2 Monster Growth Stocks to Buy Now and Hold Forever

The Pareto Principle -- also called the 80/20 rule -- was first proposed back in 1896 and it has been found to hold true when applied to a number of different areas, including sports, computing, healthcare, and especially economics. One application of it in economics suggests that about 80% of the market's gains at any given time are driven by 20% of the market's stocks.

This is part of why many investing firms emphasize the need for diversification in a portfolio. No one knows for certain which stocks will be in that 20% group generating monster returns for shareholders. While there is no absolute certainty out there, we can make some strong educated guesses about which stocks are in the 20%, and it's pretty clear that Zscaler (NASDAQ: ZS) and Upstart Holdings (NASDAQ: UPST) have massive upside potential. Let's take a closer look at these two monster stocks.

Zscaler operates the largest network security cloud in the world. Its Zero Trust platform, known as a secure access service edge (SASE), accelerates and secures access to applications and infrastructure, allowing employees to connect to corporate resources and the open internet from any device or location. Moreover, by delivering security from the cloud, Zscaler eliminates the need for costly on-premise hardware.
