"While we expect underlying fundamentals here to remain solid, the presumption of higher rates does present a sentiment headwind," Citigroup US equity strategist Scott Chronert wrote in a new note.

Delivering his debut keynote address as Fed chair at the Jackson Hole Economic Policy Symposium on Friday, Warsh adopted a hawkish stance on interest rate policy, warning that the central bank's fight against inflation is far from over.

With inflation "running above our 2% target … the Fed's predominant focus right now should be on prices," Warsh said.

Warsh characterized recent inflation numbers as "concerning" and added that "we must be confident that underlying inflation is moving to our objective, clearly and at sufficient speed … otherwise, we have work to do."

All three major US stock indexes closed modestly lower following Warsh's comments.

Investors were hoping Warsh might hint at an upcoming interest rate cut or a softer stance on inflation. No luck.

Instead, his adamant focus on maintaining the 2% inflation target — paired with remarks implying financial conditions may not yet be restrictive enough — pushed Treasury yields higher.

Traders moved to price in a nearly 61% probability of an interest rate hike at the upcoming September FOMC meeting.

Overcoming the sentiment headwind will be key for stocks to grind higher, even with the outlook for corporate earnings staying strong. Said headwind could weigh on the valuation multiples afforded to companies as investors fret about lower future returns due to higher interest rates.

"What has transpired over the past couple of weeks involving the Federal Reserve, the Treasury Department, and the financial markets has been extremely important …and, in many ways … has reinforced concerns that we have had for some time," Miller Tabak chief strategist Matt Maley wrote in a note.

Maley added, "The stock market and the bond market have been relying on artificial stimulus and policy support for much too long. After more than 15 years of extraordinarily easy monetary policy, … quantitative easing and other forms of intervention, … the financial system appears to have reached a point where it can no longer stand entirely on its own."
