To say billionaire investor Ron Baron, who oversees some $23 billion in assets, waxed bullish on CNBC Tuesday morning would be an understatement, particularly with all the jitters and negativity swirling around the stock market lately. The 74-year-old founder of Baron Capital said that interest rates and oil prices will stay low for “a very long time,” and that the economy will grow “much faster” than it would have otherwise, bringing the market along for the ride. Hence, he sees the Dow DJIA, +0.22% potentially taking out the 40,000 level by 2030.via
