A Positivity Index is PositoAI's ranking of listed companies. It places every tracked company in a country in order, from #1 downwards, according to its Positivity Score, which is calculated by a highly complex proprietary algorithm using a large number of parameters. In simple words: it is one ordered list that lets you compare hundreds of companies at a glance.
What the Positivity Index is
Most investors start their research with a long list of companies and very little time. Comparing them one by one, ratio by ratio, can take days. The Positivity Index does that first, heavy step of comparison for you. Each company receives a Positivity Score, and the Index simply sorts all companies by that score. The company with the highest score is ranked #1, the next is #2, and so on.
The Index is not a single list for the whole world. Companies are ranked within their own country, so an Indian company is compared with other Indian companies, using data from the same market. PositoAI also groups companies into market-cap tiers, so you can see how a small company ranks among other small companies, not only against the giants.
How it works in practice
The Index is updated every trading day after the market closes. As prices and other information change, scores change, and so do positions in the ranking. A company can move up or down over days and weeks. That movement itself is useful information: a company climbing steadily may be worth a closer look, while a sudden fall in rank is a signal to check what changed.
Companies that have not traded on the exchange for a long time are marked "Not ranked" and left out of the Index until they trade again. This keeps the ranking based on current, real prices rather than old ones.
A simple example
Imagine you are interested in small companies in India and have 300 names to consider. Instead of opening 300 company pages, you open the Index for that tier. You see the top-ranked companies first. You pick five that interest you, open each company's page, read its details, check whether it has any regulatory red flags, and look at its financial history using Go Deep. In an hour, you have a short list that would otherwise have taken days.
Why it matters for investors
The Index helps in three ways. First, it saves time by giving you a starting order instead of a blank page. Second, it gives a consistent comparison: every company is judged by the same method, so personal bias plays a smaller role in the first filter. Third, it helps you notice change, because movement in rank often appears before you would spot it yourself.
Common misconceptions
"A high rank means I should buy." No. The Index is a research starting point, not a recommendation. A high rank says that, under PositoAI's methodology, a company currently scores well compared with others. Your own research, goals and risk tolerance still decide what you do.
"A low rank means the company is bad." Not necessarily. Some strong, well-known companies rank lower because the methodology looks at things differently from popularity or size.
"The ranking predicts prices." It does not. The Index compares companies; it does not forecast where any share price will go.
