What this transaction means for investors
Frank Klein's sale of Rocket Lab stock appears to have little relation to the stock's performance.
Klein initiated the sale under the Rule 10b5-1 framework back in September. Thus, he avoided the appearance of acting on inside information. Also, since it was just 4% of his holdings, he likely still believes in the company's future.
However, by waiting, he missed the run-up and subsequent sell-off in the stock between April and August. Despite the aforementioned 46% return, he could have significantly increased the profits from his stock sale by selling sooner.
Also, investors have good reason to wonder whether they should follow Klein's lead. The company delayed the launch of its Neutron medium-lift rocket earlier this year. Additionally, the proposed acquisition of Iridium has faced pushback from regulators.
Rocket Lab seems to have a significant overvaluation problem. As a money-losing company, it has no P/E ratio. Still, its price-to-sales (P/S) ratio of 51 gives it a valuation that bears no relationship to the company's performance, suggesting the recent decline in the defense stock's price could continue.
