One rating, calculated the same way every time.

In short

We apply one rules-based technical rating to stored end-of-day prices. A company appears in the Stock Selection only when its rating on the published data date is Buy or Strong Buy. The result is research information, not personal investment advice.

1. Market coverage

Coverage is defined per market: listed companies in the Netherlands and Germany, and Nasdaq-listed company shares (the whole exchange) in the United States, based on official exchange listing files. Funds, ETFs, warrants, rights, units, preferred shares and similar instruments are excluded. To be included in the selection, a company must also pass a liquidity check on its latest stored prices: a minimum closing price and a minimum 30-day average trading volume. Coverage, liquidity and a qualifying rating together decide inclusion.

2. What the rating measures

Each indicator casts a vote of positive, neutral or negative. The indicators form two groups that count equally:

• Moving-average group: price compared with simple and exponential moving averages over several periods, plus related trend measures such as the Ichimoku cloud.
• Oscillator group: momentum measures such as RSI, MACD and 10-day momentum.

The group results are averaged into one score between −1 and 1. A score above 0.5 is Strong Buy, above 0.1 is Buy; lower scores give Neutral, Sell or Strong Sell. The current method version is wstb-tr-1.0.0.

3. Enough history, or no rating

A company needs at least 220 valid trading days of stored prices. Without that it stays unrated rather than receiving an estimated result.

4. A mechanical filter

Every company rated Buy or Strong Buy on the published data date is shown. There is no manual pick. When a company no longer qualifies, it is named as Removed in the next published update.

5. Dates and cadence

The Netherlands and Germany are refreshed each weekday night from the previous trading day; the United States weekly from the Friday close. Each selection states the date its market data belongs to. Emails can arrive later than that date: member Market Updates follow published analyses and are reviewed before sending.

Limitations

The rating describes price behaviour only. News, earnings, valuation and business quality are not part of it. Technical indicators can give mixed or misleading signals, and past price behaviour does not predict future returns. A company in a list is a starting point for your own research, not a recommendation or price target.

The market-data source can change; the rating stays ours, follows the same rules and is versioned so material rule changes can be documented.
