The sources of weakness during Herbert Hoover's presidency was the investigators speculating in an unregulated stock market.
Explanation:
Herbert Hoover was the US president during the Great Depression. Even though the blame of Great Depression cannot be put on his policies, his strategies adopted to tackle Great depression failed pathetically. He believed that businesses deciding to not cut down the wages of workers would stop consumption rates from falling down and stabilize the economy.
But this did not happen. Businesses did not cut down wages but they reduced the number of employees to sustain in the falling economic environment. Hoover tried to convince people that there was nothing seriously wrong and when the economy stabilizes stock prices would rise, unemployment would be alleviated and good times would come.
But the optimism did not help the economy and the investors speculating in an unregulated stock market was one of the sources of weakness during Herbert hoover's presidency.
