"Classic Growth Stocks: Google, Tesla, and Amazon
The vast majority of growth companies reside in the technology sector where rapid innovation and growth spending is typical. Google, Tesla, and Amazon are three classic examples of growth companies because they continue to focus on investing in innovative technologies, sales growth, and expansion into new businesses.
While these three growth stocks have more expensive valuations than the S&P 500, Google, Tesla and Amazon are also the leaders in their respective niche industries. Google is continuing its technology conglomerate-status by expanding into new technologies such as
artificial intelligence. Tesla is the popular electric car maker and undisputed leader of the industry. Meanwhile, Amazon continues to disrupt the retail sector through its
ecommerce platform, which takes away business from traditional brick-and-mortar retail competitors."
