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.
This company doesn't have positive free cash flow, so a reverse DCF can't be run.
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.
Is the value real, and is the business safe? Academic scores + earnings quality + solvency, from SEC filings.
1/7 of the 9 checks — 2 couldn't be scored (see above), so the score is out of the 7 with data.
Safe > 2.99 · grey 1.81–2.99 · distress < 1.81
Needs granular two-year detail (receivables, PP&E, D&A, SG&A) — not fully reported.
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 -$20M 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: 3%. 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).
Thin coverage — earnings barely cover interest. Interest last disclosed in FY2022 (no longer broken out).
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.

Where each multiple sits in its own 9-yr range
Dot = today · shaded = middle 50% · line = median. Lower percentile = cheaper vs its own 9-yr history.
Is the profit real, and how strong is the balance sheet?
FY2025 · every deduction from revenue to net income
DuPont — the three levers
Watch the leverage lever — a chunk of ROE comes from the balance sheet.
What the company owes vs. what it holds
Year-by-year maturities aren't in SEC companyfacts (footnote-only), so this shows the debt/cash structure and net leverage instead.
Latest year: profit growth vs revenue growth
Operating leverage needs meaningful revenue change.

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.

Peers = companies sharing BYSI's sector (Healthcare) 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.
