Multi-Line for Stock Price Comparison — Normalized Equity Index Return
A normalized stock comparison multi-line chart rebases multiple asset price series to a common starting index ($I_0 = 100,\; I_t = 100 \times P_t / P_0$) to compare relative total return and alpha.

How Values Are Scaled
Rebased Index: I_{t,k} = 100 * (P_{t,k} / P_{0,k}). Cumulative Return % = I_{t,k} - 100. Cumulative Alpha = I_{n,A} - I_{n,Benchmark}.

Chart Design & Use-Case Tips
- 01Rebased Index: I_{t,k} = 100 * (P_{t,k} / P_{0,k}). Cumulative Return % = I_{t,k} - 100. Cumulative Alpha = I_{n,A} - I_{n,Benchmark}.
- 02Never plot a $900 stock and a $45 stock on the same raw dollar axis; rebase both to 100 at T0 (`100 * Price_t / Price_0`) so an index reading of 174 immediately means +74% cumulative return.
- 03The vertical gap between Series A and Series B at the final period equals cumulative relative outperformance (alpha).
- 04Use the Braun Monochrome or Architectural Standard palette for institutional investor letters.
Frequently Asked Questions
How do I rebase stock prices to 100?+
Divide each period's price by the starting price and multiply by 100. That way, all assets start at the exact same point (100) on the left axis.
Can I enter cumulative percentage returns (0%, +12%, +26%) instead of Base 100?+
Yes, starting at 0 and entering percentage returns (including negative drawdowns like -8%) works seamlessly as well.
Can I export this for a quarterly fund fact sheet?+
Yes, use the 300-DPI PNG or Vector SVG export to embed in quarterly LP letters.
