According to Eric Balchunas, $MAGS (Mag 7 ETF) just recorded its best calendar month ever, surging 26% since April 7, known as Cramer's Black Monday (source: Eric Balchunas, Twitter, May 30, 2025). This strong performance reflects renewed investor interest in mega-cap tech stocks, which traditionally have significant correlation with major cryptocurrencies such as Bitcoin and Ethereum.
