Change = this settlement’s shares short − the previous recorded settlement’s shares short; percentage change divides by that earlier count. A zero earlier count has no percentage change. Split-spanning counts are left uncompared. Float percentages use the stored settlement observation, not today’s float.

Cash bars retain the event's recorded currency and share basis. The yield line divides recorded cash in the preceding 365 days, adjusted for intervening splits, by a verified raw close in the same currency. Special dividends are included. Future ex-dates are excluded from yield. A split changes share count, not investment value. For long shares, past entitlement depends on when you held them; short shares can create a dividend payment obligation.

How much of SYRS’s move accompanied the market and its measured style leanings, and how much was left? The residual is unexplained by this fitted model. It does not establish a cause, skill or future alpha.
Return split unavailable. A complete, reconciled model for every market session in this window is unavailable. Missing dates are not filled.
Link an account with dated transactions to see what share of your own holding’s move since its purchase-date close was unexplained, with long and short positions distinguished. Your private holdings never enter this public chart.
Daily percentage returns, not window contributions. Source: the same dated warehouse rows and model v1.2.0; observed 2026-11-13T15:19:49.050Z. Absent sessions are never interpolated; missing or failed inputs stay unavailable.

Each day uses that day’s fitted market intercept and style exposures multiplied by that day’s published factor returns. Their sum plus the independently stored residual must reconcile to the stock return. Window effects are weighted by stock wealth at each day’s start and added; the stock return compounds. Every expected US market session must be present and pass source, identity, model and numerical checks. This retrospective fit is an explanation of measured returns, not evidence of causation or an investable forecast. The window ends at the latest published model session, which can lag the market; today’s unfinished session is excluded.

Prices adjusted for splits; dividends excluded.
Sep 19, 2024–Sep 19, 2025. Returns are rebased to the first displayed observation. Prices use the latest stored close's share basis, linked backward through stored price returns. Marks use their recorded calendar dates, including non-trading days; their lanes do not imply a price or that an event caused a move.
Insiders: green purchases, red sales. Other lanes: 13F reporting period ends, stored earnings-calendar dates and flagged filings. Select a mark or open the dated list for its evidence.
Reported evidence, not a forecast
Read the balances behind the trades: SEC Forms 3, 4 and 5 state a reporting owner’s position, not just an amount bought or sold. These are dated filing observations, not current holdings or a trading signal.
Ownership history unavailable. A unique active listing and SEC issuer identity are unavailable.
Link an account to see your stake, watchlist and past holdings. A reported balance adds context to a sale or purchase: an insider may still report a substantial position. This view does not calculate a percentage sold or a combined insider total. Different classes, indirect vehicles, derivatives and joint filers may overlap; changes can also reflect awards, gifts, exercises, splits or corrections. Neither a balance nor a change predicts your return.
