One Wall Street measure of market fragility just hit its highest possible level. The last time it did, volatility spiked.

The market turbulence indicator, a key Wall Street gauge of market fragility, reached its maximum level of 1 on August 19, marking the first time since December 2024 post-election. This spike suggests heightened investor anxiety and potential for increased volatility. Historically, similar readings have preceded significant market volatility, indicating investors should brace for potential turbulence ahead. This level of fragility underscores the impact of broader economic and political uncertainties on market stability.
