I'm reiterating my Buy rating for 3M Co. (NYSE: MMM), first recommended on April 20, 2009 at a price of $51.97. If you bought 3M in April, you're up an impressive 46%.

Way back in the spring, I argued, among other factors, that a strong case for buying 3M shares could be made based on the company's large free cash flow and net returns on capital, and reasonable P/E (then about 11), before everyone else jumped on the bandwagon.

Well, with a current P/E of about18, 3M is no where near as cheap, but I still like the shares here, around $75.

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

• AirTran Holdings Inc. (NYSE: AAI) reported its third consecutive quarterly profit and will increase capacity.
• Amazon.com Inc. (NASDAQ: AMZN) shares soared after it reported very strong Q3 numbers.
• Apple Inc. (NASDAQ: AAPL) reported stellar Q4 results, driven by the popularity of Macs and iPhones.
• BlackRock Inc. (NYSE: BLK) Q3 earnings soared, due in part to a tax benefit, and assets managed grew.
• Broadcom Corp. (NASDAQ: BRCM) revenue surged sequentially but note the would be flat going forward.
• Caterpillar Inc. (NYSE: CAT) beat Q3 earnings expectations and shares rose though revenue slumped.

3M (NYSE: MMM) is one of those solid stocks that investors love to sock away in a core portfolio. It was down when pessimism about the economy was at its peak, but it's coming back now that Wall Street is becoming comfortable with the idea that the economic clouds will eventually give way to rays of macro sunshine.

Earlier in the week, 3M reported a great quarter. No, it wasn't so great on a comparable basis. The company, which counts Johnson & Johnson (NYSE: JNJ) and DuPont (NYSE: DD) as colleagues, suffered a decline of almost 6% on the top line in Q3. Earnings per share on an adjusted basis, which came in at $1.37 per share, were down 3.5%.

Markets rose substantially at the end of the day, in part led by the strong earnings reports from 5 of 30 DJIA components this morning alone. This was despite the discussions of the risks of the US's Triple-A rating, another drop in home prices, and despite weekly jobless claims heading higher.

Here were today's unofficial closing bell levels:

Dow 10,081.31 +131.95 (1.33%)
S&P 500 1,092.91 +11.51 (1.06%)
Nasdaq 2,165.29 +14.56 (0.68%)

Top 10 Analyst Calls

TheStreet.com's Jim Cramer says that as long as we're trapped in a commoditized stock market, use the futures to go bargain-hunting.

What if individual stocks want to go up, but the market wants to go down? Don't laugh. In 1982, when The Kansas City Board of Trade started trading Value Line futures (before there were S&P futures), we used to kick around in securities classes what would happen if eventually stocks became so commoditized that individual companies couldn't be removed from the gravitational pull.

For example, we know today looks like a terrible day, with Europe down horribly and our futures real soggy. But then we look and see that J. Crew (NYSE: JCG) (Cramer's Take), one of the best retailers, is not just saying that the fall season is good; it is saying it is blowout beyond imagination. The big Dow stock 3M (NYSE: MMM) (Cramer's Take) is not just saying that things are getting better; it is showing that business is very strong. The monster insurer and fellow Dow stock Travelers (NYSE: TRV) (Cramer's Take) is boosting the dividend and showing you how a responsible financial can behave.

TheStreet.com's Jim Cramer says the weak dollar is benefiting U.S. corporations and no longer going against them.

Why have the industrials been so red-hot? Why do they seem to levitate? One reason, of course, is that people think the economy's getting better. A second reason is that even if the economy stands still vs. last year the comparisons will be amazing and nothing gets the juices going more rapidly than easy comparisons.

Why will they be so glaring? First, the layoffs have been brutal, the cost-cutting immense and it hasn't hurt at all ... yet. It is totally and unequivocally positive.

TheStreet.com's Jim Cramer says the action that is linked to the futures markets, such as oil, is distorting rational analysis.

Maybe one day we can escape the commodity linkage and begin to trade on the fundamentals again, something that seems more distant now than any time I can recall. We are totally marching to gold, to oil, to copper, and not the fundamentals.

Throughout the era in which China has become a superpower and hedge funds have become the super arbiters or what goes up or down, we have been stuck with this fairly bogus linkage that corrupts trading and makes a mockery out of some of the most important financial analysis out there, the actual attempts to discover what's really happening at companies.

TheStreet.com's Jim Cramer says takeover deals and major stock upgrades are going to be hard to fight.

Worldwide funded freight train coming at you. Hard to fight. Hard to stand in front of. That's what I think is happening here. It is clear that Ron Insana, in his fabulous Market Movers commentary this morning and with his quick moves to catch some of the move, totally agrees with me. It doesn't take much to see that Doug Kass is going full bore against me.

