Historical Volatility (HV) measures how much the price of a security fluctuates over time, indicating the level of risk associated with that asset. It is calculated using the standard deviation of past price changes, helping investors understand the price movement relative to its average.
Weighted Moving Average (WMA) is a statistical calculation that gives more importance to recent data points while averaging, making it more responsive to changes than a simple moving average.

If VIX9D > VIX: Short-term volatility (next 9 days) is expected to be higher than the 30-day average, often signaling near-term market stress or upcoming events.
If VIX9D < VIX: Short-term volatility is expected to be lower, suggesting a calmer near-term market relative to the 30-day outlook.
In statistics, the Percentile Rank (PR) of a given score is the percentage of scores in its frequency distribution that are less than that score.
If the number is smaller than the smallest over the previous year (in this case), the PR is 0%, or if it is larger than the largest over the previous year (in this case), the PR is 100%.
PR of volatility metrics is a good indicator of market risk - see the Cash VIX Term Structure explained by Brent Osachoff. We are using a 1-Year PR here for reference.

Increased volatility in the stock market generally leads to wider price swings, but its effect on stock prices isn't uniform and depends on context. Higher volatility often signals greater uncertainty, which can spook investors, leading to sell-offs and downward pressure on prices, especially for riskier stocks. For example, during market shocks like geopolitical events or economic data surprises, heightened volatility tends to correlate with declining stock prices as fear dominates.
