According to @charliebilello, the Russell 2000 Index recorded its first all-time high since November 2021 this week, highlighting a potential small-cap breakout to monitor; source: X post on Sep 21, 2025 and linked YouTube video https://www.youtube.com/watch?v=nuDXtHmKH6k&t=861s. The post explicitly raises the question of whether the small-cap breakout is underway, signaling a watchpoint for market participants; source: X post by @charliebilello on Sep 21, 2025.

According to the source, $1.6T has been added to the total crypto market cap since April, source: public X post dated Sep 21, 2025. For trading alignment, monitor BTC dominance (BTC.D) and the total market cap ex-BTC (TOTAL2) to gauge whether inflows rotate into altcoins or remain BTC-led, source: TradingView indices BTC.D and TOTAL2.

According to @MilkRoadDaily, TOTAL2—the market cap of all crypto excluding BTC—has returned to its 2021 highs, marking a pivotal resistance for altcoin season breadth, source: @MilkRoadDaily. A decisive break and sustained hold above this area would signal a broad altcoin breakout rather than a majors-only rally, source: @MilkRoadDaily. Conversely, failure to reclaim and hold would likely keep the bull market narrow and concentrated in large-cap leaders, source: @MilkRoadDaily.

According to @StockMKTNewz, the Russell 2000 posted its first record high since 2021, highlighting renewed strength in U.S. small caps as reported by CNBC (source: @StockMKTNewz on X citing CNBC).

For traders, new highs plus multi-week momentum can serve as a trend-strength and breadth signal in small caps, a cross-asset risk indicator that crypto participants may monitor for sentiment context (source: @StockMKTNewz on X citing CNBC).

According to @KobeissiLetter, NYSE and NASDAQ 52-week highs have reached their highest level of 2025, indicating improving market breadth according to @KobeissiLetter.

According to @KobeissiLetter, 60% of S&P 500 components now trade above their 200-day moving average, near the highest share since December 2024 according to @KobeissiLetter. According to @KobeissiLetter, the S&P 500 has logged 25 all-time highs year-to-date, its second-best streak since 2021, underscoring strong bullish momentum according to @KobeissiLetter.

According to @ReetikaTrades, most coins will continue to hover near all-time lows while a select few approach all-time highs due to a limited capital pool against an unlimited supply of tokens (source: @ReetikaTrades). According to @ReetikaTrades, this implies a persistently narrow market breadth where not everything can catch a bid simultaneously, concentrating performance in leaders rather than lifting laggards (source: @ReetikaTrades). According to @ReetikaTrades, traders need to adapt their playbooks—focus on leaders and avoid assuming broad beta will rescue assets stuck at ATLs—because “adapt or die” defines this regime (source: @ReetikaTrades).

According to @KobeissiLetter, the S&P 500 Information Technology sector outperformed the S&P 500 by a record 2.2x in July 2025 (source: @KobeissiLetter). The price gap between technology and the broader S&P 500 has more than doubled over the last eight years, underscoring unprecedented relative strength in mega-cap tech leadership (source: @KobeissiLetter). For trading, this level of concentration suggests index performance is highly sensitive to tech leadership, a key consideration for equity index futures, sector rotation strategies, and cross-asset risk monitoring in crypto markets (source: @KobeissiLetter).

According to The Kobeissi Letter, Nvidia NVDA now accounts for about 8 percent of the S&P 500, the highest single-stock weight since data began in 1981; Apple was the only other stock to exceed 7 percent in 2023, and no company reached this dominance during the 2000 Dot-Com Bubble, source: The Kobeissi Letter on X, Aug 9, 2025. This elevated concentration implies S&P 500 returns are increasingly driven by NVDA’s moves, a dynamic documented by S&P Dow Jones Indices analyses showing higher concentration increases single-name contribution to index performance, source: S&P Dow Jones Indices research. Traders commonly monitor market breadth and the spread between equal-weight and cap-weight S&P 500 as concentration rises to assess underlying strength, source: S&P Dow Jones Indices Indexology commentary. Crypto participants track US mega-cap tech leadership as a risk-sentiment gauge, with studies noting positive BTC to Nasdaq correlations during 2020 to 2023, source: Kaiko Research, 2023.

According to The Kobeissi Letter, despite the recent rally in the S&P 500, only 30% of stocks are currently trading above their 200-day moving average, down significantly from this year’s peak of approximately 57% in February (source: The Kobeissi Letter, April 27, 2025). This decline in market breadth suggests that the rally is being driven by a narrower selection of stocks, which may indicate potential risks for traders relying on broad market momentum. Monitoring the percentage of stocks above key moving averages remains critical for short-term trading strategies and risk management.
