E-commerce is short for electronic commerce, the act of buying and selling products and services over the internet. It includes all the individual actions we might take for granted at a store:

Selecting the product
Paying for the product (or receiving payment)
Getting the product into the buyer's hands
Customer service
And more

E-commerce has upended the way consumers spend their money. This new world of shopping has disrupted the entire retail sector, turning heroes to zeroes (really) and elevating some providers, founded entirely on the industry's promise, to the ranks of the largest companies in the world.

E-commerce is a winning trend

E-commerce is a trend whose time has come, and it presents serious opportunities for savvy investors. Some of you might think of Amazon's massive size and dominance of the market and worry that you've missed the boat -- but just remember that there's still a huge opportunity not only in the U.S. but also around the world. While there is no guarantee how these companies and their stocks will perform in the short term, they've each demonstrated their strength -- and we think they've shown they have what it takes to deliver market-beating returns over the long term.
