Explain Me the Map FAQ About

An interactive map about institutional investors and their engagement in the stock market

Introduction

At first glance, the map looks like a giant QR code, yet its significance runs far deeper: each dot on the map represents an investment or hedgefund company. Together they represent 75% to 80% of the U.S. stock market, rendering the map a powerful visualization of a vast swath of the market. Click on a dot to view its top 100 holdings. The size of each dot corresponds to the company's assets under management (AUM).

A larger dot means the investment company has a larger amount of assets under management

Dot Brightness

The dot's brightness indicates the diversity of the investment company's portfolio, with brighter dots representing a wider range of holdings.

A bright dot means the investment company has many holdings, a darker dot means the investment company owns only a few different equities in its portfolio.

Similarity

Hedgefund companies holding similar stocks or mutual funds are positioned closer together on the map. The absolute position of dots does not play a role only their relative postion to each other is important.

If two investment companies, A and B, have similar positions in their portfolio their dots will be near to each other.

Dissimilarity

Conversely, companies with little to no overlap in their holdings are placed farther apart. The absolute location of each company is irrelevant; only their relative positions to one another matter.

If two investment companies, A and B, have very different positions in their portfolio their dots will be further apart in the map.

Clusters & Empty Cells

Some cells of the map are empty. This helps to form distinct clusters of hedgefund companies that share equal traits. More details about the clustering process can be found here.

The map has some empty spaces.
