Monthly Returns Tracking

Builds a month by month return table from historical prices. The first trading day of each month is resolved with a dedicated formula, closing prices are pulled for those dates, and returns are computed between consecutive months for as many years as you extend the grid. Rows by year and columns by month make seasonality and clusters of weak months visible in a way a single line chart does not. One ticker per sheet keeps the layout readable, and copying the tab for another symbol reproduces the entire calculation.
