About this list
- How does a company get on this list?
- A model reads each company's own description and drafts a reason it might fit. A person then approves, edits or rejects it. Core means: Uranium, nuclear fuel, reactors or nuclear generation are a main line of business. Adjacent means the theme is real business for the company, but not a main line of it.
- How often is the list reviewed?
- New drafts are made monthly. An approval lasts about a year, then that company leaves the list until it is reviewed again. Stocks that stop trading drop off by themselves.
- Is this list a recommendation?
- No. It describes what companies do. It says nothing about whether a stock is a good investment.
A person checks every company and reason on this list before it appears. Drafts come from a model reading the company's own description. A list is not a recommendation.
