The stock market is poised to surge 2% on Tuesday if new inflation data cools down as expected, JPMorgan says

• The stock market is poised to see big gains on Tuesday if the consumer price index cools down as expected.
• JPMorgan said investors could expect a 2% surge in the S&P 500 if the CPI report prints between 6.0% and 6.3%.
• "This bullish outcome would likely pull yields lower, along with the US Dollar, and boost risk assets," JPMorgan said.

The January consumer price index report is likely to jolt the stock market in a big way when it's released this Tuesday, according to a note from JPMorgan.
