VIX deviation from seasonal trend

Dean Christians
2025-08-27

With Nvidia's earnings due after the close today, an event that will almost certainly inject some volatility depending on the outcome, I wanted to share the seasonal chart of the Volatility Index (VIX), which continues to diverge from its typical pattern. 

Although Nvidia could ignite some sparks, I suspect the real trigger for the VIX to align with its seasonal pattern could be a September letdown from the Fed.

When the VIX finished below 15 with just a handful of sessions left in August, the S&P 500 often stumbled in the following months. Still, those setbacks proved temporary, as the index rebounded in nearly every instance, rallying over the next four months all but once.

Interestingly, the most recent examples came in 2023 and 2024, producing maximum losses of 8.5% and 4.2%.

Users should conduct their own due diligence and consider their individual circumstances before making any financial decisions. Past performance is not necessarily indicative of future results.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
