Every day I marvel at all the silly things that happen in the marketplace, the missed opportunities and the overlooked bargains. Mini-mill steel company Nucor Corp. (NUE) is certainly one of them.

I understand that the construction industry is in the dumps and the auto industry has barely come back to life. There is no question that Nucor has fallen on tough times. However, that is what creates the investment opportunity. If you want to make a lot of money, you must find high-quality companies during their business lulls and not be afraid to put your money to work.

In the year following Bush's dividend tax cuts, the Dow Jones rose 16%. When the tax cuts expire in a few months, will the market drop?

One method of evaluating stocks is that they are worth the present value of all the future cash flows. This can make dividend stocks particularly attractive to investors because they get paid rent or a dividend for holding a company. If conditions change and those future dividends are no longer expected, a stock can suddenly be worth a lot less. This is a large reason why we see stocks drop suddenly at earnings announcements or when companies revise outlooks.

United States Steel Corp. (X), whose colleagues include AK Steel (AKS) and Nucor Corp. (NUE), was sold off by investors on Tuesday after the company released its first-quarter results. The stock dropped $3.44, or 5.7%, to $56.63. Volume was strong.

The company is definitely far away from the 52-week low, but it unfortunately is also significantly under the 52-week high of $70.95. The one-year chart shows an up-and-down pattern that isn't necessarily for every investor. Indeed, the most recent price action has been decidedly in the downward direction. Of course, that might mean the business is worth a look, especially when you take into account the ultimate bias towards an upward trend. Let's check out the Q1 numbers.

A new method of setting the price on iron ore for export is upsetting Chinese and European steel makers and auto manufacturers, but that same pricing scheme is most likely going to benefit U.S. steelmakers such as AK Steel (AKS), Nucor (NUE) and U.S. Steel (X).

In the past, iron ore pricing was largely set on an annual basis, with the first negotiated ore contracts of the season setting the price for the duration of that season. However, this year, the three largest iron ore miners, BHP Billiton (BHP), Rio Tinto (RTP) and Vale SA (VALE), have decided that they will seek quarterly renegotiation of ore contract pricing. This will allow those companies to take better advantage of increases in iron ore demand and spikes in spot prices.

TheStreet.com's Jim Cramer says at least one country is getting it right when it comes to economic stimulus.

How in the heck can you get 16% industrial growth and lower-than-expected consumer price inflation? How is that possible? Yet that's what we saw from China last night, and that's a tonic to pretty much everyone who is waiting for our own stimulus to kick in.

And we need it.

On Monday, Fluor (FLR) (Cramer's Take), the giant construction company, when asked if it could quantify the value of stimulus dollars currently in backlog, said "Really, the only stimulus funding we have seen directly has been the award that we got at Savannah River for some nuclear soil remediation. And, it was, I would say, we're less than $0.5 billion."

TheStreet.com's Jim Cramer says the relentless ascent can only point to a belief that Congress will put jobs on the front burner.

Washington's listening. I think that Washington has had its fill of health care talk and is anxious to focus on jobs. President Obama wants to dither now with carbon capture, content that the stimulus plan, however bogus it was, is doing the job. But Congress senses that they are 13 months from a debacle and they are going to bring employment to the front burner.

That's what I think the market is saying. When I spoke to Dan DiMicco last night, the CEO from Nucor (NUE) (Cramer's Take), he showed devastating evidence of the real unemployment, now at about 18%, and the lack of job creation coming out of this recession compared to the last four recessions.

Where on earth can you buy things on sale for less than bargain prices?

Imagine that you were shopping for a nice shirt, or watch, or bicycle and you have been tracking the prices all year (or ten) and the thing finally goes on sale. You drive to the store and while you are in transit, unknown to you, the store manager puts a half price sticker on the item. You would be overjoyed with glee! To buy something at half the price you already thought was a bargain -- that would be amazing!

The fact is that this year the stock market has provided that opportunity. This year for the first time in most of our lives, you were able to do that to a degree that we have not witnessed before and have only read about.

