After yesterday’s terrible performance—with U.S. stock markets down more than 2 percent—worries are starting to rise. Combined with last week’s declines, it looks like we may be seeing the end of the bull market. So, is it time to panic?

Last week’s data was focused on prices, although we also got an update on the trade balance. This week is a busy one, including looks at retail sales, consumer confidence, and the housing sector.

It’s time for our monthly look at market risk factors. Just as with the economy, there are several key factors that matter for the market in determining both the risk level and the immediacy of the risk. Although stocks have largely recovered from their recent pullback, given valuations and recent market behavior, it is useful to keep an eye on these factors.

After a difficult quarter, April’s data showed signs of meaningful improvement. Job growth bounced back, easing a major concern. Plus, consumer confidence improved, which should help growth going forward. On the other hand, business confidence dipped further, and the yield curve remains close to a risk level.

When we see sharp drawdowns in the stock market like we have over the past couple of days, it’s natural to worry it might be the start of something much worse. Indeed, it could be. Odds are, however, that this will be a brief pullback followed by a rebound.

April was the month that everything turned around . . . we hope. Job growth kicked back to very high levels, taking the unemployment rate to a 50-year low. Consumer confidence rebounded in a big way. And, perhaps as a consequence, retail spending also came in well above expectations. On top of all that good news, economic growth came in well above expectations for the first quarter—even as the Fed stepped back from its hawkish stance, leaving interest rates unchanged and likely to remain that way.

Last week was a very busy one for economic data, with a number of key reports. This week’s data is focused around prices, but there will also be an update on the trade balance.

On the face of it, this morning’s strong jobs number should elicit a full three cheers. Job growth came in at 263,000. This result was up from last month’s downwardly revised 189,000 and well above the expected 190,000. Looks like a home run, right? In fact, when you dig into the details, the news (while still good) is not nearly as good as the headline suggests. That is why I am subtracting a full cheer from the headline.

April was another great month for the financial markets, as U.S., emerging, and developed markets were all in the green. Although there were concerns about a slowdown at the end of last month, first-quarter economic growth actually came in well above expectations. Plus, consumer spending picked up, consumer confidence bounced back, and business investment came in stronger than expected.

Today we will take a look at an old investing adage: “sell in May and go away.” It is supposed to reflect the idea that market returns over the summer and fall are worse than those in the winter and spring. Under this theory, you should sell all your stocks in May and then buy them back in November.
