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.
Solve the discounted cash flow backwards, then stress-test the assumptions.
The same 1 year 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 $4.76 today, the market must believe free cash flow compounds 53.9%/yr for a decade (off $96K on the SBC-adjusted basis).
On the basis ($295K) the requirement is 36.6%/yr. The difference is what charging stock compensation costs.
Default is 10.3% — 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 $1K
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.
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: 19%. 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.

DuPont — the three levers
ROE 29% against ROIC 19% — 10% 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 5.7% — 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.
Latest year: profit growth vs revenue growth
High operating leverage: profit moved 19.4× as fast as sales — great in an upturn, painful in a downturn.

The metrics that matter, over time
A 30-second read on RBCN: price, valuation and headline fundamentals from SEC filings. The four questions at the top of the page are where the judgements live.
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 is easily covered by operating profit. Effective rate ~2.5% on $1.6M of debt.
Cash of $1.6M fully covers short-term debt of $25K.
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.

Peers = companies sharing RBCN's sector (Semiconductors & Related Devices) 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.

Leverage and buybacks account for 10 points of the 29% return on equity in FY2022. The business earns 19% on the capital it employs; the rest is balance sheet.
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.

At $4.76, free cash flow must compound 53.86%/yr for 10 years. It has no positive compounding record after stock compensation to compare against, though across a reporting-basis change.
The percentile ranks the FISCAL-YEAR point, because the distribution behind each strip is built from fiscal-year closes — ranking a TTM figure inside it would compare two different bases. TTM basis: TTM.
The achieved growth rate spans a reporting-basis change in FY2020, so part of it measures the restatement rather than the business.
