MSCI's Index Rule Change Puts Strategy in Crosshairs — Can a Leveraged Bitcoin Bet Survive Without Passive Money?

Shares of MST, a leveraged exchange-traded fund targeting 150%–200% of MicroStrategy's daily returns, slid 2.9% to $13.67 after MSCI adopted new rules that could boot MicroStrategy (now branded Strategy) from its widely tracked global indexes. The move threatens to cut off a firehose of passive investment dollars that flow automatically into index-listed stocks — and by extension, into funds like MST that amplify their performance. MSCI Draws a Line Against Bitcoin-Heavy Companies — What Does That Mean for a Leveraged Fund Riding Strategy's Coattails?

Shares of MST dropped 2.9% to $13.67 after MSCI finalized new index rules that could push Strategy (formerly MicroStrategy) out of its global equity benchmarks. Because MST is a leveraged fund designed to deliver 150%–200% of Strategy's daily return, any structural threat to the underlying stock ripples through at amplified force. The question now: how much damage can an index deletion do — and how much is already priced in?

• The Rule Change Targets Companies That Act More Like Investment Funds Than Businesses. MSCI approved new rules to remove companies that behave more like investment vehicles than operating businesses.

The screen examines operating assets and five financial ratios; a company that fails at least four of the five tests could be deemed ineligible.

Although Strategy continues to operate its software business, Bitcoin holdings account for an extremely large proportion of its balance sheet, making it subject to the new rule. Strategy holds 848,250 BTC — the largest corporate Bitcoin stash on Earth — so the math is not in its favor.

• Billions in Forced Selling Could Follow. When a stock drops out of a widely tracked index, every fund that copies that index must sell its shares automatically. Strategy disclosed in August that funds tracking the MSCI World Index held approximately 13 million shares, equivalent to 3.1% of shares outstanding.

JPMorgan estimates that passive funds tracking the MSCI index may be forced to sell $2.8 billion worth of MSTR stock; if other index providers adopt similar rules, the broader outflow could reach $8.8 billion. For MST holders, that selling pressure gets magnified through the fund's leverage.

• The Clock Leaves Room for Uncertainty — and Volatility. The final exclusion list arrives November 11, and changes take effect at the close of November 30.

A company can appear on the preliminary list and still stay in the index; the main uncertainty remains which firms tripped four of five ratios in their latest reports. That six-week window means MST investors face a prolonged stretch of headline-driven swings.

• Strategy Says the Impact Is Manageable — Markets Aren't So Sure. Strategy itself states that only around 3–4% of outstanding shares are held by funds tracking MSCI indexes.

The firm disputes the move, saying ETF inflows wouldn't trigger price drops. But lower index demand could make capital raising harder for treasury firms — a real problem for a company that funds Bitcoin purchases by issuing new stock and convertible debt. If Strategy's equity financing machine slows down, the growth story that MST leverages starts to crack.
