The efficient markets hypothesis (EMH) is indeed a broader theory that includes the random walk hypothesis, suggesting that asset prices fully reflect all available information. Most empirical studies support the EMH to some extent, though it is challenged by observed market anomalies such as the "January effect," where stocks have historically shown higher returns in January than in other months.
