And any such rating can be divided into fifths, or quintiles. The fifth or lowest quintile would include the 20 percent of the population who make the least money or eat the least ice cream or generate the least trash, and the first quintile would include the 20 percent who make, eat, or generate the most.

Financial Definition of quintile

What It Is

A quintile is one of five equal parts.

How It Works

For example, if we were to look at all of the closing prices for Company XYZ stock for every day in the last year, the top 20% of those prices would represent the upper quintile of the data. The bottom 20% of those prices would represent the lower quintile of the data. There would be three quintiles in between the upper and lower quintiles. The average of all the stock prices typically falls right in the middle, between the second and fourth quintiles.

Why It Matters

Quintiles are crucial for studying economic data, income data, stock data, and virtually any other kind of financial information. By breaking things into quintiles, an analyst can make a variety of inferences about the data and how the observed item behaves.
