Bitcoin's role in the portfolio
Bitcoin prices fell below the US$77,000 mark and hovered around US$76,725 during Sunday trading hours. The market sentiment indicator soared to 89, the highest level since March 2024, before falling back.
The U.S. spot Bitcoin ETF recorded a total net outflow of US$462.7 million between September 8 and 11. Bitcoin Suisse believes that moderate Bitcoin exposure can help improve the performance of traditional investment portfolios.
The latest U.S. inflation data for August showed that the annual price increase was 3.4%, and monetary policy faced continued tensions.
Market Dynamics and Sentiment Analysis
Bitcoin fell below the US$77,000 mark in Sunday trading and closed at approximately US$76,725, a drop of 0.80%. The cryptocurrency closed close close to $77,300 on Saturday, but fell further in early Sunday.
As bond yields rise and expectations that high interest rates will continue, the attractiveness of dollar-denominated assets has increased. This development has put downward pressure on Bitcoin and the broader cryptocurrency ecosystem.
CryptoQuant analyst Darkfost observed that Bitcoin's market sentiment measure temporarily exceeded 89 points on a 100-point scale, reaching what it calls "extreme greed" level. This is the highest value recorded since March 2024. Such strong market sentiment came in March 2024, when Bitcoin's rise triggered the strongest investor enthusiasm in the past two years.
Although Bitcoin is trying to maintain its current valuation, Darkfost pointed out that sentiment indicators have fallen back from their peaks. He emphasized that extreme sentiment measures-whether bullish or bearish-often appear near potential market turning points, but he did not provide specific price forecasts.
For reference, Alternative.me's independently released Fear and Greed Index recorded 63 points during the reporting period, classifying it as "Greed." The index takes into account factors such as volatility, transaction volume, social media engagement and online search patterns.
ETF outflows accelerate
According to data from Farside Analytics, U.S. spot bitcoin exchange-traded funds (ETFs) recorded a total outflow of US$462.7 million during the trading period from September 8 to 11. During this period, negative net flow was observed on each trading day.
Thursday became the most significant day for single-day outflows, with redemptions reaching $282.7 million. ARK21 Shares 'ARBK product experienced the steepest single fund decline, with weekly outflows of $234.2 million, while BlackRock's IBIT product posted outflows of $52.5 million over four days.
Market analyst Ted Pillows expressed concern about this week's chart shape, pointing out that Bitcoin's "weekly K-line looks very bad" and warning that "if we close in this format, sellers will take control of the situation." His assessment reflects the general caution among market participants as the weekend approaches.
Bitcoin's Role in Portfolio
Swiss Bank released the "2026 Crypto Wealth Management Report", arguing that Bitcoin can bring significant benefits to traditional investment strategies. Given that artificial intelligence investment has led to concentration of positions held by a few technology giants, and that U.S. federal debt has exceeded US$40 trillion, the organization believes that fixed-income securities no longer have their historical risk-spreading advantages.
Its analytical framework shows that funding 1% of Bitcoin positions by reducing bond allocation can increase annualized portfolio returns from 6.2% to 7.2%. If this allocation is expanded to 2.5%, the return will rise to 8.6%.
It is expected that the leading U.S. hyperscale infrastructure providers will invest more than $800 billion in artificial intelligence initiatives in 2026 and more than $1 trillion in 2027.
U.S. inflation indicators showed that consumer prices rose 3.4% in the twelve months to August, unchanged from July data. The Federal Reserve will hold its next monetary policy meeting from September 15 to 16.
During Sunday's 24-hour trading session, Bitcoin's trading range is approximately US$76,393 to US$79,607, and the price is currently at the lower end of this range.
