US stocks tend to gain around Fed's Jackson Hole summer conference, analysis shows

DataTrek Research indicates the S&P 500 historically gains an average of 0.9% in the five trading days surrounding the Federal Reserve Chair's Jackson Hole speech, with gains typically occurring post-speech as market clarity improves. While the index has uncharacteristically slipped ahead of this year's event, investors are keenly focused on Chair Powell's upcoming remarks for signals regarding a potential interest rate cut at the September FOMC meeting, with Fed Fund futures currently pricing an 84% probability.

Analysis

Historical analysis by DataTrek Research indicates a pattern of positive S&P 500 performance surrounding the Federal Reserve's Jackson Hole symposium, with an average gain of 0.9% in the ten-day period around the event since 2010. Notably, these gains have historically been concentrated in the days following the Fed Chair's speech, suggesting markets positively re-price equities based on the incremental clarity provided. However, this event carries significant two-way risk, as evidenced by the stark contrast between the 7.4% market slump after Chair Powell's hawkish 2022 speech and the 3.3% gain in 2023. This year, the index has deviated from the norm by declining pre-event, a move DataTrek suggests could precede a modest rally. Investor focus is intensely centered on Powell's upcoming speech for any signals that confirm or deny market expectations for a September interest rate cut, for which Fed Fund futures are currently pricing an 84% probability based on recent weak labor market data.

Key Decisions for Investors

• Given the historical tendency for post-speech gains but the significant downside risk highlighted by 2022's sell-off, maintaining a neutral to cautious stance on broad market indices like the S&P 500 ahead of Powell's speech is prudent.
• Investors should closely monitor Powell's commentary for any language that challenges the market's high conviction (84% probability) in a September rate cut, as any hawkish deviation would likely trigger a negative market reaction.
• Tactical traders might consider the S&P 500's current pre-speech decline as a potential short-term contrarian opportunity, as it goes against the historical pattern of stability or gains leading into the event.
