A 94% gain in a single trading session is enough to turn heads. For one ultra-small-cap ETF, however, Friday’s explosive move in a tiny portfolio holding translated into something closer to a scratch-off jackpot.
Shares of The Marygold Companies (NYSE:MGLD) jumped about 94% on Friday. Bloomberg Intelligence ETF analyst Eric Balchunas highlighted the move on X, noting that no ETF appears to have exposure to the stock, with the EA Bridgeway Ultra-Small Company Market ETF (BATS:BUSM) being the only exception.
The catch? BUSM’s position was tiny.
Marygold’s latest available ownership data showed BUSM holding 54,039 shares, equivalent to about 0.05% of MGLD’s outstanding stock.
That means Friday’s 94% surge would add only about $50,800 to a position of that size, assuming the holding remained unchanged. Against a diversified portfolio, the impact is therefore modest — exactly the kind of “nice, but not life-changing” gain Balchunas was getting at.
Trading volume of MGLD shares on Friday reached an impressive 13.1 million shares, indicating heightened interest and participation in the stock, according to Benzinga Pro data. MGLD’s fundamentals provide some additional context for why the stock has been attracting attention. The company reported 8% fiscal 2026 revenue growth to $25.3 million, while its USCF Investments business posted 23% revenue growth. Average assets under management at the fund-management business rose 41% to $4.1 billion.
The episode also illustrates the peculiar math of ultra-small-cap ETFs. A position representing only a fraction of a percent can suddenly become one of the portfolio’s biggest percentage winners when an obscure microcap doubles in a day.
For BUSM, Friday brought the fireworks. The position, however, was small enough that the champagne probably came in a miniature bottle.
