Vendor filing date:
If you hold or are considering CTMX, compare cash and debt across dates when reviewing its reliance on financing. Current assets can include receivables and inventory; current liabilities include bills as well as borrowings. They are not all spendable cash or all debt. These figures alone do not establish the ability to repay.
Source: EODHD’s latest stored vendor-normalized balance sheets, matched to the same security and fiscal end as these income periods. They may include restatements and are not an originally-filed or knowledge-time history. No net debt, coverage ratio or replacement balance is calculated. Read the SEC guide to financial statements for the distinction between balances and cash flows.
Company Quality Grade
How steadily did the business compound its per-share book value with dividends over 40 quarters? This historical measure is not a stock-price return or a forecast.
As of · Window to
Grade withheld by the published method. This is not a zero or a poor-quality verdict.
- A published method rule prevents admission.
excluded_window_restatement_4_02 - Book value with dividends was nonpositive, so this compounding measure could not be fitted.
nonpositive_cdabvps - A published method rule prevents admission.
series_break_equity_restated
If you hold CTMX, use this to question the durability of the business behind your investment case, alongside its filings and valuation. A withheld grade is a data or method limit, not a sell signal. For a short position, it does not predict timing, borrowing costs or downside. It does not measure your account’s return.
Method, filing sources and publication receipt
Source: SEC first-filed XBRL. Midas Edge API’s published Green Compounders method uses only filings public by the as-of date, split-adjusted shares and the original filed values. Restatements do not replace them. Issuer pools and entity types reflect the SEC submissions captured for this run, not historical classifications at each as-of date.
The primary form fits log book value with reinvested dividends against time. The method checks the starting book and market-cap floors and excludes identified non-reliance/enforcement windows. Its cohort is fixed at capture time, so historical percentiles have capture and survival limits. It does not check audit-opinion going-concern text. This grade is separate from InsiderIQ, HolderIQ and NetCredibility.
Input filings (42 in this window): 0000950170-21-000946; 0000950170-21-003053; 0000950170-22-002519. The links show up to three of the input filings.

Short-interest history
FINRA reports open short positions for a settlement date. The publication date is later. These are reported positions, with a separate date for each observation.
Compare the reported short exposure around the dates you bought, sold or watched CTMX. A long position benefits from price rises; a short position benefits from falls. A change in these counts does not predict either move.

Split-spanning counts are left uncompared. Float percentages use the stored settlement observation, not today’s float.

Dividends and stock splits
See the recorded cash amounts and dates behind CTMX’s income, and the splits that change its share count. Dates below are stored event records, not confirmation of a payment to your account.
Cash-dividend records
No qualified cash-dividend records are stored. This does not establish that the company pays no dividend.
Up to six Polygon cash-dividend events, including recorded ex-dates within the next 120 days. Amounts retain their recorded currency and decimal precision. Historical amounts are not restated to a common split basis, annualized, or converted to dollars.
For a long holding, compare the ex-date with when you held the shares and check the pay date against your broker’s cash history. Owning the stock today does not establish past entitlement. For a short holding, a dividend can create a payment obligation to the share lender.

Split history
No qualified split events are stored. This does not establish that the stock has never split.
Up to six stored split dates through Nov 10, 2026. Equivalent vendor ratios are combined; conflicting ratios are left out. This history may be incomplete.
A split changes the share count and per-share price basis; it does not by itself add investment value. Put your holding’s earlier and later share counts on the same basis before comparing them. This applies to both long shares and shares owed on a short position.

What it means for you
Sign in to read your holdings or watchlist context. No personal position or direction is inferred.
What happened
No directional recent-activity label is available. This context label is separate from the scored insider signal read.
Why it can matter
A count of reported activity describes a sample, not purchase conviction, an insider’s intent or a future price move. Neutral is not an all-clear, and absent direction is not neutral evidence.
How we got this
The current context rule reads at most 50 nonduplicate issuer/share-class records filed in the last 90 days. It counts a bullish direction or purchase code P toward bullish, and a bearish direction or sale code S toward bearish. A side must exceed the opposite count by more than two to set its label; otherwise nonzero directional counts produce neutral. Calculation unavailable for this saved label: its counts, exact records, as-of time and rule version are not supplied here. Do not substitute the separate scored read’s different window or denominator.
Where the data comes from
Stored SEC Forms 3/4/5 insider-signal records, ordered by filing date with amendment duplicates excluded. Filing date is not transaction date. The last-trade line locates recent reported activity; it does not date or reconstruct the complete count.

Moves the factor model did not explain
How much of CTMX’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.

How this split is calculated
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.