I feel like Michael Corleone in the lamented Godfather III. Every time I want to get out, they pull me back in again, and this time the pull is from the macro, where the central bankers keep plowing the money in, and from the micro, where one of the biggest deals in ages -- the Kraft (NYSE: KFT) (Cramer's Take) hostile on Cadbury -- reminds us that stocks aren't expensive, they are cheap.

What are auction rate securities? How did these securities cause billions in losses to investors and businesses?

Auction rate security, according to Wikipedia, "refers to a debt instrument (corporate or municipal bonds) with a long term maturity for which the interest rate is regularly reset at a dutch auction."

Throughout the 1990s and up to 2008, bank loans became more expensive. As a result, ARSs became increasingly attractive. They were lower in cost and flexible for variable rate debt. Auctions were typically held every 7, 28 or 35 days.

So what happened to cause such big losses?

TheStreet.com's Jim Cramer says if you wait for market conditions to reach perfection, you'll be waiting a long time.

You know what? I am going to wait until I am sure housing has turned before I buy the homebuilders like Lennar (NYSE: LEN) (Cramer's Take) and Pulte (NYSE: PHM) (Cramer's Take). I am going to wait until the foreclosures peak before I buy Bank of America (NYSE: BAC) (Cramer's Take) and Wells Fargo (NYSE: WFC) (Cramer's Take).

I am going to wait until unemployment goes down before I buy 3M (NYSE: MMM) (Cramer's Take) and Disney (NYSE: DIS) (Cramer's Take) and IBM (NYSE: IBM) (Cramer's Take) and Caterpillar (NYSE: CAT) (Cramer's Take).

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

• AK Steel Holding Corp. (NYSE: AKS) posted a smaller-than-expected Q2 net loss as steel prices rise.
• Boston Scientific Corp. (NYSE: BSX) posted a better-than-expected Q2 profit on strong overseas sales.
• Caterpillar Inc. (NYSE: CAT) shares jumped after it beat earnings, missed revenues, and offered guidance.
• DuPont (NYSE: DD) shares declined after it posted a higher-than-expected profit but lower revenue.
• Eaton Corp. (NYSE: ETN) disappointing results were a sign that the bulls are in charge, said Jim Cramer.
• General Electric Co. (NYSE: GE) Q2 earnings and sales declined, dragged down by finance and NBC units.

U.S. stock futures rose on Thursday morning after Ford reported a surprise earnings and following some mergers-and-acquisition activity. Another fresh wave of earnings releases awaits investors today, as well as jobless, homes data.

Ford Motor Co. (NYSE: F) surprised Wall Street this morning when it posted a profit in the second-quarter of $2.3 billion due mainly to a huge gain for debt reduction. While Ford would have reported a loss of $424 million, or 21 cents per share, without special items, the loss is still far smaller than the 50 cents analysts had expected.

TheStreet.com's Jim Cramer says he counts at least six Democrats who won't fall in line -- this bill hasn't a chance.

Everyone's fretting about the new tax brackets -- or at least everyone who's rich or who lives in a high-tax state -- over the health care plan coming out of Congress. Everyone thinks that Nancy Pelosi can never be defeated. She is a juggernaut. More powerful than a speeding bullet. Etc.

But the Senate could be a different story. Remember Pelosi and co. need 60 votes, and there are exactly 60 Democrats. There are two publicly quoted Democratic senators who are not even the most likely biggest objectors -- Sen. Ben Nelson from Nebraska and Sen. Evan Bayh from Indiana.

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

• Amazon.com Inc. (NASDAQ: AMZN) reported strong Q1 results easily beat expectations.
• Bank of America Corp. (NYSE: BAC) posted better-than-expected Q1 earnings, helped by home refinancing.
• Caterpillar Inc. (NYSE: CAT) reported its first quarterly loss since 1992 and cut its revenue outlook.
• Coca-Cola Co. (NYSE: KO) posted Q1 earnings that were in line with expectations, but shares fell.
• eBay Inc. (NASDAQ: EBAY) posted better-than-expected Q1 earnings despite a decline in sales.

3M (NYSE: MMM) had a not-that-great first quarter. The declines were significant and ugly. First, net sales plunged over 20%. Second, net income on an adjusted basis likewise spiraled out of control, declining over 40% to $0.81 per share. And no, that didn't meet expectations. Wall Street was looking for $0.86 per share. Sorry, gang.

You've got the dollar and the global recession to blame. Currency translations affected sales, and declines in economic activity didn't help much, either. Many people look to 3M as a staunch dividend play. As such, cash flow is important. Unfortunately, the statement of cash flows this quarter was hard to read. Net cash from operations decreased 30%, and free cash flow lost 35% of its value when compared to the year-ago period. Thankfully, there was enough free cash to cover the dividend.
