How does Bitcoin compare with traditional markets?
This tool compares Bitcoin's relative performance against the S&P 500, gold and crude oil (WTI) over the last year. Every series is rebased to 100 at the start of the window, so you can see who has gained or lost more, regardless of their price in dollars.
It also shows the correlation of Bitcoin's daily returns with each market and with the VIX (the stock-market "fear index"). A value near +1 means they move together; near −1, in opposite directions; near 0, no linear relationship.
This is descriptive market data, not investment advice.
What does "rebased to 100" mean?
Each asset starts at 100 on the first day of the window; every later point is its price relative to that start. So a value of 130 means +30% since the start. It lets you compare assets with very different prices on the same scale.
What is correlation and how do I read it?
It measures how two assets' daily returns move together, from −1 to +1. Near +1 they tend to rise and fall together; near −1 they move oppositely; near 0 there is no consistent linear link. It is a statistical fact over the period shown, not a prediction.
Why include the VIX?
The VIX gauges expected stock-market volatility (the "fear index"). Watching how BTC correlates with it helps describe whether Bitcoin has behaved like a risk asset or independently during stress periods. We only describe the figure.
Where does the data come from?
Daily closing prices come from Yahoo Finance (no API key) for BTC-USD, the S&P 500, gold and WTI futures, and the VIX. Everything is computed live over common trading days; nothing is stored.
