About Inside Stocks
Inside Stocks is an editorial information service for private investors. It shows how financially solid a company is according to its published figures and how its share price compares with its own valuation history. It is not a trading venue, not an investment newsletter, not investment advice and not an investment recommendation.
Why Inside Stocks exists
Anyone who buys shares wants to know two things first: how solid is the company? And is the price currently high or low compared with what the market used to pay for this company? The answers are in the annual reports, but not at a glance. Many portals summarise them with stars, fair values or buy signals, and rarely show how they arrive at their result.
Inside Stocks takes the other route: every figure comes from the reports companies file with the US Securities and Exchange Commission, and every grade from rules fixed in advance and published here in full. It is meant for private investors who have little time and still want to know what their decision rests on. The decision itself stays with them.
Who is behind it
Inside Stocks is published by Florian Maier, Scale Smart, of Rottach-Egern, Germany, a management consultant with more than 15 years of experience in sales and strategy and an Executive MBA from the Technical University of Munich and Tsinghua University. He is responsible for the rule set, analysis and presentation. Address and contact details are in the imprint.

The principles
Rules before opinions
Every grade follows fixed, published rules. The same figures give the same grade, whoever computes it.
Quality and price kept apart
How strong a company is and how its share is valued are two questions. They are answered separately and never combined into one number.
Limits next to the results
What a figure does not show is stated right next to it, not only in the small print.
How data quality is maintained
- One source. Company figures come from the machine-readable annual reports filed with the US Securities and Exchange Commission (SEC), not second-hand.
- Recomputed at build time. Every row of the valuation calculation is recomputed when the page is built. If a row does not add up, the page is not built.
- Implausible values are not shown. If price and valuation basis do not match in currency or unit, if a stock split after the latest report is not yet accounted for, or if the market value does not fit revenue and cash flow, no value is shown rather than a wrong one, and the page says why.
- Gaps stay visible. Missing data is not estimated. The page says what is missing.
- Every change has a number. Every page states the rule set version it was computed with. Rule changes are listed on the method page.
- A test that cannot be polished afterwards. A forward test has been running since 12 Oct 2026: the selection is frozen on fixed cut-off dates and versioned with a timestamp before its performance is known.
Errors in the figures can be reported to the address in the imprint; we correct them in a traceable way.
Transparency
The publisher invests his own money in shares, including in companies analysed here, and buys and sells on an ongoing basis. For every company here, assume that he holds or has recently held shares in it. There is no statement per company, because with ongoing trading it would be out of date within days, and an outdated statement would look verified. The analysis follows exclusively from published rules with no discretion; own positions have no influence on the result. The same figures produce the same grade, regardless of who computes it and what they own.
The limits of the method and the full transparency note are in the Risk notice.
