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.
Ranked against 39 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 SONO's sector (Household Audio & Video Equipment) 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.

What the company returns to shareholders — and whether it's covered by cash.
No dividend to cover. Last year: $0 dividends + $81.0M buybacks = $81.0M returned on $108.2M 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 balanced mix of reinvestment and shareholder returns.
Operating income fell despite reinvestment — a warning on capital productivity. Current ROIC on all capital: -17%. 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.

Solve the discounted cash flow backwards, then stress-test the assumptions.
The same 3 years as the 3-yr average, with the stock compensation of those years charged as a cost. Shares issued to employees are real dilution, so this asks what the business generates for existing holders.
To be worth $17.46 today, the market must believe free cash flow compounds 36.8%/yr for a decade (off $16.8M on the SBC-adjusted basis).
On the basis ($97.7M) the requirement is 11.2%/yr. The difference is what charging stock compensation costs.
The market's 36.8% is more optimistic than its 6-yr track record.
Default is 12.1% — this company's computed cost of capital (computed WACC), the same rate the Analysis tab discounts at.
2-stage DCF · 0.12B shares (market data) · net debt -$174.7M

Central path = implied 36.8%/yr growth; shaded band = ±1σ (133%) 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.

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 -17% against ROIC -17% — 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 -15.6% — the two diverge when buybacks or issuance move equity during the year.

Return on equity (-17%) and return on invested capital (-17%) 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.
No material counter-signal in the checked set: ROIC vs WACC spread, 5-year spread history, gross margin trend, operating margin trend, net margin against 3 years ago, revenue growth, ROIC ex-goodwill gap.
Missing from our data, so excluded from this answer: positive EBIT.
Fewer than three profitable years with a cash flow statement, so cash conversion cannot be judged.
No material counter-signal in the checked set: FCF / net income over 3 and 5 years, Sloan accruals, SBC as a share of revenue, SBC as a share of operating cash flow, SBC-adjusted free cash flow, free cash flow per diluted share, buybacks against SBC issued, capex vs depreciation, free cash flow against revenue, share count since the first year on file, cash conversion cycle (DSO, DIO, DPO), receivables growth against revenue growth.
Missing from our data, so excluded from this answer: 3 years of cash flow.

Operating leases are $59,623,000 of the $59,623,000 total — a fixed obligation that does not appear in a headline debt figure.
At $17.46, free cash flow must compound 37.29%/yr for 10 years. It has done -10.22%/yr over 6 years after stock compensation.
| Fiscal year | FCF growth | Price requires |
|---|---|---|
| FY2021 | 40.3% | 37.3% |
| FY2022 | 104.0% | 37.3% |
| FY2023 | −203.1% | 37.3% |

This is solved on free cash flow AFTER stock compensation ($17M against $98M before it). On the unadjusted figure the requirement would be 11.66%/yr. Which is right depends on whether you think the share issuance is a recurring cost of running the business.
