How did buying stock on margin increase the bull market?

Buying stock on margin allowed investors to purchase more shares than they could with their available cash, effectively amplifying their potential gains. This practice led to increased demand for stocks, driving prices higher and contributing to the overall optimism of the bull market. As prices rose, more investors were encouraged to enter the market, further fueling the bullish trend. However, this also increased risk, as a market downturn could lead to significant losses for those using margin.
