In a Rare Day, Bitcoin Outperforms the S&P 500

According to Arzdigital, published on Tuesday, 18 August 2026 (27 Mordad 1405), Bitcoin posted a rare day of sharply outperforming the S&P 500 on Monday, 17 August (26 Mordad). While Bitcoin climbed to around 64,000 dollars, the Wall Street benchmark fell 0.52 percent, a divergence the report called Bitcoin's best daily performance in more than a month. Per Sahmino's own recorded data, Bitcoin traded at 64,871 dollars as of 19:38 Tehran time, up 0.8 percent on the day.

Arzdigital, citing analysis from blockchain analytics firm Glassnode, said Bitcoin has outperformed the S&P 500 on only about one third of trading days over the past three months, despite historically moving in high correlation with the equity rally. Analysts attributed the relative underperformance to capital flowing into Wall Street's AI stock rally and to Bitcoin's four year cycle entering a bearish phase after its roughly 126,000 dollar peak last October.
