06 Dec, 2025
A » Market efficiency is categorized into three forms: weak, semi-strong, and strong. Weak form asserts that past price movements and volume data do not predict future prices. Semi-strong form suggests that all publicly available information is reflected in stock prices, rendering fundamental analysis ineffective. Strong form posits that all information, public and private, is fully integrated into stock prices, making it impossible to achieve consistent excess returns.
