Seeing the S&P 500 $S&P 500(.SPX)$  $SPDR S&P 500 ETF Trust(SPY)$   notch its 39th record high around 6,927 reinforces how powerful year-end seasonality can be, especially when liquidity improves and positioning turns more supportive. Historically, the Santa rally isn't just a festive myth — it reflects tax-loss selling ending, performance chasing by funds, and generally lighter risk aversion into year-end. That backdrop helps explain why markets can keep grinding higher even when valuations already look stretched.

Whether the Santa rally extends into January, in my view, depends less on sentiment and more on positioning and liquidity. If investors head into year-end underinvested or still hedged, January can see follow-through buying as portfolios reset and new allocations come in. However, January is also when reality checks tend to appear — earnings guidance, macro data, and policy expectations can quickly override seasonal optimism.

On the question of going long purely for calendar effects, I'm cautious. I don't like being long just because "it's supposed to go up." Calendar effects work best when they align with trend and structure, not when they are traded blindly. At current highs, risk-reward matters more than being right about direction.

That said, if the market structure remains supportive — strong breadth, contained volatility, and no sudden tightening in financial conditions — I'm comfortable staying long selectively rather than aggressively adding. I'd rather express a bullish bias through defined-risk structures or partial exposure instead of outright chasing index highs.

So for me, the Santa rally is a tailwind, not a strategy by itself. I respect the seasonality, but I anchor decisions on liquidity, positioning, and risk management. If January brings follow-through, I'll stay with the trend; if not, I'm prepared to step aside without forcing a trade.

As a retail investor, I focus mainly on the US and Singapore markets, combining a mix of technical trading and long-term investing strategies. I enjoy analyzing charts, spotting patterns, and making calculated moves based on both market sentiment and fundamentals. While I'm not a professional, I treat my portfolio seriously and continue to learn and grow with each trade.
