The valuation of the company is the present value investors believe the company has. If the company is doing well, growing revenue or showing indications of future revenue (like a growing number of users or traction in a promising market), the company’s valuation will usually be on the rise. That is, the price for an investor to buy one share of the company would be increasing.
danger Of course, things do not always go well, and the valuation of a company does not always go up. It can happen that a company fails entirely and all ownership stakes become worthless, or that the valuation is lower than expected and certain kinds of shares become worthless while other kinds have some value. When investors and leadership in a company expect the company to do better than it actually does, it can have a lot of disappointing consequences for shareholders.
