Quantum computing names are among the stocks to watch heading into the new trading week, after a MarketBeat screener ranked them by the highest dollar trading volume in recent days.
The screen names IonQ, D-Wave Quantum, Quantinuum, Quantum Computing Inc. and Horizon Quantum Computing. IonQ sells access to general-purpose quantum systems through AWS Braket, Microsoft Azure Quantum, Google Cloud Marketplace and its own cloud, while D-Wave offers its Advantage fifth-generation system, Ocean open-source tools and the Leap cloud service. Quantum Computing Inc. is an integrated photonics firm offering portable, low-power, room-temperature Dirac entropy quantum computers, along with quantum random-number generation and authentication products.
The screener itself flags the risk in the sector: the technology is still developing, commercialisation timelines are uncertain, and many firms have limited revenue and profitability. The list is a volume screen, not a recommendation to buy or sell.
Separately, insider buying disclosures compiled from SEC Form 4 filings show Dai Kun, chief executive of Prothena (PRTA), bought 90,000 shares on October 8 at an average $8.57, for a total of $770,904, bringing his holding to 529,000 shares.

These are disclosed transactions reported for information only.