Nucor (NYSE: NUE - option chain) shares are rising today after iron-ore miner Rio Tinto (NYSE: RTP) agreed to cut its iron ore prices for Japan's Nippon Steel Corp by more than 30%. The steelmakers have already been driven lower as demand for their product has slowed, but now they are less likely to be charged boom-time prices for their raw materials on top of that. 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 NUE.

NUE opened this morning at $39.44. So far today the stock has hit a low of $39.14 and a high of $41.41. As of 11:35, NUE is trading at $41.25 up 1.16 (2.9%). The chart for NUE looks bearish and S&P gives NUE a negative 2 STARS (out of 5) sell ranking.

The whole world watches China when it comes to the natural resource play. Iron ore and steel companies have watched their share prices swing wildly based on news coming out of the Middle Kingdom in terms of what Chinese mills will be buying and how much they are willing to pay (particularly for the annual iron ore negotiations). Of late, the steel and iron sector has bounced nicely based on rising Chinese demand. Now noises coming out of China's government imply the steel bounce might have been inflated demand numbers.

TheStreet.com's Jim Cramer says this market is short-term overbought -- any other reasons to buy can wait.

The playbook says, "Buy weak-dollar plays." But does that mean only weak-dollar commodity plays, as in flee-out-of-dollar-into-oil plays? Or weak-dollar plays like Johnson & Johnson (NYSE: JNJ) (Cramer's Take) and General Mills (NYSE: GIS) (Cramer's Take)? Or weak-dollar plays like gold? Or tech plays because Intel (NASDAQ: INTC) (Cramer's Take) and Hewlett-Packard (NYSE: HPQ) (Cramer's Take) are hugely international?

Or do you bother doing anything at all up here because we are plus-seven on the oscillator and every time we have gotten this overbought in this market, we have come crashing down?

TheStreet.com's Jim Cramer says if the pricing shows a disconnect with long-term truths, you can buy here.

Nothing to say. Not much going on. Can't get any CEOs to comment. Too close to the end of the quarter. People are dismissive of Nucor (NYSE: NUE) (Cramer's Take), and happy with Darden (NYSE: DRI) (Cramer's Take). Meanwhile, Tim Geithner's been silent, and silence is golden. Now if only he would ask one simple question: What are we guaranteeing with AIG (NYSE: AIG) (Cramer's Take)? It's a sideshow but an important one down the road, not now.

All of these things are of a piece. We are in one of those golden moments when not much is happening, and when we get information, we declare it half-full. I found myself thinking that Nucor's decline has to be some sort of a bottom because utilization rates don't get much lower than this. I found myself thinking that the infrastructure plan will kick in because everyone has now decided it will and that's all that matters.

Back in 2001, Jim Collins had a monster of a business bestseller with his book Good to Great: Why Some Companies Make the Leap. . . and Others Don't. In it, Collins explored companies that have become hugely successful and found that success generally comes as a result of focusing resources on things that you're good at instead of mindlessly diversifying.

Arkansas Business writer Jeff Hankins read the book again to see how the companies profiled have weathered the downturn. The companies profiled were Abbot Laboratories (NYSE: ABT), Kroger (NYSE: KR), Kimberly-Clark (NYSE: KMB), Walgreens (NYSE: WAG), Altria (NYSE: MO), Nucor (NYSE: NUE), Pitney Bowes (NYSE: PBI), Wells Fargo (NYSE: WFC) and tragically, Fannie Mae and Circuit City. Gilette was eliminated from contention because of a merger.

TheStreet.com's Jim Cramer says the importance of this nation cannot be overstated.

How long before we start feeling the positive effect of a market that is up 13% and is the biggest user of commodities? How long do we think oil can stay down (or copper or steel) when the stock market of China, the growth engine, is no longer sputtering and has ample room to run?

As people sell down BP (NYSE: BP) (Cramer's Take) and Conoco (NYSE: COP) (Cramer's Take), they simply must believe that the Chinese stimulus plan is already a failure. Anyone on the Mattel (NYSE: MAT) (Cramer's Take) conference call -- talk about a company with Chinese insight -- certainly thinks so. The description of China from reports like Mattel is one of Cormac McCarthy's The Road-like devastation.
