Filing Trend Analysis

Seasonal and Trend decomposition (STL) of SEC filing volumes using Loess smoothing.

Parameters

The dataset contains monthly aggregated counts from 2016 to 2026. Forms require at least 24 months of filings to generate STL decomposition.

Understanding STL

Observed:

The raw counts of filings received per month.

Trend:

The long-term movement, smoothing out seasonal and random variations.

Seasonal:

The regular yearly cycles (e.g. recurring quarterly reporting patterns).

Residual (Noise):

Random fluctuations remaining after trend and seasonality are removed. Red indicates a spike above expectations; blue indicates a drop below.
