Total shares institutions bought (green) vs sold (red) each quarter across all holders.
Inferred from quarter-over-quarter change in each fund's 13F position (new stakes count as buys, exits as sells). Not tick-level trades.
How management deployed cash over 10 years — and what it earned on reinvestment.
A reinvestment story — most cash went back into growth rather than to shareholders.
Reinvestment has been productive — operating income grew well per dollar put in. Current ROIC on all capital: -14%. Rough measure (includes maintenance capex).
Cash uses aggregated from the SEC cash-flow statement over 10 fiscal years. "Return on reinvestment" is a rough proxy — operating-income change ÷ cumulative CapEx + M&A — and includes maintenance capex. Educational — not a recommendation.
How much the company owes, how it's trended, and how comfortably it's serviced.
Insufficient EBITDA/debt history.
Green ≤ 1.5× · amber ≤ 3× · red > 3× (leverage relative to cash earnings).
Interest expense isn't separately reported — often netted into “other income (expense), net.”
Cash vs short-term debt unavailable.
Short-term / long-term split not separately reported.
Debt, cash, interest and equity from the SEC balance sheet & income statement. Effective rate = interest ÷ average debt. Educational — not a recommendation.
Solve the discounted cash flow backwards, then stress-test the assumptions.
To be worth $2.70 today, the market must believe free cash flow compounds 12.0%/yr for a decade (off $7M normalized FCF).
2-stage DCF · 0.08B shares · net debt -$15M
Reverse DCF: rather than guessing a fair value, we solve for the growth the current price implies, then you stress-test the assumptions. Enterprise value of the FCF stream, less net debt, ÷ shares. Educational — not a recommendation.
Is the value real, and is the business safe? Academic scores + earnings quality + solvency, from SEC filings.
1/8 of the 9 checks — 1 couldn't be scored (see above), so the score is out of the 8 with data.
Safe > 2.99 · grey 1.81–2.99 · distress < 1.81
Eight indices comparing this year to last (receivables, margins, asset quality, growth, accruals, leverage). Above −1.78 suggests possible manipulation; below −2.22 is clean.
A screen, not proof — high growth alone can raise it.
Cash-conversion data unavailable. Lower/negative accruals = higher quality (Sloan).
Coverage data unavailable.
F-Score (0–9 fundamental momentum), Altman Z (distress risk), and Beneish M (earnings-manipulation screen) are academic models computed from the SEC filings. Screens and context — educational, not recommendations.
What the company returns to shareholders — and whether it's covered by cash.
No dividend to cover. Last year: $0 dividends + $0 buybacks = $0 returned on -$14M FCF.
Yields use the latest fiscal-year dividends/buybacks over current market cap. Dividends and buybacks from the SEC cash-flow statement; payout coverage vs net income and free cash flow. Educational — not a recommendation.
Top 40 institutional holders — bubble size is position value, color is the move since last quarter. Hover any holder for detail.

Ranked against 1085 sector peers with collected financials. Valuation from latest close × latest fiscal-year fundamentals; 13F conviction as of 2026-03-31.
Percentile is “goodness” within the peer set (100 = best). For valuation and leverage that means cheaper / less-levered ranks higher.
