The Space Exploration Technologies Corp Trade Ark Invest significantly boosted its exposure to SpaceX, purchasing 44,196 shares in ARK Innovation ETF (BATS:ARKK). The stock ended Tuesday at $149.47, making the transaction worth nearly $6.6 million.The move comes as investor interest intensifies around the Elon Musk-led company’s internal dynamics, including its hidden internal "30% rule" shaping investor expectations, which may influence future valuation events and liquidity scenarios.Under the company’s IPO agreement, approximately 912 million shares (about 20% of eligible non-affiliate holdings) are scheduled to become eligible for sale on Aug. 5, two trading days after earnings. However, if SpaceX shares close above $175.50—30% above the $135 IPO price—on five of the 10 trading days leading up to earnings, another 456 million shares (an additional 10% of eligible holdings) will be unlocked on Aug. 7.The clause means that strong share-price performance, rather than weakness, could significantly increase the number of shares eligible to enter the market shortly after earnings, potentially adding to selling pressure.Notably, Ark purchased 917,000 shares of SpaceX on Monday.The Advanced Micro Devices TradeArk Invest reduced its exposure to AMD, selling 8,667 shares from ARKK. At a closing price of $516.11, the transaction was estimated at nearly $4.5 million.The move follows recent downward pressure on the semiconductor stock, with concerns outlined in recent weakness in AMD stock driven by market sentiment shifts. Jim Cramer recently described the dip as a buying opportunity, citing sustained demand for AMD’s CPUs and GPUs.Investors are also looking ahead to AMD’s Aug. 4 earnings report, with Wall Street expecting EPS of $1.55 on $11.28 billion in revenue. Analysts continue to maintain a Buy consensus, with recent price target increases from Goldman Sachs, Wells Fargo and Cantor Fitzgerald, although AMD’s premium valuation leaves the stock susceptible to volatility during risk-off periods.On Monday, as part of an ongoing trend, Ark dumped $8.6 million worth of AMD stock.Other Key Trades
