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.
Top 28 institutional holders — bubble size is position value, color is the move since last quarter. Hover any holder for detail.

Solve the discounted cash flow backwards, then stress-test the assumptions.
The most recent twelve months of free cash flow. Most current, and the most exposed to one quarter of working-capital timing.
To be worth $5.05 today, the market must believe free cash flow compounds -1.5%/yr for a decade (off $34.4M on the TTM basis).
Default is the published 10.0% — this company's own cost of capital could not be computed.
2-stage DCF · 0.08B shares (market data) · net debt -$66.3M
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 -$4.6M 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.
Operating income fell despite reinvestment — a warning on capital productivity. Current ROIC on all capital: -119%. 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 of $156.9M fully covers short-term debt of $25.1M.
Mostly long-term debt (balance-sheet current vs non-current split). A year-by-year maturity schedule wasn't disclosed for this issuer.
Debt, cash, interest and equity from the SEC balance sheet & income statement. Effective rate = interest ÷ average debt. Educational — not a recommendation.

How a revenue dollar becomes profit — FY2025
Dividends and buybacks are cash paid out, shown here against the same year's profit for scale — not funded from it.

Total return (dividends reinvested) vs the market, from quarter-end prices.
Above 0 = ahead of the S&P 500 since the window start; below 0 = behind. Rising means it's pulling ahead.
How far the stock fell below its prior peak. Deeper, longer drawdowns = a rougher ride to the same return.
Quarter-end, dividend-adjusted (total return). Beta & volatility from quarterly returns (annualized). Benchmark is the S&P 500 (SPY total return). Annual returns compound the quarters ending in each calendar year; the first and last years in a window may be partial. Past performance doesn't predict future results.

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.

DuPont — the three levers
ROE -165% against ROIC -119% — -46% 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 -91.6% — the two diverge when buybacks or issuance move equity during the year.

The metrics that matter, over time
A 30-second read on ASPN: price, valuation and headline fundamentals from SEC filings. The four questions at the top of the page are where the judgements live.
Ranked against 15 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.

Return on equity is 46 points BELOW the return on invested capital, which means the equity base is carrying capital the operations are not earning on — usually cash, goodwill, or a recent raise.
ROE is on average equity; ROIC is NOPAT over average invested capital (debt plus equity less excess cash). The gap is not a single adjustment.
ROIC ex-goodwill is -155.07% against -155.07% reported — the return is earned on a capital base inflated by what was paid for acquisitions, not by the operating business alone.
Fewer than three profitable years with a cash flow statement, so cash conversion cannot be judged.
