JPMorgan Chase & Co.‘s (NYSE:JPM) CEO Jamie Dimon voiced his apprehensions about the current market enthusiasm and the state of the economy.

Speaking at the Bernstein Strategic Decisions Conference in New York on Wednesday, Dimon characterized the prevailing market sentiment among Wall Street clients as “gung ho,” suggesting a high degree of optimism and confidence, reported Yahoo Finance.

However, Dimon also highlighted that similar instances of market “exuberance” were seen before significant market crashes in the past.

“Right now, it’s good, but it was in ‘72, ‘86, 2000, 2007,” he remarked, implying potential risks in the current market scenario.

“That doesn’t give me comfort,” he added.
