The prosperity of the market equally fueled the boom in the stock market, and in the face of favorable news, everyone's confidence also reached its peak.
Compared to liquidating physical industries, it's much easier to pull out of the stock market. With buying and selling happening daily, a few percentage points of change are just normal market fluctuations.
It's not a period of economic crisis, so these small fluctuations are completely within the market's capacity to endure, most typically seen in the continued rise of stock prices.
Candidly speaking, speculating in the stock market yields far greater profits than manufacturing. However, with advantages come disadvantages; high returns are also accompanied by high risks.
Without leverage, you can't make much money, but playing with leverage brings immense risks, and oftentimes, a single random fluctuation in the market sweeps away a large number of speculators.
