Please help me understand these three questions

The concept of market efficiency underpins almost all financial theory and decision models. When financial markets are efficient, the price of a securitysuch as a share of a particular corporation's common stockshould be the present value estimate of the firm's expected cash flows discounted by its appropriate rate of return (also called the intrinsic value of the stock). Almost all financial theory and decision models assume that the financial markets are efficient. The informational efciency of financial markets determines the ability of investors to "beat" the market and earn excess (or abnormal) returns on their investments. If the markets are efficient, they will react rapidly as new relevant information becomes available. Financial theorists have identified three levels of informational efficiency that reflect what information is incorporated in stock prices. Consider the following statement, and identify the form of capital market efficiency under the efficient market hypothesis based on this statement: Current market prices reflect all relevant publicly available information. This statement is consistent with: O Weakform efficiency 0 Strong-form efficiency 0 Semistrong-form efficiency Consider that there is a strongform of efficiency in the markets. A pharmaceutical company announces that it has received Federal Drug Administration approval for a new allergy drug that completely prevents hay fever. The consensus analyst forecast for the company's earnings per share (EPS) is $5.00, and insiders agree with analyst expectations. They too expect that, with this new drug, earnings will drive the EPS to $5.00. What will happen when the company releases its next earnings report? 0 The stock price will not change, because the market already incorporated that information in the stock price when the announcement about FDA approval was made. 0 The stock price will increase and settle at a new equilibrium level. 0 There will be some volatility in the stack price when the earnings report is released; it is difficult to determine the impact on the st0ck price
