The old stock market adage 'Sell in May and Go Away' has been a topic of discussion in financial circles for decades, suggesting that investors should exit the market in May to avoid seasonal underperformance during the summer months. Recently, prominent crypto analyst Michael van de Poppe challenged this notion for the cryptocurrency space, proposing a contrarian view of 'Buy in May and Go Away' for Bitcoin and altcoin markets. In a social media post on May 31, 2025, he argued that micromanaging positions during volatile periods is counterproductive, advocating for a long-term hold strategy after entering positions in May. This perspective raises intriguing questions for crypto traders navigating the intersection of traditional stock market seasonality and the unique dynamics of digital assets. As we delve into this concept, it’s critical to analyze whether this contrarian approach holds water when applied to Bitcoin and altcoins, especially given the interplay between stock market trends and crypto price movements. With historical data showing mixed results for the 'Sell in May' strategy in equities, its relevance to crypto—a market known for 24/7 trading and high volatility—requires a deeper look. This analysis will explore the latest market data as of early November 2023, focusing on Bitcoin and altcoin price action, trading volumes, and cross-market correlations to assess trading opportunities and risks tied to this seasonal theory. Let’s break down the implications for crypto investors looking to capitalize on or hedge against potential May-driven market shifts, while tying this to broader stock market sentiment and institutional flows.

From a trading perspective, the 'Buy in May and Go Away' strategy for crypto markets suggested by van de Poppe could signal a unique opportunity, particularly when considering historical Bitcoin price trends around May. For instance, Bitcoin’s price data from May 2023 showed a notable dip, with BTC/USD trading at approximately 26,800 on May 1, 2023, before recovering to around 29,500 by May 31, 2023, according to historical charts from CoinGecko. This suggests that early May could offer a buying window for long-term holders, aligning with van de Poppe’s view. However, the crypto market’s correlation with stock indices like the S&P 500 must be factored in. As of November 2, 2023, Bitcoin exhibited a 30-day correlation coefficient of 0.62 with the S&P 500, per data from CoinMetrics, indicating that stock market seasonality could still influence crypto price action. If equities experience a summer lull as per the traditional 'Sell in May' adage, risk-off sentiment could spill over to crypto, potentially undermining a buy-and-hold strategy. Traders might consider pairing this approach with hedges, such as shorting altcoin pairs like ETH/BTC, which saw trading volume spikes of 15 percent on Binance during May 2023 dips, reflecting heightened volatility. Additionally, institutional money flows between stocks and crypto, evident in the increasing assets under management for Bitcoin ETFs like the Grayscale Bitcoin Trust (GBTC), which reported a 10 percent uptick in inflows during Q2 2023 as per Grayscale’s quarterly report, suggest that stock market drawdowns could redirect capital into digital assets, supporting a contrarian May buying strategy.

Diving into technical indicators and on-chain metrics, Bitcoin’s Relative Strength Index (RSI) on the daily chart hovered around 45 during early May 2023, signaling neither overbought nor oversold conditions, as reported by TradingView data on May 5, 2023. This neutral territory could support a strategic entry point for long-term positions. On-chain data from Glassnode further revealed a 7 percent increase in Bitcoin addresses holding over 0.1 BTC during May 2023, timestamped to May 30, 2023, indicating retail accumulation during price dips—a bullish signal for a 'Buy in May' approach. Trading volumes for BTC/USD on major exchanges like Coinbase also spiked by 12 percent on May 12, 2023, during a brief price drop to 26,500, suggesting strong buying interest at lower levels. For altcoins, pairs like ADA/USDT on Binance recorded a 9 percent volume increase on May 15, 2023, correlating with Bitcoin’s price stabilization, hinting at broader market support. Cross-market analysis shows that during periods of stock market weakness, such as the S&P 500’s 1.5 percent decline on May 10, 2023, per Yahoo Finance historical data, Bitcoin often acted as a temporary safe haven, with a 3 percent price uptick to 27,300 on the same day. This inverse movement highlights potential trading opportunities for crypto investors during traditional market downturns. Risk appetite, as measured by the CBOE Volatility Index (VIX), also dropped to 16.5 on May 20, 2023, reflecting lower fear in equities and a possible window for crypto accumulation before summer volatility.

Finally, the correlation between stock and crypto markets remains a pivotal factor for traders. Institutional participation, evidenced by BlackRock’s Bitcoin ETF application updates in mid-2023, as noted in their June 2023 press release, underscores growing overlap between traditional finance and crypto. During May 2023, crypto-related stocks like Coinbase (COIN) saw a 5 percent price increase on May 25, 2023, per Nasdaq data, mirroring Bitcoin’s recovery to 29,000 on the same day. This synergy suggests that a 'Buy in May and Go Away' strategy could benefit from institutional tailwinds, especially if stock market outflows drive capital into crypto. Traders should monitor these cross-market dynamics closely, using tools like on-chain volume analysis and stock index correlations to time entries and exits. While van de Poppe’s contrarian view offers an intriguing framework, balancing it with real-time data and risk management is essential for navigating the volatile crypto landscape amidst traditional market seasonality.
