Position 2026-10-13: short (-0.30, confidence 0.55)

We hold a modest bearish lean on Bitcoin for the 13 October session, with moderate rather than high conviction. BTC closed Monday at $81,760, down 2.3% on the day and 4.7% on the week, finishing only about $100 above its session low. Two pillars carry most of the case, and both point the same way: a clear turn in institutional flows and a weak price structure. Derivatives, on-chain and macro readings add smaller confirmations. The most important change is in US spot ETF demand. October started mostly positive, but then the funds saw roughly $485M of net redemptions on 7 October and another $244M on 8 October, led by IBIT and then FBTC. The following session managed only about $21M of inflow, which left the five sessions to 9 October around $680M net negative, even though the 30-day tally is still positive at about $1.7B. Other data echo the shift. The Coinbase premium indicator has stayed negative and moved further below its weekly and monthly averages, and USDC supply shrank by about $0.8B on the week, so less fresh dollar liquidity is arriving to absorb selling. Price action confirms the flow picture. Bitcoin has given back much of its 30-day gain and sits about 35% below its all-time high. It also closed through the $81K–$83K band where most of the last day's forced liquidations printed: roughly $70M of longs versus $11M of shorts, after larger long flushes on 7–8 October. Options traders are paying more for downside protection, with put skew and the put/call ratio both above recent averages. Futures open interest is drifting lower rather than being rebuilt, and perpetual funding has cooled sharply. The market is de-risking, not buying the dip. On-chain and macro data add some weight. MVRV slipped on the week. Close to a third of supply now sits below its cost basis, and those coins may come back to market on any bounce. Active addresses are down about 20% over 30 days. The dollar is firmer over the past month, and both rate volatility and high-yield credit spreads are higher than 30 days ago. The Nasdaq softened on the week at a time when bitcoin has been tracking tech closely. The next CPI release lands on 14 October, and prediction markets put no weight on a lower policy rate at the 27–28 October FOMC. We keep the position light for good reasons. The 30-day ETF and price trends are still positive. Equity volatility is low, with the VIX near 15 and the S&P 500 near its highs. Sentiment is cooling but nowhere near capitulation, and the Kalshi ladder for Friday's close centres near $82,500, close to spot rather than well below it. Deribit options open interest is heavily concentrated at the $80,000 strike into Friday's expiry, and the CPI print could move the market either way. A recovery above the $84K area, or a return to sustained ETF inflows, would argue for moving back toward neutral.
