Investors are currently grappling with a significant decision as the S&P 500 recently achieved its tenth record close of the year. The dilemma lies in whether to invest in a market that may appear overextended or to hold out for a potential dip that might not materialize.
Market history, dating back to 1928, suggests that the fear surrounding buying at record highs could be overstated. The numbers reveal a striking similarity between returns following all-time highs and those after non-record days. Specifically, the median one-year gain for the S&P 500 after hitting an all-time high has been recorded at 9.6%, nearly identical to the 9.5% gain following non-record closes. Although the disparity becomes more pronounced over longer timeframes, it doesn’t seem to signal that record highs should be treated as a warning.
Analyzing the win-rate data, the findings further reinforce this narrative. The S&P 500 has been higher one year later approximately 70% of the time, regardless of whether it was closing at a record high or not. The historical context indicates that the occurrence of all-time highs should not inherently invoke alarm but rather warrant a closer examination of market dynamics.
It’s important to note that record highs often come during periods of strong momentum. The tendency of these highs to cluster suggests that investors are not necessarily buying at the peak; instead, they might be capitalizing on a market that is already on an upward trajectory.
Despite the historical data, there is an acknowledgment of the potential risks associated with all-time highs. The S&P 500 has closed at an all-time high about 6% of trading days since 1928, and that record is usually followed by some drawdowns. On average, the worst drop in the year following these highs is approximately 6%, with the most severe case leading to a 45% decline. Furthermore, there’s a historical precedent for the index to experience a drop of at least 10% within a year of hitting a new high about one-third of the time.
These insights imply that while all-time highs do not automatically signal danger, they do carry their own risks. Investors are urged to scrutinize market conditions rather than make decisions based solely on the presence of record highs. The prevailing advice emphasizes the importance of analysis over assumption in navigating these complex market landscapes.
