Metric Summary Cards

These cards give a compact readout of the selected series and place the latest value into statistical context.

Current value

$$x_t$$

The latest available data point of the selected series.

Values are displayed in compact form such as K, M, B, and T when appropriate, while still preserving meaningful decimals.

Percentile (4Y) and Zone

$${\mathrm{P}\mathrm{e}\mathrm{r}\mathrm{c}\mathrm{e}\mathrm{n}\mathrm{t}\mathrm{i}\mathrm{l}\mathrm{e}}_{4Y}(x_t)$$

Percentile shows where the current value sits within the last 4 years of daily data, using up to 1460 observations.

If the series is shorter than 4 years, all available history is used instead. If fewer than 90 observations are available, the percentile is hidden.

Zone groups that percentile into broad ranges for faster interpretation:

• Cold — below the 10th percentile
• Cool — 10th to 25th percentile
• Neutral — 25th to 75th percentile
• Warm — 75th to 90th percentile
• Hot — 90th percentile and above

7D change

$${\Delta }_{7D}(\%)=\frac{x_t-x_{t-7}}{x_{t-7}}\times 100$$

90D change

$${\Delta }_{90D}(\%)=\frac{x_t-x_{t-90}}{x_{t-90}}\times 100$$

The line reading from ... (90D ago) shows the actual value from 90 days earlier:

$$x_{t-90}$$

Distance

Shows how far the current value is from the extremes of the same 4-year window used for the percentile. If 4 years of data are not available, full history is used instead.

To 4Y High

$${\mathrm{T}\mathrm{o}\mathrm{H}\mathrm{i}\mathrm{g}\mathrm{h}}_{4Y}(\%)=\frac{x_t-max(x)}{|max(x)|}\times 100$$

Example: −67% to 4Y High means the current value is 67% below the 4-year high.

From 4Y Low

$${\mathrm{F}\mathrm{r}\mathrm{o}\mathrm{m}\mathrm{L}\mathrm{o}\mathrm{w}}_{4Y}(\%)=\frac{x_t-min(x)}{|min(x)|}\times 100$$

Example: +414% from 4Y Low means the current value is 414% above the 4-year low.

z-Score (robust)

$$z_{\mathrm{r}\mathrm{o}\mathrm{b}\mathrm{u}\mathrm{s}\mathrm{t},365D}=\frac{x_t-{\mathrm{m}\mathrm{e}\mathrm{d}\mathrm{i}\mathrm{a}\mathrm{n}}_{365D}}{1.4826\times {\mathrm{M}\mathrm{A}\mathrm{D}}_{365D}}$$

A 365-day robust z-score based on the median and MAD, or Median Absolute Deviation.

The factor 1.4826 rescales MAD so it is comparable to standard deviation under a normal distribution.

The label, such as Normal, Elevated, or Extreme, follows common cutoffs around ±1σ and ±2σ.

Volatility

$${\sigma }_{30D,\mathrm{a}\mathrm{n}\mathrm{n}}=\mathrm{s}\mathrm{t}\mathrm{d}\mathrm{e}\mathrm{v}\left(\ln \left(\frac{v_t}{v_{t-1}}\right)\right)\times \sqrt{365}$$

30-day annualized volatility based on log returns.

This value is only computed for strictly positive series.

Notes

All windows assume daily data.

Missing or non-finite values are skipped. If the series is shorter than a given window, all available data is used instead.
