A machine designed to run in one condition
Strategy's engine is simple to state: sell shares at a premium to the Bitcoin behind them, buy Bitcoin with the proceeds, and Bitcoin per share rises for everyone. The whole flywheel depends on that premium existing. When the stock trades near — or below — the value of its net Bitcoin per share, the same trade reverses: each new share issued to buy Bitcoin dilutes existing holders' Bitcoin per share, because convertible debt and $15.5 billion of preferred stock hold senior claims on the treasury.
That is the state the company has been navigating. Its July 20 filing shows 2,732,318 shares sold for approximately $263.5 million between July 13 and 19 — with zero Bitcoin purchased. The proceeds went to the USD reserve instead, now $3.225 billion.
The metric that matters
The honest scoreboard for a treasury company is Bitcoin per share. Strategy's own reporting showed a year-to-date BTC Yield of 13.3% as of May 25 — genuinely strong. But issuing stock to build a cash reserve rather than to buy Bitcoin adds shares without adding coins, and July's first programmatic Bitcoin sales subtract coins outright. The direction of that metric between now and year-end is, in Signal21's view, the single best indicator of whether the model is working through this phase or eroding.
The medium-term case
This is the core of the Bearish Bias on the 1–6 month horizon. The accumulation engine is idling; the balance sheet is being defended, not extended. If Bitcoin follows the deeper pullback scenario in Signal21's medium-term Bitcoin view, MSTR would face it with its cheapest capital tools unavailable — and history suggests the equity amplifies what Bitcoin does, in both directions. The long-term Strong Bullish view assumes this phase is survivable and temporary; the medium term is where that assumption gets tested. This is market analysis, not a recommendation to buy or sell any security.
