(Bloomberg) -- While much of Wall Street is standing by to hear what Federal Reserve Chairman Kevin Warsh has to say today at his first speech to the Jackson Hole economic symposium, history suggests the stock market is likely to react with a whimper rather than a roar.

Despite a few exceptions, a Fed chair's speech at the symposium normally isn't a big catalyst for stocks — unless it comes before a crucial shift in monetary policy. Since 2000, the S&P 500 Index has gained just 0.4% on average in the week following the gathering, data compiled by Bloomberg show. And options markets aren't pricing in any fireworks this time either.

Of course, "this time won't be different" are arguably the second-most dangerous words on Wall Street after "this time it's different." As a result, many traders will be ready to take action, especially since Warsh has broken with his predecessors by abstaining from providing guidance on how the central bank is thinking about potential future interest rates moves.

"The bar is low, with traders not anticipating any groundbreaking changes to his policy views," Kevin Flanagan, head of investment and fixed income strategy at WisdomTree, said by phone. "But a lack of forward guidance still leaves the market up to its own devices to interpret what he says, which leaves the risk of misinterpretation across Wall Street."

Warsh, scheduled to speak Friday at 10 a.m. New York Time, could remain especially tight-lipped about the timing of hikes since the next jobs report on Sept. 4 and consumer price figures on Sept. 11 are both likely to be important data points for the Fed when they meet later in the month to set rates.

Warsh "is likely to acknowledge the better recent inflation news but is unlikely to provide policy guidance," Goldman Sachs Group Inc. economists led by Jan Hatzius wrote in a note to clients on Tuesday, adding that they expect the Fed to keep rates steady in September and through the year-end. "The majority of participants and especially the majority of voters will feel even more strongly that it is appropriate to remain on hold after better inflation reports in June and July."

Any surprises, though, could trigger some volatility since swaps traders are pricing in only about a one-in-three chance that the Fed will raise borrowing costs in September.

"His first Jackson Hole speech could be a learning curve," Flanagan said. "Here's what we all want to know: How does he view the economy and inflation right now and in the future?"

In the options market, traders are pricing in a one-day swing of only 0.6% in either direction for the S&P 500, according to Piper Sandler's Daniel Kirsch, head of options for the brokerage.

Yet while history suggests Jackson Hole-induced market jolts are rare, they're not unheard of.

In 2022, former Fed Chair Jerome Powell surprised the market by delivering a hawkish speech from Wyoming, warning investors that fighting inflation would bring "pain" to households and businesses. The S&P 500 tumbled 3.4% that day, while 10-year yields notched an 8-basis-point intraday swing. The selloffs continued in subsequent weeks as traders boosted expectations for more rate hikes.

This is the risk confronting money managers who've plunged back into Big Tech stocks in droves, chasing the S&P 500 ever higher after a nearly $12 trillion rebound following the global growth scare earlier in the year with the onset of the Iran war.

For now, volatility appears to be fading, with the Cboe Volatility Index, or VIX, trading below 15 — roughly 20% below its one-year average. The S&P 500 has been remarkably calm, going 21 straight sessions without a decline of at least 1%, according to data compiled by Bloomberg. The benchmark index remains less than 1% from its last record high.

That a firm sign the market has grown comfortable that the risk from Jackson Hole is receding, with investors no longer expecting aggressive rate hikes that historically have been used to cool runaway inflation.

"Warsh's big push is to not make forward-looking comments on monetary policy, so he probably won't really go there," said Jed Ellerbroek, portfolio manager at Argent Capital Management in St. Louis. "Tariff impacts on inflation are waning. The Middle East conflict with oil prices is volatile and unpredictable, but there's some relief. That means his comments at Jackson Hole will likely only be minimally useful for traders."
