JPMorgan's trading team said that while the risks to a strong stock market rally are growing, there is "very little chance" of a bear market downturn in the context of strong economic growth. US stocks could see a 4% -5% or even 10% correction after two consecutive years of rising more than 20% in the S & P 500, but the bull market remains intact against the backdrop of above-trend GDP, the team led by Andrew Tyler, head of global market intelligence, said in a note to clients on Monday.
