1. How much did the Dow Jones index fall?

Dow refers to the American Dow Jones index, which is the arithmetic average stock price index compiled by Charles Henry Dow, the founder of Dow Jones Company, in 1884. The index includes the largest and most famous listed companies in the United States in the past 30 years, and it is also one of the oldest and most credible stock indexes in the world.

However, the benchmark index of the US stock fuse mechanism is the S&P 500 index, not the Dow Jones Industrial Average. For example, the fourth fuse of US stocks was triggered after the S&P 500 index fell at 9: 30 am on March 16.

Second, the US stock fuse rules

1987101October19, the Dow Jones index plunged 508 points, and the fuse mechanism, which set a record for the daily decline of US stocks, was officially implemented the following year. At the beginning, it was also based on the benchmark index of the Dow Jones Industrial Average. The trigger of the fuse mechanism was based on the number of points in the market decline rather than the percentage.

1997101On October 27th, the Dow Jones Industrial Average plummeted, triggering the first fuse in the history of US stocks. Subsequently, the fuse mechanism was adjusted to three fuse thresholds of 10%, 20% and 30%, and it was officially implemented in April of 1998.

On May 3, 2002, the NYSE revised the index fuse mechanism again. This time, it not only adjusted the fuse threshold, but also used the S&P 500 index instead of the Dow Jones Industrial Average as the fuse benchmark index.

Therefore, the fuse of the US stock market is based on the S&P 500 index, not the Dow Jones index. The fusing thresholds of S&P 500 index are 7%, 13% and 20% respectively.

The above content about how much the Dow has fallen and how much it has melted, I hope it will help everyone. Warm reminder, financial management is risky and investment needs to be cautious.
