当日股价是根据多种因素变动的。其中，最重要的因素是公司的财务表现，包括营收、利润、资产负债表等。这些数据能够反映公司的经营状况和盈利能力，从而影响投资者的投资决策和股价的变动。

此外，宏观经济因素也会影响当日股价的变动。例如，利率的升降、通货膨胀率的高低、经济增长速度的快慢等都会影响投资者的风险偏好和投资选择，从而影响股价。

另外，市场供需关系也是影响当日股价的重要因素。如果市场上的投资者对某只股票的需求增加，而供应量不足，则股价就会上涨；反之，如果市场上的供应量过剩，而需求不足，则股价就会下跌。

此外，政治因素、自然灾害、社会事件等也会影响当日股价的变动。例如，政治动荡、自然灾害发生时，投资者可能会将资金投入到更加稳定的投资品种中，从而影响相关公司的股价。

总的来说，当日股价的变动是由多种因素共同作用的结果。这些因素包括公司的财务表现、宏观经济因素、市场供需关系以及政治、自然灾害、社会事件等其他因素。这些因素的变化是不可预测的，因此投资者在进行投资决策时需要全面考虑各种因素的风险和收益，进行理性投资。

The daily stock price is influenced by various factors. The most important factor is the company's financial performance, including revenue, profit, balance sheet, etc. These data can reflect the company's operating conditions and profitability, thereby affecting investors' investment decisions and stock price fluctuations.

In addition, macroeconomic factors will also affect the daily stock price. For example, changes in interest rates, inflation rates, economic growth rates, etc. will affect investors' risk preferences and investment choices, thus affecting stock prices.

In addition, market supply and demand are also important factors affecting the daily stock price. If the market demand for a stock increases and the supply is insufficient, the stock price will rise; conversely, if the market supply is excessive and the demand is insufficient, the stock price will fall.

In addition, political factors, natural disasters, social events, etc. will also affect the daily stock price fluctuations. For example, during political unrest or natural disasters, investors may invest funds in more stable investment varieties, thereby affecting the stock prices of related companies.

Overall, the daily stock price fluctuations are the result of various factors acting together. These factors include the company's financial performance, macroeconomic factors, market supply and demand, as well as other factors such as politics, natural disasters, and social events. The changes in these factors are unpredictable, so investors need to comprehensively consider the risks and returns of various factors when making investment decisions and make rational investments.
