Oil prices are on the rise again.  On Tuesday, the price per barrel neared $82 after surging stock markets and a weak dollar helped boost crude to a three-month high.

"Traders and investors continue to like buying oil, for reasons that are not immediately or readily apparent to those steeped in fundamental knowledge," Cameron Hanover Energy Research said in a note to investors.

Analysts say that if the price of oil remains above $80, it will lead to higher prices at the pump - especially during the summer when demand is the highest.  Currently, the national average for gasoline is $2.74, 20 cents higher than a year ago.

The high for oil prices this year is $87 per barrel.
     
Meanwhile, crude isn't the only thing going up. After a recent correction, the Dow Jones industrial average is now up slightly for the year.
    
Analysts say investors are expecting the economy to keep growing - even if it's only at a slow pace.
