The Automatic Data Processing private sector jobs report showed nonfarm employers added 175,000 jobs in January, lower than analyst expectations of 189,000 jobs and below than December's downward revised 227,000 jobs. ADP had previously estimated the private sector added 238,000 jobs in December.

The private sector jobs report gives economists an advance idea of how the government's main jobs report will turn out. Analysts expect the Labor Department on Friday to report that the public and private sectors added 190,000 jobs in January, after only adding 74,000 jobs in December. December's weak report was attributed to bad weather affecting jobs and reporting.

We will have to wait and see what happens on Friday. Unless the January jobs report is also terrible, which seems unlikely, the basic story of the past few years remains unchanged. The economy continues to add roughly 180,000-200,000 jobs a month, which combined with baby boomers retiring is lowering the unemployment rate faster than many expected. More people with jobs and a lower unemployment rate is good for the economy. The flip side of this is that it may be bad for the market.

The Federal Reserve has been surprised by how fast unemployment has fallen. As such the Fed taper of its economic stimulus has started with unemployment near its target of below 6.5%. With the central bank purchasing fewer long-term assets each month, I expect rates to stay above last year's level and profit growth to be challenged.

Foolish takeaway
So what can an investor do in times like this? It's hard to stay sober while everyone around you is drunk on Fed-stimulus punch, telling you to join in on the fun. My advice: Keep learning, focus on your goals, have an investing plan for the long term, stick to it, and ignore the crowds.
