Answer:
Step-by-step explanation:
This document is a passage from the book "A History of the American People" by Harry J. Carman and Harold 0. Syrett, published in 1952. The passage describes how margin requirements allowed investors to enter the stock market with only a fraction of the quoted price of any particular security. The additional money needed to cover the purchase was supplied by the broker, who obtained these funds from a bank with which he had deposited his customer's stock as collateral. The margin buyer was particularly vulnerable to even a small decline in stock quotations. With any decrease in security values, he would have to pay the additional money to cover the corresponding decrease in his collateral. If he should be unable to supply this money - and usually he could not - the broker would be compelled to sell the stock to protect himself at the bank. Once this process had started there was always the danger that it could not be stopped. Prices would be further depressed, and more margin buyers would be compelled to dump more stocks on the market .
This document relates to the causes of the Great Depression because it describes how margin requirements allowed investors to enter the stock market with only a fraction of the quoted price of any particular security. This led to an increase in speculation and overvalued stocks, which eventually led to a stock market crash in 1929 and contributed to the onset of the Great Depression .
This document is a secondary source because it is an interpretation of historical events based on primary sources such as newspapers, government documents, and personal accounts .
