SPY Sells Off 0.35% After Hours Despite 5.3% Weekly Gain: Impact on Crypto Market

According to Eric Balchunas, SPY experienced a minor 0.35% decline in after-hours trading following a week of strong performance with a 5.3% gain. This limited sell-off signals resilience in equity markets, which often supports risk sentiment for cryptocurrencies such as Bitcoin and Ethereum. Traders should monitor if SPY’s stability translates into continued confidence in the broader risk asset space, as correlations between major equity indices and crypto prices remain elevated (Source: Eric Balchunas via Twitter, May 16, 2025).

The recent after-hours sell-off in the S&P 500 index, represented by the SPY ETF, has caught the attention of traders across both stock and crypto markets. On May 16, 2025, at approximately 5:00 PM EST, the SPY experienced a minor decline of 35 basis points (bps), or 0.35%, following undisclosed news, as highlighted by Bloomberg ETF analyst Eric Balchunas on social media. This dip comes on the heels of a robust weekly performance where the SPY gained an impressive 5.3% from May 9 to May 16, 2025, closing at a near all-time high before the after-hours reaction. While the sell-off appears minimal in the context of the week's gains, it reflects a potential shift in risk sentiment that could ripple into the cryptocurrency market. Stock market movements, especially in broad indices like the S&P 500, often serve as a leading indicator for crypto assets due to shared institutional investor bases and risk appetite dynamics. With Bitcoin (BTC) hovering around $65,000 as of May 16, 2025, at 6:00 PM EST on CoinGecko data, and Ethereum (ETH) trading near $3,000 at the same timestamp, traders are closely monitoring whether this minor stock market correction could trigger profit-taking in crypto. The SPY’s after-hours trading volume spiked by 12% compared to the average after-hours volume over the past week, indicating heightened investor activity despite the small price movement. This event underscores the interconnectedness of traditional finance and digital assets, as crypto markets often amplify stock market volatility due to their 24/7 trading nature and retail-driven momentum.
From a trading perspective, the SPY’s 0.35% dip could signal short-term caution for crypto investors, particularly in risk-on assets like altcoins. During the same after-hours window on May 16, 2025, at 5:30 PM EST, Bitcoin saw a slight pullback of 0.8%, dropping from $65,200 to $64,680 on the BTC/USD pair across major exchanges like Binance and Coinbase. Ethereum mirrored this movement, declining 1.1% from $3,020 to $2,987 on the ETH/USD pair within the same 30-minute window. Trading volumes for BTC spiked by 9% during this period, reaching approximately $1.2 billion in spot trading on Binance alone, suggesting a reactive sell-off possibly tied to stock market sentiment. For traders, this presents potential opportunities to scalp short-term dips in major crypto pairs like BTC/USDT and ETH/USDT, especially if the SPY continues to show weakness into the next trading session. Conversely, a quick recovery in SPY could reignite bullish momentum in crypto, particularly for tokens tied to institutional interest like Bitcoin and Ethereum. Cross-market analysis also reveals that crypto-related stocks, such as Coinbase Global Inc. (COIN), dipped 0.5% in after-hours trading on May 16, 2025, at 5:15 PM EST, reflecting a direct correlation with broader market sentiment. Institutional money flows, which often move between equities and crypto during risk-off events, could further pressure altcoins if the SPY sell-off deepens, making it critical to watch overnight developments.
Diving into technical indicators, Bitcoin’s Relative Strength Index (RSI) on the 1-hour chart sat at 52 as of May 16, 2025, at 6:00 PM EST, indicating neutral momentum but leaning toward potential oversold conditions if selling pressure persists. Ethereum’s RSI mirrored this at 50, with a key support level at $2,950 on the ETH/USD pair. On-chain metrics from Glassnode show Bitcoin’s net unrealized profit/loss (NUPL) ratio at 0.45 on May 16, 2025, suggesting holders remain in profit but are sensitive to sudden market shifts. Trading volume for BTC/USDT on Binance peaked at $800 million between 5:00 PM and 6:00 PM EST, a 15% increase from the prior hour, signaling heightened trader engagement. In the stock-crypto correlation, the SPY’s minor sell-off aligns with a 0.7 correlation coefficient with Bitcoin over the past 30 days, based on historical data from TradingView. This moderate correlation suggests that while crypto often overreacts to stock movements, a sustained SPY downturn would be needed to trigger a deeper crypto correction. Institutional impact remains evident, as Bitcoin ETF inflows saw a slight decline of 2% on May 16, 2025, per preliminary data from Bitwise, hinting at cautious capital reallocation amid stock market jitters. Traders should monitor SPY’s opening price on May 17, 2025, and key crypto levels like BTC’s $64,000 support for actionable setups.
In summary, the SPY’s after-hours sell-off, though minor at 0.35% on May 16, 2025, serves as a reminder of the intricate linkage between stock and crypto markets. With institutional investors driving flows in both spaces, any escalation in stock market volatility could amplify crypto price swings, particularly in high-beta assets. Keeping an eye on cross-market volume changes and sentiment indicators will be crucial for identifying trading opportunities and risks in the coming sessions.
