Shares of RGTI have surged more than 25%, doubling from a trading range of $7-$8 to around $14. The increase has been accompanied by heavy call option activity, particularly for September $16 calls, with midday buyers purchasing around 6,000 contracts at $2.64. Market participants attribute the rally to a recent Barron's story, which appears to have acted as a catalyst. Despite a 5%+ yield on the 30-year Treasury bond, which typically pressures high-growth 'quantum' stocks, RGTI's stock price and option volume have seen notable strength.
