Is it easy to sell a stock on the PSE?

When the company goes public, its shares can be traded in stock markets. Whether the shares will trade actively or not at all depends on many factors, including the size of the company, the market in which trading can take place, what the company is earning, and what its future prospects are. In general, however, you should be able to sell your stock easily, simply by calling a broker and offering it for sale. What price you will get for it is another question. Again that depends on many factors, including whether or not other people are willing to accept your price or if you are willing to accept the price they offer.
