A key early investor has sold the last of its Tesla shares and sharply reduced its SpaceX holding, taking profits from two of its most successful long-term bets.

Scottish Mortgage Investment Trust , a London-listed closed-end fund managed by Baillie Gifford, said Friday that SpaceX represented 11.1% of its total assets as of Wednesday, down from 15% at Sept. 30.

The position helped drive Scottish Mortgage's 31.5% net asset value return in the six months to the end of September. In its half-year results statement, Scottish Mortgage also said it sold its remaining Tesla stake in April, ending an investment that dated back to 2013.

SpaceX windfall

Scottish Mortgage first invested in SpaceX in December 2018, when Elon Musk 's rocket company had a reported valuation of about $31 billion, and committed roughly $200 million through 2021.
