According to @charliebilello, the S&P 500 registered 39 additional all-time highs in 2025, confirming persistent strength in US large-cap equities (source: Charlie Bilello on X, Dec 31, 2025). For trading, clusters of new highs typically align with momentum and positive return autocorrelation that trend-following strategies seek to exploit (sources: Jegadeesh and Titman 1993; Moskowitz, Ooi, and Pedersen 2012). Since 2020, crypto assets have shown higher co-movement with US equities, meaning sustained SPX risk-on regimes can coincide with tailwinds for BTC and ETH beta exposure (sources: IMF research by Adrian, Iyer, and Qureshi 2022; BIS Quarterly Review 2022). Traders can watch volatility compression and breadth as confirmation, such as VIX levels for risk appetite and the prevalence of 52-week highs as a breadth signal, and then check BTC–equity rolling correlations for potential spillover (sources: Cboe VIX methodology; George and Hwang 2004 on 52-week-high momentum; IMF 2022 on rising crypto–equity correlations).

According to the source, BTC has declined about 20% since early November, while gold gained roughly 9% and the S&P 500 added around 1% over the same period. According to the source citing market intelligence firm Santiment, 2026 will offer opportunities for crypto to catch up following this relative underperformance.

According to @charliebilello on X on Dec 31, 2025, five of the Magnificent Seven underperformed the S&P 500 in 2025, with only Google and Nvidia outperforming; the source notes this is a very different picture than 2023/2024. Based on the same source’s performance comparison, relative strength in 2025 was concentrated in GOOGL and NVDA versus the index.

According to Charlie Bilello, the S&P 500 (SPX) ended 2025 up nearly 18%, exceeding broad expectations and offering a strong risk backdrop that many crypto traders track as a macro signal for cross-asset sentiment (source: Charlie Bilello on X, Dec 31, 2025; bilello.blog/newsletter).

According to @StockMKTNewz, the NASDAQ 100 (QQQ) finished 2025 up by more than 20% for the third consecutive year (source: @StockMKTNewz). According to @StockMKTNewz, the S&P 500 (SPY) and the Dow Jones both closed 2025 up by more than 10% for the third straight year (source: @StockMKTNewz). According to @StockMKTNewz, these multi-year gains confirm sustained index strength that traders can reference as a momentum benchmark when calibrating exposure in QQQ and SPY at the start of 2026 (source: @StockMKTNewz).

According to CNBC, the S&P 500 is on a rare streak of high returns, prompting a look at what historical patterns may imply for 2026; source: CNBC. Historical data show that U.S. midterm election years have typically been the weakest of the four-year presidential cycle for the S&P 500, with elevated volatility and rebounds often concentrated later in the year, based on Stock Trader’s Almanac data summarized by Fidelity Investments; source: Fidelity Investments. Research from the International Monetary Fund finds that crypto assets have moved more in sync with U.S. equities since 2020 (the BTC–S&P 500 return correlation rose to roughly 0.36 in 2020–2021 from near zero pre-pandemic), indicating that shifts in the S&P 500 trend in 2026 can materially influence BTC and ETH performance; source: International Monetary Fund.

According to @StockMKTNewz, the U.S. stock market opened the final trading day of the year in the red, signaling a risk-off start to December 31, 2025 (Source: @StockMKTNewz on X, Dec 31, 2025). Research shows Bitcoin and U.S. equities have exhibited stronger return correlations since 2020, increasing the likelihood of cross-asset moves when stocks weaken (Source: IMF, Crypto Prices Move with Equity Markets, 2022; BIS, Quarterly Review analysis on crypto–macro linkages, 2022). Crypto traders should monitor BTC and ETH price action around the U.S. cash session for potential spillovers consistent with these documented correlations (Source: IMF 2022; BIS 2022).

According to @StockMKTNewz, the U.S. stock market opened the December 29, 2025 session in the red. According to @StockMKTNewz, the update did not include index-level or sector specifics beyond noting a red open.

According to @KobeissiLetter, the 2025 view is to own assets or be left behind, with just about all assets pushing higher this year (source: @KobeissiLetter). According to @KobeissiLetter, gold and silver have recently led performance, rising 4 and 8 times as much as the S&P 500 year-to-date, signaling strong relative momentum in precious metals versus equities (source: @KobeissiLetter). According to @KobeissiLetter, the move started with a weaker US Dollar, identifying USD weakness as the catalyst behind the broad asset advance (source: @KobeissiLetter).

According to @CNBC, a fresh screen highlights the most overbought S&P 500 stocks as 2026 approaches, indicating stretched momentum conditions into year-end. According to the CFA Institute, overbought is commonly defined using momentum oscillators such as the Relative Strength Index (RSI) above 70, a level traders use to gauge mean-reversion risk and adjust risk management. According to Investopedia, a widely watched trigger is when RSI falls back below 70 after an overbought reading, which many traders use to time profit-taking or initiate hedges. According to the IMF, U.S. equities and Bitcoin have exhibited periods of positive return correlation since 2020, so reversals in overbought equity leaders can coincide with volatility in BTC and ETH during such regimes. According to Cboe, the VIX reflects the S&P 500’s 30-day implied volatility, and a rising VIX alongside overbought conditions is monitored as a near-term drawdown risk signal across risk assets.

According to @QCompounding, buying the S&P 500 at a 5.3x P/E in 1917 and selling at 34x in 1999 would have delivered an 11.6% annualized return, with only 2.3% per year coming from P/E multiple expansion, citing Terry Smith; source: @QCompounding. For traders, this decomposition indicates that most of the long-run return in that period came from earnings growth and reinvestment rather than valuation rerating, making fundamentals the primary driver of performance; source: @QCompounding. Positioning takeaway: prioritize earnings durability, reinvestment rate, and cash-return policies over hopes for late-cycle multiple expansion when sizing equity or index exposure; source: @QCompounding. For crypto-adjacent equities and tokenized equity products, the same finding cautions against relying solely on rerating without cash-flow support, highlighting the importance of fundamentals-based frameworks even in risk assets; source: @QCompounding.

According to @StockMKTNewz, today would be the second session of the seven-trading-day Santa Rally window in U.S. equities (Source: @StockMKTNewz). The Santa Rally is defined as the last five trading days of December and the first two of January, and the S&P 500 has averaged roughly a 1.3% gain over this span since 1950 (Source: Stock Trader's Almanac, Yale Hirsch). Hirsch also notes the historical adage that when the Santa Rally fails, it can foreshadow weaker near-term equity performance (Source: Stock Trader's Almanac). Crypto has exhibited higher co-movement with U.S. equities in recent years, linking equity risk sentiment to BTC and ETH performance during such seasonal windows (Source: International Monetary Fund research).

According to The Kobeissi Letter, the Magnificent 7 are up 27% year-to-date and on track for a third consecutive annual gain after rallies of 107% in 2023 and 67% in 2024 (source: The Kobeissi Letter). The Kobeissi Letter reports the group is up 338% since the start of 2023 and accounted for 45% of the S&P 500’s 18% total return this year (source: The Kobeissi Letter). Based on The Kobeissi Letter’s data that the cohort’s market cap is $21 trillion, or 34% of the index, a 1% move in the group would mechanically contribute about 0.34% to the headline index, all else equal (source: The Kobeissi Letter). For crypto positioning, The Kobeissi Letter’s figures highlight extreme U.S. equity leadership that traders can use as macro risk context when assessing BTC and ETH exposure (source: The Kobeissi Letter).
