Amazon: An Overview

Amazon (AMZN) is easily the most well-known online retailer in the world. The company was founded in 1994 by Jeff Bezos, who originally ran it out of his garage. It's now become one of the world's leading influential companies, and also runs web and cloud computing services, along with artificial intelligence operations.

It became the second company to hit $1 trillion in market value on Sept. 4, 2018, close on the heels of Apple, which achieved this feat in early August. But in the 20-plus years since its initial public offering (IPO), Amazon stock was not always the hot commodity it is today. When Amazon first went public in 1997, its stock was priced at just $18 per share.

From that modest beginning, the online retail giant has seen its stock skyrocket, despite a rocky period during the dotcom crash. The company's stock has reached the four-digit mark, hitting a new high of $3,103.85 per share on January 12, 2021, during intraday trading.

Hidden Growth

If you invested a simple $100 in Amazon's IPO in 1997, you would have received five shares. That investment would have been worth $129,186 at the end of the trading day on February 20, 2020, when shares closed at $2,153.10 each. That would yield an increase of more than 129,000% on the initial $100 investment. became one of the first companies to reach $1 trillion in market cap, and its founder, Jeff Bezos, is the richest person in the world, as of July 10, 2021.

It's clear from these figures that even a modest investment in the company in 1997 would have turned into a healthy contribution to anyone's retirement savings. In fact, with the new high of $2,185.10, the share price grew almost 12,040% since its IPO.

To make sense of how a modest $100 investment can grow into such a hefty amount, it helps to understand the mathematics behind one of the most powerful facets of stock market investing—the split.

Stock Splits: The Basics

A stock split occurs when a company decides to issue additional shares to current shareholders in accordance with the number of shares already owned. A 2:1 split means shareholders receive an additional share for every share they already own. An investor who owns 100 shares, for example, ends up with 200 shares. Stock splits can be as generous as the company that issues them wishes, but the most common are 2:1 or 3:1 ratios.

When a stock splits, its price is reduced by the same factor. So a 2:1 split means shareholders have twice the number of shares valued at half the price so the total value of the shares remains stable.

On the other hand, a 3:1 split means the stock price is reduced to one-third of the original value. While the price of a share is initially reduced by a split, the value—or market capitalization—does not change much. What does change, though, is that an investor who used to own one share now has two or three depending on the split factor.

Companies may announce a split for numerous reasons. The primary reason, though, is the desire to keep stock attractively priced for investors. When a company's stock reaches lofty levels like Amazon's stock, it becomes harder for investors to afford, especially new ones. The other reason is to make the stock much more liquid and thus increase the number of outstanding shares.

Amazon Does the Splits

Amazon's stock split three times in quick succession. The first split took place in June 1998. For its first stock split, Amazon offered two shares for every one share held. That means your hypothetical original investment of $100 in the IPO would have gone from five to 10 shares.

The next two stock splits Amazon announced took place in January 1999 and then in September of the same year. The first of these two was a three-for-one split. That would mean that if you held onto all your shares, you would now own 30 shares—10 from the original split multiplied three times. The next was another two-for-one split, which would have increased your ownership to 60 Amazon shares.

As noted above—and not to rub any salt in your wounds—those 60 shares would be worth $129,186 at the end of the trading day on February 20, 2020. Remember, that's more than 129,000% on the initial $100 investment.

The Bottom Line

While there is a possibility of impressive gains like with Amazon's story, IPOs are highly speculative and unproven. Not all companies have an IPO that can guarantee you riches. Amazon has defied the odds and has arguably been the most successful public company in modern history.
