Call it the long holiday weekend hangover: U.S. stocks were mostly falling Tuesday -- retreating from their August gains, though still hovering near record highs.

Remember, September is historically a down month for investors.

The S&P 500 managed to hold onto the 2,000 level, but still finished in the red. Crude suffered its steepest selloff in almost two years, dragging down energy names such as Chevron (CVX) & Exxon Mobil (XOM), which together shaved off a combined 23 points from the DJIA.  

Investors are waiting for the big-ticket August jobs report -- due to be released Friday. The question remains whether we could see another robust month, with jobs gains north of 200,000.

In an exclusive interview with FOX Business, economic heavyweight and former Chairman of the Council of Economic Advisors Austan Goolsbee shared what he considers to be the most important data point to watch in that jobs report, which is important for your money, so you don't want to miss it.

And today's celebrity forecast  -- cloudy with a chance of picture-storms. Some of Hollywood's biggest names,  including Oscar-winning actress Jennifer Lawrence and super-model Kate Upton, are doing damage control after hackers accessed more than 100 personal photos through their i-Cloud accounts.

So as users and corporations search for safety, who could be the biggest beneficiary of Apple's security breach?

One tech name popping back on the radar is BlackBerry, which still has one of the best enterprise security systems out there.

Head to FOXBusiness.com/oncall to check out my interview with an all-star tech panel -- to find out why some think Apple should consider buying BlackBerry.

Let's take a look at both stocks -- BlackBerry popping today -- closing the day with a 2.6% gain while Apple investors seemed unfazed by the news, taking Apple to a new 52-week high of $103.74 -- and ending the day with a slight gain. All that ahead of Apple's big product announcement next week.  

Now, here is what's coming up tomorrow: Auto makers will be reporting new car sales numbers for the month of August. And former Chrysler motors CEO Bob Nardelli will be joining me for a FOX Business exclusive with his reaction to the numbers.
