If WW1 did not happen, would the Great Depression still occur?

As per the title. From my understanding, The Great Depression was partly caused by gold flowing from Europe to the US during WW1 and the US selling a lot of goods to the Allies. When the war ended that demand decreased and there was a lot of speculation in the Stock Market.

Without some of these factors, would it still occur? If not, what factors would make it occur if WW1 did not happen?
