Fiscal year

How to read it: the width of a band is the size of the amount. Gross margin 71 %, operating 61 % — the difference was eaten by the items at the bottom right. On the left, products from the annual report with year-on-year change.

Eight rules

7 of 8

Seven rules met. The seventh is not: there is a loss in the earnings-per-share series, and that cannot be turned into a percentage — the page says so instead of printing a number.

How to read it: only open-market buys and sells for the person's own money go into the totals. Granted shares, exercised options and tax withholding are pay mechanics and Qvestor marks them separately in the table. The six largest of 46 sells.

A demo on SanDisk from its annual report and SEC filings. Qvestor does the same for any company that files with the SEC.

WHAT ELSE IT DOES

One company at a time, from the filings up.

Any SEC filer

Ticker, name, or CIK

Suggestions search the whole SEC list. A company nobody has opened yet is pulled from its filings in a few seconds.

Price

1D to MAX, against the S&P 500

Price and volume, no technical analysis. The dotted index line shows whether the stock rose with the market or on its own.

Income statement

Quarters and years, revenue by segment

Revenue, gross and net profit, earnings per share, cash flow. Revenue split by segment, region and product with year-on-year growth.

Valuation

On a scale, not in a paragraph

P/E, P/S, P/FCF and P/B against the median of industry peers and against the company's own five-year history.

The people

Analysts and the price reaction

Consensus, target price, earnings per share against the estimate, and what the price did the day after results. Marked as someone else's view, not ours.

Balance sheet

Debt, cash, buybacks, dilution

Will the company survive a bad year? Cash against debt, working capital, and how many shares were added or retired.

Screener

A filter over every opened company

P/E under 15, margin above 20 %, growth above 10 %. The universe is named honestly: companies Qvestor has measured, not the whole market.

Portfolio

From your broker, read-only

Trading 212, Webull and eToro. Positions, cash, weights, and a Grows · Earns · Survives rating on every holding.

Watching

Comparison, events, Monday brief

Two companies side by side, new filings and earnings dates for watched companies, and one e-mail a week with what changed.

What the tool cannot work out, it says out loud. A blank is an answer, not a fault — for a bank that reports no gross margin there is a dash and a reason, not a zero.

One subscription. No lock-in.

WHO MAKES IT

One author, one method.

Qvestor is a tool by Salamon Capital. How we calculate is on the Method page; what we hold is on Conflicts of interest. The author holds a position in SanDisk as of the demo date and says so at the top, not in a footnote.

Qvestor is not investment advice. It shows what the company reported; the decision is yours.

Check the company yourself, before you buy it.
