Stocks could slide 10% back to October lows over the next three to six months, according to Evercore's Julian Emanuel.
The Fed will keep raising interest rates, Emanuel warned, lowering the odds of a soft landing.
But that's unlikely as central bankers will keep on tightening interest rates, Emanuel said, which could mean more downside for stocks.
Fed officials raised interest rates 425 basis-points last year to tackle rising inflation, a move that caused the S&P 500 to lose 20%.
"The Fed's going to just keep going until something either softens, or invariably, as it has through most of history, breaks," Emanuel warned.
