What This Does
This platform converts financial asset prices — stocks, ETFs, and major indexes — from US dollars into real commodity units. Instead of asking "how many dollars is the S&P 500 worth?", it asks "how many ounces of gold is the S&P 500 worth?" The answer often tells a very different story.
The conversion is straightforward: asset_price_USD ÷ commodity_price_USD = asset_price_in_commodity_units. But the insight it provides is profound — it removes the variable of currency debasement from the equation entirely.

How the conversion works
The calculation is a simple division: the closing price of the asset in USD is divided by the closing price of the commodity in USD on the same date. The result is the number of commodity units the asset could theoretically purchase on that date.
For dates where commodity price data is unavailable (weekends, holidays), the platform interpolates using the nearest available prices so the time series remains continuous. This approach is transparent and reproducible from publicly available Yahoo Finance data.
For example: if the Dow Jones closes at $38,000 and gold closes at $2,500/oz on the same day, the Dow is worth 38,000 ÷ 2,500 = 15.2 troy ounces of gold.
