Introduction

The Federal Reserve's upcoming rate decision has investors scanning history for clues. How have stocks actually performed in the days and weeks following past meetings? New data offers a clearer picture of what to expect, whether the Fed lifts rates or holds steady.

What Happened

Fed meeting days often mirror a typical trading session, but the days that follow tell a different story. In the week after a meeting, the S&P 500 has historically underperformed, averaging barely a breakeven return with roughly half the days in the green. Typically, the index posts a 0.25% daily gain with 61% of days positive—meeting days tend to lag that benchmark. When the Fed chooses to raise rates, the week that follows averages a 0.54% decline, and only 40% of those weeks finish positive. Holding rates steady paints a brighter picture: the post-meeting week averages a 0.23% gain, with over half the days posting gains. Even the day of the decision is revealing: rate-hike days see the index rise just 35% of the time, yet when it does climb, the average jump hits 1.8%, pulling the overall day's average to a modest 0.10% gain.

Why This Matters

For anyone tracking the market, knowing the typical post-Fed pattern helps frame expectations ahead of the next announcement. A rate hike historically weighs on the index in the short term, while a hold usually delivers a modest rebound. Beyond the decision itself, broader sentiment plays a role. Investor mood, as measured by the AAII sentiment poll, can signal how long the aftereffects last. When bearish sentiment precedes the meeting, recoveries tend to happen faster, even after a rate increase. This means the story doesn't end with the Fed's choice—what investors were thinking in the weeks prior often dictates the next move.

Key Takeaways

  • Fed meeting days rarely outperform a standard session; the real action happens in the days after.
  • A rate hike in the week following typically results in a small decline, while holding rates steady usually brings a modest gain.
  • The day-of reaction to a hike is mixed, but strong upside moves when stocks rise keep the average from falling further.
  • AAII sentiment ahead of the meeting adds a predictive layer: bearish readings before the Fed often lead to quicker rebounds, regardless of the decision.
  • Looking two weeks out, both paths converge around a 0.75% gain, but the steady-rate scenario remains the more reliable route.

Conclusion

The Fed's next move will spark immediate market reaction, but the longer-term pattern is what truly matters for positioning. Rate hikes tend to pressure stocks in the week after, while holding steady offers a more favorable short-term outlook. Investor sentiment, particularly from the AAII poll, can tip the timing of the recovery. For traders and long-term investors alike, the takeaway is clear: the decision is just the starting point, and what comes next often depends on the broader mood in the market.
