The 20-minute mandatory suspension is not merely a trading halt, <u>An opportunity to calmly analyze why the market has plummeted like this.<\/u>It provides... Investors should use this time to determine whether the cause of the decline is due to temporary fear or structural economic problems.<\/p>\n<p>It is also important to note that circuit breakers are rarely triggered. The one triggered in early March 2026 was the first in one year and seven months, and it was a decline caused by external shocks, such as a surge in international oil prices due to geopolitical conflicts in the Middle East. As such, shocks caused by macroeconomic external factors can actually present an opportunity for long-term investors to enter positions.
