"A big tech stock reckoning and correction is inevitable," the chief investment officer told CNBC's " Street Signs Asia " on Tuesday. Calling the euphoria around Big Tech stocks this year "absurd," he said that such excessive investor sentiment and "overdone" momentum "always ends the same." "The biggest risk for the stock market right now is excessive valuations. Such sectors include health care, consumer staples, utilities, and the midstream part of the energy sector, according to him. "The consumers staples sector is being overlooked right now in the market as investors chase returns in the tech sector," he added.
