• Quarterly Form 13F filings let investors to way which stocks Wall Street's billionaire investors person been buying and selling.

• Headwinds look to beryllium mounting for quantum computing pure-play stocks IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc.

• Meanwhile, respective billionaires person made 1 of Wall Street's astir influential companies a halfway holding successful their portfolios.
