Information theory stock market
This theory is based on the classical idea of supply and demand as it relates to the stock market. Essentially, this theory proposes that the price of any stock is not affected as much by the Shannon and Thorp also applied the same theory, later known as the Kelly criterion, to the stock market with even better results. Over the decades, Kelly’s scientific formula has become a part of mainstream investment theory and the most prominent users, well-known and successful billionaire investors Warren Buffett , Bill Gross , and Jim Simons use Kelly methods. The EMH states that the market price for shares incorporates all the known information about that stock. This means that the stock is accurately valued until a future event changes that valuation. The Efficient Market Hypothesis, or EMH, is an investment theory whereby share prices reflect all information and consistent alpha generation is impossible. Theoretically, neither technical nor fundamental analysis can produce risk-adjusted excess returns, or alpha, The efficient-market hypothesis 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. Since risk adjustment is central to the EMH, and yet the EMH does not specify a model of risk, the EMH is untestable. As a result, research in financial economics since at least the 1990s has focused o
