What this transaction means for investors

DiLullo sold shares at a time when D-Wave Quantum stock was on fire.

Investors had bid quantum computing stock shares much higher as investors react to the potential of exponentially faster computing speeds and the potential for innovation on top of the progress from improvements related to artificial intelligence (AI).

Moreover, the gains point to tremendous uncertainty. As a money-losing company, it has no earnings multiple, and its price-to-sales (P/S) ratio of 325 at the time left it without a meaningful valuation measure.

Additionally, the stock had pulled back by around 30% from its 52-week high, bringing some uncertainty to its near-term direction. That and the aforementioned valuation may have helped prompt him to sell some shares.

DiLullo has kept almost 78% of his shares even after making the sale. This leaves him with some gains in case the aforementioned sales multiple points to a bubble. The fact that he kept most of his shares indicates the long-term potential of D-Wave Quantum stock.
