Does Billionaire Israel Englander Know Something Wall Street Doesn't? He Sold a Quantum Computing Stock Analysts Say to Buy.

In This Article:

Key Points

  • Billionaire Israel Englander sold 80% of his stake in Rigetti Computing in the first quarter, but every analyst following the company rates the stock a "buy."

  • Rigetti Computing believes its full-stack approach to quantum computing offers the fastest, safest path to commercialization of cloud-based quantum services.

  • Quantum computing will still be a very nascent technology in 2030, and Rigetti shares trade at an absurdly expensive valuation of 290 times sales.

In the first quarter, hedge fund billionaire Israel Englander of Millennium Management sold 1.2 million shares of Rigetti Computing (NASDAQ: RGTI), reducing his stake in the quantum computing stock by 80%. The sale represented a sharp turnaround from the prior quarter, when Englander purchased 1.4 million shares.

His decision to sell stands out because all six analysts who follow Rigetti have a "buy" rating on the stock. The target prices range from $14 per share to $16 per share, implying upside of 21% to 39% from the current share price of $11.50. Put differently, not one analyst thinks the stock is overvalued at its current price.

Quantum computers will not replace classical computers for most tasks

Classical computers manipulate binary digits (bits) to perform calculations and run operations, but quantum computers manipulate quantum bits (qubits), which can store exponentially more information. That's because bits can only be ones and zeroes, but qubits can be weighed combinations of ones and zeroes.

That a qubit can simultaneously exist as one and zero is called superposition, and that quality lets quantum computers quickly solve certain problems that would take classical computers years. Quantum computers are particularly well-suited to situations with lots of variables interacting in complex ways, such as simulation and optimization problems.

For instance, a quantum computer would be especially helpful in simulating molecules to accelerate drug discovery and material design. It would also be helpful in optimizing supply chains and logistics routes. But quantum computing will never replace all classical computing. "For most kinds of tasks and challenges, traditional computers are expected to remain the best solution," IBM said on its website.

Rigetti reported disappointing financial results in the first quarter

Rigetti builds and operates quantum computing systems. The company designed the first multichip quantum processor, and it offers cloud-based quantum computing services. Management says its full-stack approach spanning hardware and software "offers both the fastest and lowest risk path to building commercially valuable quantum computers."
