The Stock Market Crash of 1929 can be attributed to multiple factors, including:
- Buying stock on margin (on credit): Many investors purchased stocks with borrowed money, which increased the buying frenzy and led to inflated stock prices that were unsustainable.
- Stock prices did not equal the value of the company: Many stocks were overvalued, with prices not reflecting the underlying value or performance of the companies.
While the huge purchase of consumer durables contributed to the economic activity of the late 1920s, the primary causes of the crash were more related to speculative investment practices and inflation of stock prices.
Given these points, the correct answer would be:
A, B, and C.
