Methodology
- Universe. The four most-cited U.S. equity benchmarks: NASDAQ Composite (^IXIC), S&P 500 (^GSPC), Dow Jones Industrial Average (^DJI), and Russell 2000 (^RUT).
- Window. Twelve calendar months ending on the most recent trading day.
- Filter. Only sessions whose calendar weekday is Tuesday are counted. If a Tuesday is a market holiday the data source omits that row (it is not double-counted on any other day).
- Color rule. A Tuesday is "green" if its closing print is strictly greater than the prior trading day's close, "red" if strictly less. Closes equal to the prior session are counted as flat (none in this window).
- Source. Yahoo Finance daily OHLC, fetched via the
yfinance Python library. Closes are unadjusted (raw exchange-published values).
- Not investment advice. Historical patterns do not predict future returns. This report is presented as a descriptive statistic, not a trading signal.
