Rocket Lab Corporation enters the week of July 15 with two diverging signals pulling in opposite directions: the founder and CEO has been selling heavily into a stock that has lost nearly a quarter of its value over the past month, while short sellers have been quietly and steadily rebuilding positions throughout the same decline.
The insider story is the most concrete data point here. Peter Beck, Rocket Lab's founder, chairman and CEO, sold approximately $120 million worth of shares across a cluster of transactions on July 7 and 8, when the stock was trading in the $81-$88 range — well above Tuesday's close of $78.81. The sales spanned multiple tranches and price points, suggesting a structured programme rather than a single opportunistic exit. Over the past 90 days, net insider selling totals roughly $303 million. That scale is notable even for a founder who holds a large position, and it lands at a moment when the stock has given up 23% over the past month.
Short sellers have been moving in the same direction. Short interest as a percentage of the free float has risen from around 5.7% at the start of June to 8.7% now — a jump of more than 50% in six weeks. The weekly increase alone is nearly 12%. That is a material and sustained rebuilding of bearish positioning, not noise. Yet the lending market tells a contrasting story: availability remains generous, running at 360% relative to outstanding short interest, well clear of the tightest levels seen over the past 52 weeks. Cost to borrow is only 0.52% — essentially free. Shorts are building, but they are not yet fighting for scarce supply, and there is no meaningful squeeze pressure visible in the borrow market.
Options positioning has tilted slightly more bullish than usual, providing a quiet counter-signal to the short rebuilding. The put/call ratio has dropped to 0.70, about 1.1 standard deviations below its 20-day average of 0.73 — the most call-heavy reading in several weeks. That divergence is worth noting: as short sellers add exposure, options flow has moved the other way. The ORTEX short score, at 51, has edged higher over the past week but remains squarely in neutral territory, not flagging an extreme positioning read in either direction.
The Street view adds context to why the stock has re-rated so sharply. Rocket Lab's EV/EBITDA multiple, while still an eye-watering 1,277x, has compressed dramatically — down more than 3,300x over the past 30 days — as the share price has pulled back. The P/B multiple has also contracted by 17x over the same period. The company remains pre-profit, with a negative earnings yield and no dividend. Factor scores reflect the tension: EPS surprise ranks in the 92nd percentile, pointing to a strong track record of beating estimates, while the short score rank (20th percentile) and dividend score (26th percentile) show the offsetting headwinds. A recent note flagged Rocket Lab's acquisition of Iridium as a potentially transformative strategic move, expanding the company beyond launch into satellite operations — but also raising integration risk questions heading into the Q2 results now set for August 6.
Among closely correlated peers, the week has been broadly difficult. LUNR fell 16.5% and FLY dropped 16% on the week, both sharper declines than RKLB's 5.5% slip. VOYG and RDW held up better, down 6.6% and 4.6% respectively, suggesting the selloff has been uneven across the space sector rather than uniformly indiscriminate. RKLB's relative resilience against its highest-correlation names is a small point in its favour, though it has done little to offset the broader momentum reversal since mid-June.
The August 6 earnings print is the next meaningful event. Rocket Lab has posted strong post-earnings reactions recently — the May print saw the stock rise 11% the next day and nearly 25% over the following five days. With short interest at an eight-week high, borrow conditions still loose, and Beck's selling now on record, the setup into that report will be the defining test of whether the current repositioning reflects genuine concern or simply routine profit-taking after a long run higher.
