According to @StockMKTNewz, the U.S. stock market closed the session green today, indicating a positive finish across equities (source: @StockMKTNewz, Jan 5, 2026). The update provides no index or sector breakdown, so the only confirmed takeaway is that U.S. stocks ended higher into the close today (source: @StockMKTNewz). For trading, crypto participants can align intraday monitoring with this green close timing and check BTC and ETH behavior into the U.S. evening and Asia open, noting that the source lists no additional catalysts or data points (source: @StockMKTNewz).

According to @KobeissiLetter, U.S. stock indices opened sharply higher in early trade, with the S&P 500 back above 6,900 in an initial reaction to weekend events; source: The Kobeissi Letter on X, Jan 5, 2026. For crypto markets, equity risk-on episodes have historically aligned with higher short-term beta in BTC and ETH when cross-asset correlations rise; source: International Monetary Fund, Crypto Prices Move More in Sync With Stock Markets (Oct 2022). Equity surges are typically associated with lower implied volatility (VIX), a dynamic that can ease cross-asset risk premia and support liquidity conditions; source: Cboe Global Markets, VIX methodology and historical relationship notes.

According to Charlie Bilello, the S&P 500 (SPX) was down over 15% year-to-date on April 8 last year, then rallied roughly 37% to finish the year up over 17% while recording 39 all-time highs, which he describes as one of the greatest market comebacks in history (source: Charlie Bilello). According to IMF research, stock–crypto correlations strengthened after 2020, so equity rebounds of this magnitude often coincide with improved risk appetite in BTC and ETH, making SPX trend a key macro signal for crypto traders (source: IMF).

According to @charliebilello, since 1928 the S&P 500 has delivered roughly 10% average annual returns while enduring an average intra-year drawdown of about -16%, underscoring that long-term upside has historically come with sizable pullbacks; source: @charliebilello on X and bilello.blog/newsletter. Traders can frame SPX risk budgets around the historical -16% intra-year drawdown profile when assessing position sizing and stop distances during uptrends; source: @charliebilello on X and bilello.blog/newsletter. Because Bitcoin’s correlation with U.S. equities rose markedly after 2020, equity drawdowns have increasingly coincided with downside in BTC and ETH, making SPX weakness a relevant risk signal for crypto leverage and hedging; source: International Monetary Fund, Crypto Prices Move More in Sync with Equities, Jan 2022.

According to @CNBC, the outlet published a new screen of the most overbought and oversold S&P 500 stocks as 2026 begins, giving traders a timely list to identify potential mean-reversion or momentum opportunities; source: CNBC, Jan 3, 2026. Traders typically use overbought/oversold readings as timing inputs alongside risk management because extremes can persist in strong trends, with RSI 70/30 levels widely referenced for entries and exits; source: Investopedia, Relative Strength Index (RSI), accessed Jan 2026. Given documented periods of elevated correlation between U.S. equities and crypto, S&P 500 risk-on/off swings are relevant for BTC and ETH positioning and model inputs; source: International Monetary Fund (IMF), Global Financial Stability Note on crypto–equity correlations, 2022.

According to @charliebilello, $1 invested in the S&P 500 in 1964 would be $455 today, while $1 invested in Berkshire Hathaway would be $60,883, underscoring Berkshire’s multi-decade outperformance versus the index for long-horizon investors, source: Charlie Bilello on X, Jan 2, 2026; Video: youtube.com/watch?v=RVigGUYFU64.

According to @StockMKTNewz, the NASDAQ 100 and S&P 500 flipped from green to red intraday while the Dow Jones turned from red to green, signaling a real-time divergence between growth and blue-chip benchmarks (source: @StockMKTNewz on X, Jan 2, 2026). For trading, this divergence favors relative-strength rotation setups—hedge or underweight QQQ versus the stronger DIA and tighten stops on high-beta tech until breadth improves (source: @StockMKTNewz on X, Jan 2, 2026). Crypto traders can use the reported equity flip as a real-time risk gauge when managing BTC and ETH exposure during U.S. hours (source: @StockMKTNewz on X, Jan 2, 2026).

According to @charliebilello, the S&P 500 has outperformed the S&P 500 Equal Weight Index by 34% over the past three years, the widest three-year performance gap in history, surpassing the prior 32% record from 1997 to 1999, source: @charliebilello. According to @charliebilello, the 1997 to 1999 episode was followed by a sharp reversal and seven years of Equal Weight outperformance, underscoring elevated concentration risk when cap-weight leadership becomes extreme, source: @charliebilello. According to @charliebilello, traders should note that this update is about equity market breadth and dispersion; no crypto-specific impacts were provided by the source, source: @charliebilello.

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).

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).
