英文翻译对照：Why do some stock prices fluctuate?

Firstly, the performance of a company is one of the main factors that affect the price of its stock. If a company's profits increase or its revenue grows, its stock price is likely to rise. Conversely, if a company's financial results are poor or its outlook worsens, its stock price is likely to decline.

Secondly, economic conditions are another factor that affects stock prices. For example, if the economy is experiencing high unemployment or low inflation, investors may be more risk-averse and avoid stocks that are more volatile or speculative. This could lead to a decrease in stock prices. Conversely, if the economy is growing and inflation is rising, investors may be more willing to take risks and invest in more volatile stocks, leading to an increase in stock prices.

Thirdly, market sentiment can also affect stock prices. Market sentiment refers to the overall mood or sentiment of investors towards the market. If investors are optimistic about the market's prospects, they may be more willing to buy stocks, leading to an increase in stock prices. Conversely, if investors are pessimistic about the market's prospects, they may be less willing to buy stocks, leading to a decrease in stock prices.

Finally, other factors can also affect stock prices, such as political events, natural disasters, and regulatory changes. For example, if a country experiences a political crisis or an earthquake, its stock prices are likely to decline. Conversely, if a country passes a law that is beneficial to a particular industry, the stocks of companies in that industry are likely to rise.

In conclusion, the price of a stock is affected by many factors, including the performance of the company, economic conditions, market sentiment, and other external factors. Therefore, stock prices can be volatile and investors need to carefully consider all relevant factors before investing.
