Michael Ewing Purves is a person, just like you and I, who works in the financial world. He helps people make important decisions about money by understanding how the stock market works.
The stock market is like a very big store, where people can buy and sell something called "stocks" or "shares" in different companies. When you buy a piece of a company, you become a partial owner of that company. When the company does well, the value of your piece or “share” increases, and when it does poorly, it decreases.
Michael Ewing Purves helps people understand how the stock market works, the different types of companies that a person can own a share in, and how to make smart decisions about what to invest in. He does this by looking at a lot of information like charts, graphs, and news about the companies, and then using all of that information to make smart financial decisions for his clients.
So, to put it simply, Michael Ewing Purves is a person who helps other people make smart decisions with their money and investments, by understanding how the stock market works.
