This followed the company's announcement to increase its zero-interest convertible senior notes issuance to $2.6 billion, renewing investor interest due to its Bitcoin strategy. Bloomberg analyst Eric Balchunas noted the unprecedented trading volumes, with MicroStrategy's activity eclipsing the SPDR S&P 500 ETF Trust.
