How my analyses are made

by Alien Investor · as of 23 Oct 2026

This page explains how my stock analyses, my Bitcoin analyses and the Alien Analyzer work: where the numbers come from, what is fact and what is my assessment, which assumptions sit behind a fair value, and where I have interests of my own. Every analysis links to this page.

What an analysis is and what it is not

Facts, estimates, opinion

Every analysis contains three kinds of statements. I keep them apart:

KindExamplesHow it is marked
FactsRevenue, earnings, debt, dividends, segment figuresfrom annual reports and mandatory filings, with the data date
EstimatesFair value, price scenarios, forecasts, analyst expectationslabelled as a model calculation or estimate, with the assumptions; third-party forecasts with source
OpinionMoat, management, risks, the Alien verdictworded as my assessment

Values I cannot back up with a source are marked as an estimate or as not available, instead of inventing a number.

How I value

Fair value

The fair value in my analyses is a model calculation, not a price target. It is based on the fair value indicator of the Alien Analyzer:

Fair value = current earnings per share × median of the historical P/E ratio in the selected period, excluding outliers (default: 10 years)

The assumptions behind it:

Both can be wrong: for cyclicals at an earnings peak or trough, after one-off effects, when growth breaks or when the interest rate environment changes. That is why I check the indicator in every analysis against the P/E history of recent years and put it into context in the text instead of taking it over unchecked. When an analysis names a price scenario, its assumptions are stated in the text.

Metrics and quality check

For context I use historical valuation multiples (P/E, P/CF, P/S, P/B), the dividend history and a quality check covering return on equity, debt, free cash flow, equity ratio, earnings growth, dividend yield and the change in share count. The traffic-light colours in the analyzer follow fixed rules: mostly fixed thresholds, for P/E a comparison with the stock's own average and the sector P/E, and special rules for some sectors. For banks, insurers, REITs, commodity companies and other special cases, some metrics do not fit. The analysis says so.

Bitcoin analyses

Bitcoin is not a stock. There are no earnings and no P/E ratio. My Bitcoin analyses are based on the price history, on the power law model and on publicly available market data.

I hold Bitcoin. Every Bitcoin analysis says so as well.

Conflicts of interest

Date and timeliness

The top of every analysis states the data date. Prices and metrics refer to that point in time. The disclosure block states the date and time of publication, after a full revision also the time of that revision, plus the date of the disclosure itself.

Alien Analyzer

The Alien Analyzer V2 calculates automatically for every ticker you enter. It knows neither you nor your goals.
