Yesterday, we talked about how the U.S. government deficit, while improving, is still way too high, posing serious problems for the future. Today, I want to touch on two other problems that you might think have been solved—but haven’t.

Part of the return to normal for the economy and the financial markets has been a decline in interest—or at least media coverage—of the national deficit and debt.

Though understandable, this is a mistake, as the deficit and debt remain a serious problem for the country in the medium to long term.

Following up on yesterday’s post, I want to look at two areas of the investment world that have a lot to say about how we invest our money—and how we make our profits.

One of the keys to business success is sustainable advantage, often referred to as a competitive “moat.” In short, if you have something your competitors can’t duplicate, you can charge for it and make money.

The idea typically centers on things that protect products. Think of patents, or the kind of ecosystem of software, hardware, and content that Apple, Amazon, and Google are building, at a cost of billions of dollars.

Yesterday, I wrote that banks starting to lend again is a plus for the economy. Today, I want to take a closer look at a key assumption underlying that statement.

Much of modern society revolves around consumption, and there's nothing wrong with that—if it’s affordable. If not, we find ourselves in 2009 again.

The real question here is what affordable means. In fact, this is the question at the core of saving, investing, retiring, and pretty much everything else I write about here. 

The headlines today are all about the deal between Bank of America and the government. After months of negotiation, the bank will pay about $17 billion to resolve allegations that it didn’t follow the rules for residential mortgages before the financial crisis. 

No company likes to pay out billions of dollars, and BofA had a good case that it didn’t do nearly as much wrong as the government claimed. (Many of the allegations involved actions committed by companies that the bank acquired at the government’s urging during the crisis.) Nonetheless, the BofA deal should be a good thing for the bank—and the rest of America.

Learn why I told CNBC Worldwide Exchange that I think the Fed's tapering of its bond-buying program is a good thing for the financial sector in an interview today, August 7. 

When I go on vacation, I do so with the expectation that something will happen that makes me (almost) want to be back in the office.

Sure enough, while I was out last week, the market proceeded to sell off in a way that has become pretty uncommon recently, generating fear and worry.

In my latest Market Thoughts video, I talk about the U.S. economy, international turmoil, and the U.S. market's performance at the end of July.

It’s time for our monthly update on factors that have proven to be reliable indicators of economic trouble ahead.

As expected, the data hasn’t changed that much from last month—it’s encouraging in almost all areas—but it remains important to keep an eye on things.
