 5) strong buy ranking.

What's the next bubble? Perhaps it's the global spending on infrastructure.

No doubt, there will be some big-time winners, especially large engineering companies. One example: Siemens AG (NYSE: SI), which is the largest engineering operator in Europe.

Interestingly enough, the company said that – over the next three years – it will win about $21 billion in projects from the stimulus bonanza. Something else, roughly 40% of the projects will involve environmental technologies.

TheStreet.com's Jim Cramer says after seeing what was passed, forget the infra plays.

Is President Obama listening to all of those good businesspeople around him? Or is it all being done for show? Did they really get behind that stimulus package that couldn't stimulate a fraction of the jobs that have already been lost this month?

I couldn't help but feel that way after speaking to Dan Dimicco from Nucor (NYSE: NUE) (Cramer's Take) last night. Nucor's had about a 50% drop in production of steel -- the kind of steel that would be used in any real infrastructure package -- and he was simply aghast that anyone could check off on anything that small, that the amount of steel that would be used in that package was minuscule and wouldn't mean a thing.

It is very easy to make money in this market despite the headlines. Using options to capitalize on volatility combined with a long/short strategy can result in powerful returns.

For example, taking equal positions of my Top 10 Stocks for 2009 while at the same time selling equal amounts of my Top 10 Stocks to Avoid would generate a return of more than 10% year to date.

Given that trends once in place stay in place for some time, I am quite confident that these positions will be winners throughout the year. It is not too late to set up your trades using these suggestions as a guide.

Do not underestimate the power of a new administration in Washington. With the ability to spend a huge amount of dollars, team Obama can wield tremendous influence in the market.

Case in point is the stem cell space. It is widely expected that Obama will issue an executive order eliminating restrictions on stem cell research.

Stocks like StemCells Inc. (NASDAQ: STEM) and Geron Corp. (NASDAQ: GERN) have been moving higher since the inaugural.

Coincidentally, on Friday, GERN announced approval for human trials for its treatment of spinal chord injuries using stem cells. Both GERN and STEM were up big as a result.

Another space expected to do well under the Obama administration is construction. A massive stimulus plan is said to be coming in February. A key point of the plan will be to boost infrastructure spending.

The dollars will benefit companies like Fluor Corp. (NYSE: FLR) and Jacobs Engineering (NYSE: JEC). Unlike stem cells, the market has yet to move these stocks higher. FLR is down more than 10% and JEC is down nearly 18% so far this year.

"Infrastructure stocks have been laid low by the economic downturn; but once massive government stimulus programs get growth going again, these companies should be among the surest winners," says Stephen Leeb.

In The Complete Investor newsletter, the advisor explains, "We've found four top infrastructure stocks, now at bargain-basement levels, that we think will surge. All are all astonishingly cheap when you consider how vital their role is in worldwide economic growth."

"It would be difficult to find a group of stocks more leveraged to economic growth yet whose valuations imply there will be no growth.

"If you have any faith in the world's future, these stocks are for you, and we think they will be dramatic outperformers as stimulus spending starts to kick in.

"Most diverse among the four is Jacobs Engineering (NYSE: JEC), which serves the chemical, pharmaceutical, building/infrastructure, and oil and gas industries. Nearly 20% of its revenues come from government sources, domestic and foreign.

"The company has nominal debt and has been generating hefty free cash flow, which management has indicated it may use to acquire beaten-down compatible firms, adding to future growth.

TheStreet.com's Jim Cramer says that we need to build up our reserves so the wild fluctuations can't happen again.

Memo to Barack Obama: Start building oil facilities right now -- tankers, tanks, whatever. Fill up every preserve you can. This is the time to buy oil for America even if you don't like carbon footprints.

The new president is being given a once-in-a-lifetime infrastructure opportunity to build enough tankers and tanks to sop up the supply. That's what is needed more than anything. We can't drill for these prices economically anymore, and oil is obviously overflowing everywhere. Right now, we are out of storage in this country. That's one reason the price has fallen so precipitously -- there is nowhere to put it. I don't think there is a soul who believes that oil will be down here two years from now. We should be filling and creating a strategic petroleum reserve that is big enough that this will never happen again. NEVER.

That ridiculous run-up that everyone says was caused by speculators must not occur again, as we see the disastrous results. We need to be able to bring oil down ourselves by buying reserves at these prices and making them available to beat the speculators next time this occurs. I think the low price is because of the big pension and endowments funds puking up their commodity exposure because they can't sell a lot of other investments they are locked into, including private equity.

In the biblical story, Jacob dreams of a ladder connecting heaven and earth. Ever since, boys named Jacob have gravitated toward careers in engineering (anecdotally of course).

That is certainly true in the case of Joseph Jacobs, who founded Jacobs Engineering Group (NYSE: JEC) in 1947. This Jacob did indeed excel in building things.

Now, with the economy in shambles, his engineering firm is poised to benefit from the soon-to-be-approved stimulus spending targeted toward infrastructure and energy projects.

With the goal of creating 2.5 million jobs during the first two years of his administration, President-elect Obama plans on attacking the recession with Legos. That means companies that provide anything to do with construction can be expected to do very well.

The company's profile reads like a blueprint for where a lot of the money from the government will be flowing under the Obama administration. JEC provides technical, professional and construction services to industrial, commercial and governmental customers around the globe.

It is involved in energy, transportation and education projects. The company is in the sweet spot of where an awful lot of spending will take place in the next few years, and investors in JEC stand to benefit.

In the days of trading since the President-elect announced his plan, JEC is up more than 23%. Impressive gains no doubt, but given the selling that took place earlier, JEC shares still offer compelling value.

Now that Senator Obama is President-elect Obama, what will he do with the economy and how can you profit from it? One way is to look for stocks that will benefit from a part of his proposed economic stimulus plan -- the creation of a National Infrastructure Reinvestment Bank that would spend $60 billion over 10 years on roads, bridges, ports, airports and rail lines.

One company that could benefit from this investment would be Jacobs Engineering (NYSE: JEC), which engineers municipal infrastructure. The stock is down 57% in the last year due to concerns about whether states and cities will build new infrastructure in the face of a crumbling economy. But does the Jacobs' stock drop mean it will go up now that Obama is President?

If its earnings estimates are credible, I would say Jacobs could be a good investment. That's because the stock trades at a Price/Earnings to Growth Ratio (PEG) of 0.55 and a stock whose PEG is below 1.0 looks undervalued to me. Jacobs' 0.5 PEG is based on a P/E ratio of 11.4 on earnings growth of 20.8% to EPS of $4.05 in the fiscal year ending September 2009.

And if Obama enacts his infrastructure plan in 2009, Jacobs' earnings prospects could brighten even more.

TheStreet.com's Jim Cramer says the safety theme will come back if only because these companies' earnings will be good in six months.

Now they come after the Procter & Gambles (NYSE: PG) (Cramer's Take) and the General Mills (NYSE: GIS) (Cramer's Take) and the like, betting that the action will be better in the cyclicals with all of this money being printed worldwide.

Commodities are also coming back because of reflation. And we have to feel that many of the infra and ag names are finally sold out by the hedge fund redemptions.

Here I am speaking of a Freeport McMoRan (NYSE: FCX) (Cramer's Take), with its good yield and a belief that the hedge funds are at last done.

I don't buy it. I like a balanced portfolio, but I want to buy the GIS/PG all the way down because we are going into a recession, not going out of one. These companies pay dividends, raise dividends and have great commodity tailwinds.

Colgate's (NYSE: CL) (Cramer's Take) down a lot too, and I am liking that one.
