There were three major economic reports last week, which gave us a look at the service sector, trade, and—most important—the job market. The week ahead will be a busy one, with five major reports expected.

February’s data continued to be quite good. We saw improvements in many areas, particularly in employment, suggesting continued and possibly accelerating growth into 2018. Job growth jumped substantially, coming in well above expectations, and both consumer and business confidence remained at very high levels. Fed policy continues to be stimulative, and recent increases in long-term rates steepened the yield curve—often a positive sign. Overall, this month’s strong economic data indicates that the weakness at the end of 2017 has passed, although policy remains a concern, particularly around trade.

I woke up this morning to a surprise. It had snowed, which was expected. After all the fear-mongering coverage, in fact, I expected the house to be covered, but it wasn’t so bad. The real surprise was the fact that a combination of wind and heavy snow had taken down several trees—including an 18-footer right across most of my driveway. All of a sudden, I was cut off.

Yesterday, I wrote that the markets were likely to continue to trend upward, on the idea that the U.S. tariffs were not really going to happen. But then the news that Gary Cohn had resigned as head of the National Economic Council was announced—and this has changed that perception entirely.

Well, that was quick. After a sharp but short pullback in late January/early February, the market started to rally again. But it was derailed by the announcement—by the U.S. president—of an impending trade war. Then, after an even shorter and less sharp pullback, it seems to have started to rally again (although it is slightly down as I write this). What’s going on?

As the bull market reaches its ninth year, what will it take to actually bring it down? Or will the market continue to rise? I discussed this and more earlier today on CNBC's Power Lunch.

There were five major economic reports last week, which gave us a detailed look at both the consumer and manufacturing. This week, we’ll see three major reports, which will give us a view of the service sector, trade, and the job market.

February was an eventful month for the markets. There was a 10-percent market drawdown in the U.S., something we haven’t seen for almost two years. Although many were worried that this was the “big one,” the markets recovered more than half of their losses by month-end, and the economic fundamentals remain sound.

Yesterday, President Trump announced that the U.S. will be imposing tariffs on steel and aluminum imports. This shocked markets here in the U.S. and around the world, driving them back down just as it looked like they were recovering from the downturn last month. What happened? And is this a more serious threat going forward? In a word, yes.

As we head into March, I thought it would be a good time to take an economic snapshot—by looking back at February and at what we might expect in the month ahead.
