See what's inside SPY and QQQ

The full constituents of the S&P 500 and the Nasdaq 100 — weights, sectors, and market breadth — dropped into a formatted Excel sheet and refreshed every night, ready to read the moment you open it.

The Nasdaq 100 (QQQ) gets the identical treatment:

The whole index, drillable

·Every constituent, sorted by weight, with company, sector, and sub-industry.

·Above-SMA breadth glyphs per name across six windows (5 / 10 / 20 / 50 / 100 / 200 day), with the percentage above each.

·Sector → sub-industry → stock drill-down, so you can open any slice of the index.

·Concentration stats — top-5 / 10 / 25 weight, effective number of stocks, and the dominant sector.

·A market-breadth chart — the share of the index above its moving average over time, with an oversold / overbought read.

·Copy Tickers — grab the whole list, or any drilled slice, for a batch backtest.
