Tom Lee’s GRNY Fund Makes MSTR Its Top Holding Before 46% Jump

Fundstrat Granny Shots US Large Cap ETF (GRNY), managed by BitMine Chairman Tom Lee, has sharply increased its position in Strategy (MSTR) just weeks before Strategy’s stock surged 46%. The move pushed MSTR from one of the fund’s smallest holdings to its largest, surpassing Robinhood (HOOD).

This raised questions about why GRNY increased its exposure, and what their strategy was behind it.

GRNY Makes MSTR Its Largest Holding Surpassing Robinhood

According to historical portfolio data shown by Bloomberg ETF analyst Eric Balchunas, Tom Lee’s Fundstrat Granny Shots U.S. Large Cap ETF (GRNY) made a major change to its portfolio during the August 2026 quarterly rebalance. 

MSTR, which previously made up only around 0.45% – 0.50% of the GRNY fund, increased to 3.02% over the last two weeks, making it the largest holding. 

The move also pushed MSTR ahead of Robinhood (HOOD), which now accounts for 2.99% of the portfolio.

In addition to the MSTR Stock Fundstrate Capital founder Tom Lee said,

“This quarter, that process led to 6 additions and 7 deletions in large-cap and 8 additions and 7 deletions in small- and mid-cap.”

Following the August 2026 rebalance, the Granny Shots portfolio grew to $5.1 billion in combined assets under management (AUM), with its flagship GRNY ETF accounting for $4.489 billion of the total.
