Do stock prices reflect all historical data about companies?
True.
The efficient market hypothesis (EMH) or theory states that share prices reflect all information. The EMH hypothesizes that stocks trade at their fair market value on exchanges. Proponents of EMH posit that investors benefit from investing in a low-cost, passive portfolio.
The efficient-market hypothesis (EMH) is a hypothesis in financial economics that states that asset prices reflect all available information. A direct implication is that it is impossible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information.
Fama (1970): “A market in which prices always 'fully reflect' available information is called 'efficient'.”
A company's stock price reflects investor perception of its ability to earn and grow its profits in the future. If shareholders are happy and the company is doing well, as reflected by its share price, its executives are likely to keep their jobs and receive increases in compensation.
Stocks' market prices reflect these fundamental values to varying degrees. When those prices are closer to fundamental values, they are said to have a higher degree of accuracy. Conversely, when they are farther from those values, they are said to have a lower degree of accuracy.
Price-to-earnings ratio (P/E): Calculated by dividing the current price of a stock by its EPS, the P/E ratio is a commonly quoted measure of stock value. In a nutshell, P/E tells you how much investors are paying for a dollar of a company's earnings.
Efficient capital markets are commonly thought of as markets in which security prices fully reflect all relevant information that is available about the fundamental value of the securities.
Closing stock is always valued at cost price or market price whichever is less. It is based on the principle of Conservatism.
On a given day, the price of a company's stock doesn't matter to it operationally, unless it's trying to buy or sell its shares that day. Generally, Corporations do not “gain money” when the price of shares of stock in the corporation increases. Or lose money when the price drops.
Why is it hard to predict stock prices?
Complexity — The stock market is an extremely complex system with countless variables that interact and influence prices. These include macroeconomic factors such as economic growth, interest rates, political events, natural disasters, consumer sentiment, corporate earnings, etc.
Stock prices are driven by a variety of factors, but ultimately the price at any given moment is due to the supply and demand at that point in time in the market.
What determines stock prices? The price of a stock is largely determined by supply and demand. If demand is high, the price tends to go up, and if supply is high, the price tends to go down.
A bull market is the condition of a financial market in which prices are rising or are expected to rise. The term "bull market" is most often used to refer to the stock market but can be applied to anything that is traded, such as bonds, real estate, currencies, and commodities.
Random walk theory suggests that changes in asset prices are random. This means that stock prices move unpredictably, so that past prices cannot be used to accurately predict future prices. Random walk theory also implies that the stock market is efficient and reflects all available information.
Another study analyzed a dataset consisting of 6,627 forecasts made by 68 forecasters. It found that while some forecasters did “very well,” the “majority perform at levels not significantly different than chance.” Overall, only 48% of forecasts were correct.
The stock market's movements can impact companies in a variety of ways. The rise and fall of share price values affects a company's market capitalization and therefore its market value. The higher shares are priced, the more a company is worth in market value and vice versa.
The reason behind this is that analysts base their future value of a company on their earnings projection. If a company's results surprise (are better than expected), the price jumps up. If a company's results disappoint (are worse than expected), then the price will fall.

The Buffett Indicator is the ratio of total US stock market value divided by GDP. Named after Warren Buffett, who called the ratio "the best single measure of where valuations stand at any given moment".
Key Takeaways. In picking stocks, Warren Buffett looks for companies that have provided a good return on equity over many years, particularly when compared to rival companies in the same industry. Buffett also reviews a company's profit margins to ensure they are healthy and growing.
An inefficient market is one that does not succeed in incorporating all available information into a true reflection of an asset's fair price. Market inefficiencies exist due to information asymmetries, transaction costs, market psychology, and human emotion, among other reasons.
Market efficiency refers to the degree to which market prices reflect all available, relevant information. If markets are efficient, then all information is already incorporated into prices, and so there is no way to "beat" the market because there are no undervalued or overvalued securities available.
