Which of the following is(are) used to develop a stock's intrinsic value?

A) Fundamental analysis
B) Assumptions about future cash flows
C) Technical analysis
D) Both a and b

Fundamental analysis is used to evaluate a company's financial information and other qualitative factors to determine an intrinsic value of a stock. Assumptions about future cash flows are also taken into account while evaluating the intrinsic value. Technical analysis is not used to evaluate the intrinsic value of a stock. Therefore, options A and B are correct while C is incorrect, making option D the correct choice. Option E is incorrect as technical analysis is not used for developing intrinsic value.
