Michael Saylor’s Strategy Inc. acquired almost $1 billion in Bitcoin for a second consecutive week, as the original digital asset treasury company continues to ramp up purchases following the recent pullback in the price of the largest cryptocurrency.

Strategy Inc. shares rose as much as 2.8% in premarket trading Monday after the digital asset treasury company said it bought $962.7 million worth of Bitcoin from Dec. 1 to Dec. 7, marking its largest acquisition since July.

What began the year as one of the best trades in the stock market has, in a matter of months, turned into one of the worst.
