Read the insider context evidence
What it means for you
Sign in to read your holdings or watchlist context. No personal position or direction is inferred.
What happened
Stored recent-activity label: neutral. 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.

Link an account to see your stake, watchlist and past holdings. 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: the latest stored 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.

Annual cash generation
Does profit turn into cash? Compare FISN’s accounting profit with operating cash flow and capital spending. Amounts are in USD.
Fiscal year ending

- -$13.1M
- Capital spending
- $43.4K
- Free cash flow
- -$13.1M
Link an account to see your stake, watchlist and past holdings. Compare cash generation and investment needs with your thesis. Working capital and non-cash charges can separate profit from cash. Capital spending can reduce free cash flow while earnings rise. For a long or short position, that gap alone does not predict a price move.
Cash-flow source and meaning
Source: Annual financial statements, latest stored vendor-normalized figures. These may include restatements and may differ from the filer’s own XBRL. A filing date is not the knowledge date of this version of the values.
Free cash flow is the vendor’s reported figure, shown only when it agrees with operating cash flow less capital spending recorded as a positive outflow. It is not cash guaranteed for dividends or buybacks, and it does not subtract every financing obligation. Missing or sign-incompatible inputs are not filled in. An unlabelled currency is used only for a confirmed domestic USD filer. These are annual statements, not forecasts or an originally-filed history.
Cash allocation: dividends, shares and debt
Where did FISN’s financing cash go? Compare cash paid as dividends with net share and debt transactions across fiscal years. Amounts are in USD, the reporting currency. These are company-wide totals, not per-share payouts.
Fiscal year ended
Vendor filing date:
- Net borrowing / repayment
- $3.0M
- Total financing cash flow
- $30.1M
Link an account to see your stake, watchlist and past holdings. Compare these uses of cash with operating cash generation and the debt on the balance sheet. A negative net share movement means purchases exceeded issuance; it does not give gross buybacks. A dividend or share purchase can be financed with borrowing, and none of these flows guarantees a future payment or price return.
Allocation source and sign conventions
Source: Annual cash-flow statements, latest stored vendor-normalized values for the same security and fiscal year. These can include restatements; a filing date is not the knowledge date of this version.
Dividends are positive cash paid out. For net share transactions, net borrowing and total financing, positive means cash in and negative means cash out. Net share transactions combine issuance and purchases; they are not gross repurchases, a change in shares outstanding, or stock compensation. Total financing includes other flows and is not the sum of just these three lines. Zero means a reported zero. No FX conversion, shareholder-return total or forecast is inferred.

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.

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.
