The value of a company is the net present value of all of its future dividends.
However, we cannot know the future. The best estimate of the stock value we have is the stock price. It is the net present value of all of its expected future dividends.
If the company is expected to grow, its future growth is already built into the stock price.
Take, for example, Beyond Meat. Its employee count is 400 (Tesla is over 40 000, 100x the Beyond Meat employee count).
Yet, Beyond Meat is valued (market cap) at around 20% of Tesla. it may be a fair valuation, because meat production generates around 20% of the carbon dioxide emissions that transportation generates.
To understand why such a small company can be so valuable, you need to understand that the price of the company includes the future growth.
If growth will be smaller than the market expects, the value of Beyond Meat actually will go down!
