January was a tough month. We started with a U.S. attack on an Iranian general (creating thoughts of war) and ended with the possibility of a new global pandemic (with the Wuhan coronavirus spreading around the world). In between, of course, we had the impeachment spectacle here in the U.S., as well as the British exit from the European Union. All in all, it was quite a difficult month from a news perspective. Which made it somewhat odd that markets were not hit harder than they were.

Tomorrow, we get the big one, the most (in my opinion) significant economic report of all: the jobs report. So, what should we expect?

From retail sales to housing, we're seeing a real rebound in the economy. I discussed this and more yesterday on CNBC’s Power Lunch.

The idea behind the old adage “as goes January, so goes the year” is this: if the market closes up in January, it will be a good year; if the market closes down in January, it will be a bad year. In fact, it is one of the more reliable of the market saws, having been right almost 9 times out of 10 since 1950. Last year, January saw gains of 7.9 percent for the S&P 500 (the best January since 1987), predicting a very good year. Indeed, that is just what we got.

The year started with a slight setback, with both U.S. and international markets down. Some of this poor performance was driven by fear over the coronavirus. Although the virus is something to watch, it's not likely to be a long-term risk. Indeed, economic growth in the U.S. has been steady, and business and consumer confidence have improved.

Yesterday I appeared on Yahoo Finance’s On the Move to discuss the impact of coronavirus on the market. Listen in to hear more.

Two Fridays ago, the S&P 500 hit its closing record. About two weeks ago, the Dow cracked 29,000 for the first time. At the time, the headlines were all about how high the markets could go—and how quickly. But after the past couple of days, with the markets experiencing renewed volatility, we’ve started hearing much less about the new stock market records. Instead, the headlines are all about the risks, which certainly include the coronavirus, but also the impeachment trial and Brexit.

After years of drama, headlines, predictions of doom, multiple elections, and so forth, we are finally (almost) there: Brexit day. On Friday, the British flag will be lowered outside European Union (EU) buildings as Britain formally exits the union. And so the post-Brexit world will begin.

One of the potential disruptors of the generally positive economic news surfaced in the form of a viral outbreak in China last week. Known as the coronavirus, as of this morning, there were 895 cases in mainland China (mostly in the Wuhan area) and 26 deaths, for a mortality rate of less than 3 percent. There were also at least 20 other cases around the world, including 1 case here in the U.S. The comparison that is being made is to the last major new disease from China, SARS, in 2003.

With the recent signing of the phase one trade deal with China, the sense has been that everything is all set, and we can now move on. There is some truth to this belief, as the deal is better than nothing. Still, the agreement leaves many issues unresolved and even creates some new ones.
