Last night, I gave a talk to a group of clients about the strengthening U.S. economic recovery. Interestingly, most of the questions focused on the rest of the world and the risks we face as a result of serious economic issues elsewhere.

I am currently attending a Goldman Sachs conference, and I was struck by one key point made by the agenda: The U.S. is still the center of the world. 

We’ve seen a market downdraft, a bounce back up, and now . . . what next? This is the big question everyone’s asking.

Over the past couple of days, I’ve said again and again that the U.S. is in good shape economically, and that the problems rattling the markets are coming from elsewhere in the world. Today, let’s take a closer look at where we stand, and why I think we're well positioned to ride out any market turmoil.

Once again, the winds of market turbulence are starting to blow. Once again, barometers (and stock prices) are dropping. Once again, we wonder why we ever thought it was a good idea to invest in stocks.

Apart from the stock market—and we got a break on that front yesterday—the big story lately has been falling oil prices.

Not to minimize the market’s losses, but from a long-term perspective, the oil price decline over the past month is the more important story by far, both for the U.S. economy and for the world.

Yesterday was another bad one. The market is now below its 200-day moving average, and the selling toward the end of the day wasn't a good sign.

It’s time to think through what this "correction" might mean.

After I wrote Friday’s post, the market proceeded to drop even further, and it opened today with another dip. Time to reevaluate where we stand.

First, as always, it’s important to keep things in perspective. As I write this, the S&P 500 is down just over 6 percent from the peak. We’re still up about 2.5 percent for the year, and more than 11 percent for the past 12 months. Even with the drop, we’re in a pretty good place.

Over the past few days, the market has taken investors on a roller-coaster ride, and I suspect many of us are feeling a bit queasy. No one likes to be jerked down and up and back down again.

What’s going on?

Yesterday was a bad day for the stock market, which dropped sharply on fears about European growth. So they say, anyway.

Pinpointing a single reason for market moves has always seemed misguided to me, when you think about all the factors behind any investment decision. Even so, taking it at face value, what should we make of European growth and yesterday’s market decline?
