After inserting N tickers and choosing a time period, this app displays a
correlation matrix (N×N) showing how closely each asset's returns moved together
over that window. A table of relevant metrics is included alongside —
beta, market cap, trailing/forward price-to-earnings ratios, and upcoming earnings date.
Interactive time series charts for each ticker show historical price along with
simple and exponential moving averages and Bollinger Bands. On mobile,
landscape mode makes these easier to visualize and manipulate.
