Story summary

The U.S. stock market faces volatility after potential 100% tariffs on China, described as a “tariff tantrum” by analysts.
On October 10, 2025, the S&P 500 declined sharply, triggering a new McMillan Volatility Band sell signal.
Analysts identify levels between 6,500 and 6,550, and a breach of 6,500 could signal a bearish outlook.
The widening of MVB bands indicates ongoing high volatility, and investors should monitor these indicators.

History

Historical Context

The Smoot-Hawley Tariff Act, signed by President Herbert Hoover on June 17, 1930, raised tariffs on over 20,000 goods to protect U.S. industries during the Great Depression. This protectionist measure led to retaliatory tariffs from trading partners, causing U.S. exports to plummet by 61% from 1929 to 1933 and worsening the economic crisis, serving as a cautionary tale for modern trade policies.
