Trading Days in Each Month Across The Years

This table provides a historical record of trading days per month for each year, offering a clear view of market activity over time. It helps identify seasonal fluctuations, market closures, and variations in trading schedules that may impact investment decisions. By analyzing this data, traders and analysts can spot trends such as months with fewer trading days due to holidays or regulatory changes and assess how these variations might influence liquidity, volatility, and overall market behavior throughout the years. This information is particularly useful for traders planning investment strategies, financial professionals analyzing market cycles, and researchers studying long-term trading patterns.

Annual Summary Table of Trading Activities

This table provides a comprehensive yearly overview of trading activity, highlighting key metrics such as trading days, price fluctuations, and market trends. It includes the first and last trading days of each year, total trading days, and price movements, including the highest and lowest prices, opening and closing values. By analyzing this data, traders and analysts can track historical price patterns, assess market volatility, and gain insights into yearly stock performance to support strategic investment decisions.

Monthly Cumulative Percent Change by Year

Each cell shows the sum of daily intraday percent changes within that month for the given year. Each day contributes its open-to-close move as a percentage — overnight gaps between sessions are excluded. A positive value means the stock consistently gained ground during trading hours that month; negative means it lost ground during market hours. Compared to the Absolute Return table, which measures the single open-to-close move across the entire month, this table reveals how that return was built day by day — and whether it came from steady intraday buying pressure or was concentrated in just a few sessions.

Monthly Seasonality — Cumulative Daily Returns (%)

Each cell shows the sum of all daily percent changes within that month for the given year. This is the arithmetic cumulative return — the same methodology used in the seasonality charts above. A positive value means the stock gained ground across its trading days that month; negative means it lost ground. Colors reflect relative magnitude within each month across all years.

Monthly Absolute Percent Change by Year

Each cell shows the actual percent change from the first trading day’s opening price to the last trading day’s closing price of that month. This represents the total return an investor would have experienced entering at the open on the first trading day and exiting at the close on the last trading day.

Monthly Seasonality — Absolute Price Return (%)

Each cell shows the actual percent change from the first trading day's close to the last trading day's close of that month. This is the true price return an investor would have experienced holding the stock for the entire month. While similar to the cumulative table, small differences arise because the cumulative method sums daily changes arithmetically rather than compounding them.

Seasonality: Trading Day of the Month

Trading Day Index Method 3 of 3

This analysis assigns each trading day within a month a sequential index — trading day 1 is the first market-open day of the month, day 2 the second, and so on regardless of calendar date. Most months have 19–23 trading days. By aligning all months across all years to this index, recurring patterns at the start or end of the trading month become visible — such as consistent strength in the first few days or weakness in the final stretch.

Each line represents a year, showing how cumulative percent change in closing price builds across trading days 1 through 23 within a month. The average line highlights the typical intra-month pattern across all years.
