STRC is sub-par ($99.53 vs the $100 threshold), so the preferred ATM is dark. MSTR is running actively at mNAV 1.49 — Strategy is running at roughly $96M/day, on pace for $480M and about 6,179 BTC this week. Week is now complete.

Last week's story April 20–26, 2026
A quiet week. $255M raised — all from MSTR (1.45M shares). All four preferreds paused: STRC stayed below its $100 par threshold so the algo gated to zero, and STRF/STRK/STRD were also dormant. The MSTR-only proceeds bought 3,273 BTC at a $77,906 average, lifting cumulative holdings to 818,334. Sharp pivot from the prior week's $2.54B / 34,164 BTC / STRC-dominant raise.

Dividend at Par

Annualized declared rate — what each preferred would yield if priced at $100. STRF/STRK/STRD are fixed coupons; STRC resets monthly. Each line begins at that preferred's launch date.

Solid pink: STRC's variable rate, reset monthly by Strategy's Board (rate steps from data/disclosures/strc_div_rates.csv, derived from declared monthly ex-dividend amounts). Dashed lines: fixed coupons from each preferred's IPO prospectus (STRK 8.00%, STRF 10.00%, STRD 10.00%). Launch dates: STRK Feb 3, STRF Mar 26, STRD Jun 6, STRC Jul 30 (all 2025).
How each ATM works Plain-English mechanics for all five programs
How the whole system works

Strategy files an 8-K every Monday with the prior week's ATM totals — nothing in between. To stay ahead of the next filing, the model reverse-engineers each program from public price & volume plus the latest 8-K. Each ATM has a known gating rule: mNAV premium throttles MSTR, a $100 par threshold gates STRC volume capture, STRF/STRK split via a logistic hurdle on relative effective yield, and STRD runs a fixed baseline cadence.

STRC's algo is pinned to its observed ~55% volume-capture rate above par, so the other four overlays calibrate around a fixed STRC contribution — one anchor, four free parameters, refit weekly as each new 8-K lands. The combined output is a forward forecast of this week's raise per program, and the BTC those proceeds will buy.

MSTR common stock · no coupon · voting

Common stock ATM — Strategy's main equity lever. Issuance gates on mNAV premium: ramps when MSTR trades well above BTC book value, throttles as the premium compresses, and effectively stops when mNAV falls below 1.0 (dilutive).

STRC variable-rate monthly-reset preferred · "Stretch" · par $100

Issues only on days STRC closes at or above its $100 par threshold. The algo captures ~55% of daily volume × close on eligible days, net of fees — and pauses entirely below par. Largest raise capacity ($19.5B) so it dominates whenever price holds above par.

STRF 10% cumulative preferred · "Strife" · par $100

Shares a logistic-hurdle allocation with STRK. Their weekly split is driven by relative effective-yield z-score, liquidity share, premium-to-par spread, and time since STRK launch. STRF is the high-yield anchor of the pair.

STRK ~8% convertible preferred · "Strike" · par $100

Convertible into MSTR common at a fixed strike. Pairs with STRF under the logistic hurdle model; STRK wins share when its effective yield cheapens vs STRF or when MSTR rallies (the embedded call option gains value).

STRD ~10% non-cumulative preferred · "Stride" · par $100

Runs on a locked baseline cadence — small, steady issuance rather than reacting to market signals. Drift-monitored only; Strategy dips into STRD opportunistically when the other preferreds are capped or gated.
