How tips actually work in a efficient market --
Here I am giving my view point on how the tips work.
Assumptions -- market is efficient, the market firmly believes in the analyst who is giving the tip and investors act on the basis on this tip .
Suppose an analyst on the basis of his analysis gives a tip that that a particular share is fundamentally strong, its prices would rise and the investors should invest in that share and than on the basis on the above assuptions the investors actually start investing in that share leading to a increase in its prices -- which would further drive up the prices and this would become a self-fulfilling prophesy and his tip would actually lead to its self-fulfillment .
please refute the above argument
