For a publicly traded company, its stock price can often be a barometer of its health. There are exceptions to this rule, but a company's stock price reflects investor perception of its ability to earn and grow its profits in the future. Generally speaking, the higher the stock price, the greater the optimism about the company's prospects. As a company's stock price increases, so does its market value.


Companies receive money from the securities market only when they first sell a security to the public in the primary market, which is commonly referred to as an initial public offering (IPO). In an IPO, a company will have its own shares converted to public securities as are those granted or sold to early investors who backed the company before it went public. Pre-IPO shares can also be granted to executives, employees, family and friends.

In the subsequent trading of these shares on the secondary market (what most refer to as "the stock market"), other investors including individuals, institutions, and funds who buy and sell the stock, benefit from any appreciation in stock price. Fluctuating prices are translated into gains or losses for these investors as they shift stock ownership. Individual traders receive the full capital gain or loss after transaction costs and taxes.

The original company that issues the stock does not participate in any profits or losses resulting from these transactions, unless it is also actively buying or selling its stock on the open market. 

Inside Ownership

The first and most obvious reason why those in management care about the stock market is that they typically have a monetary interest in the company. It's not unusual for a public company's founder to own a significant number of outstanding shares, and it's also not unusual for the company's management to have salary incentives or stock options tied to the company's stock prices. For these two reasons, managers act as stockholders and thus pay attention to their stock price.

Wrath of the Shareholders

Too often, investors forget that stock means ownership. Management's job is to produce gains for the shareholders. Although a manager has little or no control of share price in the short run, poor stock performance could, over the long run, be attributed to company mismanagement. If the stock price consistently underperforms shareholders' expectations, the shareholders will be unhappy with management and look to make changes. In extreme cases, shareholders can band together and try to oust current management in a proxy fight. To what extent shareholders can control management is debatable. Nevertheless, executives must always factor in shareholders' desires since these shareholders are part owners of the company.


Another key role of the stock market is to act as a barometer for financial health. Financial analysts are constantly scrutinizing a company's performance, and their ratings on a company can affect its traded securities, which can be its shares, also known as equity, or its bonds, also known as debt. Because of this, creditors tend to look favorably upon companies whose shares are performing strongly. This preferential treatment is in part due to the tie between a company's earnings and its share price. Over the long term, strong earnings are a good indication that the company will be able to meet debt requirements. As a result, the company will receive cheaper financing through a lower interest rate, which in turn can help the company make investments for growth.

Alternatively, favorable market performance is useful for a company seeking additional equity financing. If there is demand, a company can always sell more shares to the public to raise money. Essentially this is like printing money, and it isn't bad for the company as long as it doesn't dilute its existing share base too much, in which case issuing more shares can have negative consequences for existing shareholders.

Private vs. Public Companies

Unlike private companies, publicly traded companies are vulnerable to a takeover by another company if they allow their share price to decline substantially. This exposure is a result of the nature of ownership in the company. Private companies are usually managed by the owners themselves, and the shares are closely held. If private owners don't want to sell, the company cannot be taken over. Publicly traded companies, on the other hand, have shares distributed over a large base of owners who can easily sell at any time. To accumulate shares for the purpose of takeover, potential bidders are better able to make offers to shareholders when they are trading at lower prices. For this reason, companies would want their stock price to remain relatively strong to prevent a hostile takeover from another company or individual.  

On the other side of the takeover equation, a company with a hot stock has a great advantage when looking to buy other companies. Instead of having to buy with cash, a company will use stock shares to fund the takeover. In strong markets this is extremely common - so much that a strong stock price is a matter of survival in competitive industries.

Bragging Rights

Finally, a company may aim to increase share simply to increase its prestige and exposure to the public. Managers are human too, and like anybody they are always thinking ahead to their next job. The larger a company's market capitalization, the more analyst coverage the company will  likely receive. Essentially, analyst coverage is a form of free publicity and allows both senior managers and the company itself to introduce themselves to a wider audience.
