If the random walk theory is correct, then is there any way to “beat the market”?

What will be an ideal response?

ANSWER:

If the random walk theory is correct, then no one can use publicly available information to predict the magnitude or direction of a stock price change. However, if you have inside information that is not available to the public, then you can still “beat the market.” Inside information is about what is happening in a corporation that is not available to the public.
