What the research tells us…
The good news is that the S&P 500 has tended to perform well during the late November/early December period. The bad news is that there is no guarantee that things will follow suit in 2024. In any event, aggressive short-term traders should consider giving the bullish case the benefit of the doubt (with reasonable risk management measures in place, of course). Investors with cash to invest might consider doing so sooner rather than later, while investors looking to lighten up on their stock holdings might consider waiting a little longer.
