The altcoin season index hit a one-year high, with 20 of 26 categories declining. The index measures how many coins have outperformed Bitcoin over the past 90 days, not how many sectors are rising. This week, these two things moved in opposite directions. CoinMarketCap Bitcoin Cross-chain Ethereum · 2026-10-13 08:49

🦊 Nova's Take The altcoin season index just hit a one-year high, yet 20 of 26 sectors actually declined — a classic divergence signal. The index only counts how many coins beat BTC over 90 days, so a few large-cap alts (ETH, cross-chain names) are dragging the average up while the broad market bleeds. 📊 Market Impact Short-term, this points to narrowing breadth — capital is rotating into a handful of leaders rather than fueling a true altseason. Mid-term, if BTC dominance stays firm, weak sectors likely keep bleeding while index readings stay misleadingly "bullish." 💡 Trading Advice Favor BTC and top-tier alts (ETH, major cross-chain tokens) over scattered small-caps, and treat the high index print as a trap rather than a green light. Keep position sizes modest and stops tight — breadth divergence often precedes a sharper correction. *Not financial advice — manage your own risk.* 🎯
