The S&P 500 is coming off one of its strongest runs in years. The index enjoyed an eight-day winning streak earlier this month that saw it close above 1,500 for the first time since 2007. And the S&P isn't alone. All three major indices have come out swinging in 2013, with each up several percentage points since the start of the year. 

But before you pop the champagne and declare 2013 the Year of the Booming Economy, take a breath. Beyond the stock market, the wider U.S. economy still has a whole bunch of problems.

Sure, rising earnings at publicly listed companies such as Proctor & Gamble and Starbucks have led to strong returns for some investors. But most of the gains on Wall Street are far removed from the economic woes that continue to drag down the overall economy, namely the slow-growth environment that is not expected to go away anytime soon. Indeed, America's GDP contracted in the fourth quarter of 2012.

Meanwhile, consumer spending — which accounts for roughly two-thirds of U.S. economic activity — is likely to take a small hit from a 2 percent payroll tax increase that took effect on Jan. 1. The tax hike came as a result of the fiscal cliff agreement, which did not renew a temporary payroll tax reduction, returning the rate from 4.2 percent to 6.2 percent. If you haven't noticed that on your paycheck yet, you will soon.

Though unemployment has fallen to 7.8 percent, its lowest level in four years, Friday's labor report is not expected to deliver any meaningful improvement for those who have been jobless for more than 27 weeks, a group that makes up nearly 40 percent of unemployed Americans. 

Of course, it's not all bad. The manufacturing sector just recorded its fastest growth rate since March 2011, thanks to a rise in domestic demand. The U.S. housing market has also witnessed a slight resurgence, although many experts are not predicting any sea change in home prices during the next five years. And as Briklin Dwyer, an economist at BNP Paribas tells Reuters, both manufacturing and housing "need to show bigger improvement for quite some time to affect the broader economy." 

Undoubtedly, the booming stock market is not a bad thing — and it'll surely line the pockets of many, many investors. But we should all be wary of reading too much into it. For most Americans, the stock market and the economy are two very different things.
