Market data reveals a substantial increase in options trading for MicroStrategy (MSTR) and Bitdeer Technologies Group (BTDR), signaling heightened speculative interest or hedging activity. Both companies saw trading volumes that dwarfed their typical daily averages, suggesting a concentrated move by options traders targeting specific price levels. MicroStrategy recorded 380,446 contracts, equivalent to approximately 38 million underlying shares. This represents 207.6% of its average daily trading volume of 18.3 million shares over the past month. Specifically, the $140 strike call option expiring April 17, 2026, was a primary focus, with 17,387 contracts traded.
