I appreciate you for reading the article but I respectfully disagree with your thoughts on the article.

This article is more geared towards growth investors than value investors. People have said Shopify was overvalued since it was a little over $100/share and probably earlier. The same narrative rings true for many growth stocks that have since skyrocketed with some bumps along the way. This article speaks to those past experiences plenty of growth investors have had.

Consistently growing revenues, the right industry, and a respectable P/S relative to competing companies increase your chances of finding solid companies.

No investment is free from risk, and even a value stock can dramatically tumble if the right headwinds present themselves. With that said, growth stocks are known for having higher risk-reward ratio than value stocks.

Virgin Galactic and practically every EV stock is too speculative for my taste, but each investor has different preferences.

I believe in looking at the numbers (revenue and P/S for me, but they can be different for other investors) and knowing what numbers you like. P/S is better for a growth investor while P/E is better for a value investor.

I never encouraged anyone to invest large sums into any stock let alone speculative ones. Some stocks do turn $10k to $1m but I never encourage people to invest $10k into a single stock.

Everyone has their own personal criteria that they set for their portfolios. You can choose to use some of this article in your decision making process or none of it, but it's just a perspective that leans more to the side of growth investing.
