Stock shares股票份额

A company's stock share is a piece of the company; more precisely:
一家公司的股票份额是该公司的组成部分；更精确地说：

A stock (also known as equity) is a security that represents the ownership of a fraction of a corporation. This Entitles the owner of the stock to a proportion of the corporation's assets and profits equal to how much stock they own. Units of stock are called "shares." [1]
股票（也称为股权）是一种代表公司一部分所有权的证券。这 使股票持有人有权获得与所持股票数量相等的公司资产和利润的比例。"股份"是股票的单位。[1]

An investor can buy a stock and sell it later. If the stock price increases, the investor profits. If it decreases, the investor will incur a loss.  Determining the stock price is complex; it depends on the number of outstanding shares, the size of the company's future profits, and much more. People trade stocks throughout the day. The stock ticker is a report of the price of a certain stock, updated continuously throughout the trading session by the various stock market exchanges. In this lab, you will use the y-finance API to obtain the stock ticker and extract information about the stock. You will then be asked questions about your results.
