The S&P 500 experienced a significant increase of 78% over the last three years, primarily fueled by investor enthusiasm for artificial intelligence (AI) technologies. However, recent volatility has caused the index to alternate between gains and losses, raising concerns among investors about the impact of geopolitical tensions and economic uncertainty on future performance.
In early 2023, the Shiller CAPE ratio of the S&P 500 peaked above 39, indicating high stock valuations not seen since the dot-com bubble burst in 2000. Historical trends suggest that peaks in this ratio have often preceded declines in the index, prompting speculation that a downturn may be imminent. Despite this risk, historical data indicates that the S&P 500 could rebound over time, endorsing a long-term investment strategy.
