Ranked against 14 sector peers with collected financials. Valuation from latest close × latest fiscal-year fundamentals; 13F conviction as of 2026-09-30.
Percentile is “goodness” within the peer set (100 = best). For valuation and leverage that means cheaper / less-levered ranks higher.

Peers = companies sharing OPXS's sector (Optical Instruments & Lenses) with collected SEC financials. Multiples use the most recent end-of-day close and latest fiscal-year fundamentals (trailing, not forward). Missing cells mean the peer never reported that line item, has no collected price, or has a non-positive denominator. Not investment advice.
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.
Solve the discounted cash flow backwards, then stress-test the assumptions.
Average free cash flow across the last 2 positive fiscal years (FY2024, FY2025). Smooths the cycle. Stock compensation is NOT charged — it is added back inside operating cash flow.
To be worth $9.14 today, the market must believe free cash flow compounds 5.1%/yr for a decade (off $3.8M on the 3-yr avg basis).
On the basis ($3.4M) the requirement is 6.6%/yr. Shares issued to employees are added back in operating cash flow, so this basis treats them as free.
The market's 5.1% is more conservative than its 7-yr track record.
Default is 10.6% — this company's computed cost of capital (computed WACC), the same rate the Analysis tab discounts at.
2-stage DCF · 0.01B shares (market data) · net debt -$6.4M
mean 3821.5% · volatility σ 8919% · implied rate exceeded in 3/6 yrs
Central path = implied 5.1%/yr growth; shaded band = ±1σ (8919%) of this company's historical FCF volatility, widening with time. The wider the band, the less certain the growth.
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.
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 $6.4M 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.
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: 21%. 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.

DuPont — the three levers
ROE 21% against ROIC 21% — 0% of the return on equity comes from leverage and buybacks rather than from the operating business.
Equity is the year-end figure. On average equity over the two year-ends, ROE is 23.9% — the two diverge when buybacks or issuance move equity during the year.

This shows debt/cash structure and net leverage. The year-by-year maturity schedule is on the Debt & Leverage tab.

Return on equity (21%) and return on invested capital (21%) are within a couple of points in FY2025, so the headline return is the operating return — there is no meaningful leverage effect to strip out.
The spread was positive in only 4 of the last 5 years.
Cash conversion of 0.55x sits below the level that would make the earnings clearly cash-backed.

Below the line, the asset base is being consumed faster than it is replaced.
Below the line for 1 year to the latest.
Depreciation here includes amortisation of acquired intangibles — goodwill written down over time, customer lists, acquired technology. Capex does not replace those and is not meant to, so an acquisitive or asset-light company sits below 1.0 permanently and correctly. The signal is cleanest for capital-intensive businesses, where the two measure the same physical base. For that reason this informs the earnings-quality verdict but never caps it.
SBC is added back inside operating cash flow, so reported free cash flow treats shares issued to employees as free. Percent of revenue says how expensive the payroll is; percent of operating cash flow says how much of the cash exists only because the charge was added back. The buyback offset is buybacks over SBC — below 1.0 the repurchase does not cover the shares issued.
Figures are the latest fiscal year (FY2025) from the company's own filings, not a trailing-twelve-month window — Q2 reads fiscal years throughout so the cash-conversion ratios and these share one basis. A blank is a line the filer did not report; it is never read as zero.

Every row is classified by what it MEANT, not by its SEC code. A code is not a meaning: code P (“purchase”) also covers dividend reinvestment and employee stock purchase plans, and code S (“sale”) also covers 10b5-1 plan sales scheduled months earlier and option exercises sold the same day.
Across 30 days of all filings, $5.08bn of insider selling contained $3.50bn of plan sales and $0.46bn of exercise-and-sell. Only 29% was discretionary. Reading an unclassified feed badly overstates how much insiders decided.
Buys and sales are counted separately and never netted. They are different decisions by different people; a company where one officer bought while another sold is not “neutral”.
The holding line carries each insider's last reported position forward, so it shows the total held rather than a sawtooth of whoever traded that day. It covers only insiders who filed in the window.
“Filed late” counts calendar days past the two-business-day deadline with five days' grace, so a Thursday or Friday trade crossing a weekend is never flagged. It describes the company's filing discipline, not the trade.
Insider activity is descriptive. Nothing here is investment advice.
