Stock Companion vs AltIndex

Both tools help you decide what to do with a stock, and they go about it differently. This page says which is which, including the parts where AltIndex is the better choice.

What AltIndex is

Scores stocks using alternative data — web traffic, app downloads, social mentions and job postings — and turns it into an AI score per company.

What AltIndex does better

Breadth of alternative data. AltIndex watches signals that never appear in a headline at all, like how many people downloaded a company's app last month, and that is a genuinely different lens on a business from the one news gives you.

What we do that they do not

Every headline behind our number is listed with its own score, so you can read the thirty articles that produced a ticker's sentiment rather than trusting one composite. The signal shown on a ticker page is the same one every visitor sees, and it is free to look at.

Which to pick

Stock Companion is the better fit for someone who wants headline-level transparency rather than a composite of app and web data. If what you want is the thing AltIndex does better above, use AltIndex — plenty of people sensibly use both.
