A stock split changes the number of shares while adjusting the per-share price proportionally. In a 1:10 split, one $1,000 share becomes ten $100 shares, leaving the position’s nominal value unchanged. section 3.4.2
Because per-share prices alone are not comparable, normalize each stock to 100% at a chosen starting date before comparing performance. This avoids confusing a high nominal price with stronger returns. section 3.4.2
Comparing split-affected prices
Track Apple, Coca-Cola, and NuScale from the same starting point, then plot each closing-price series as a percentage of its initial value. The resulting chart supports comparison across different share counts and price levels, but a favorable historical comparison does not guarantee future performance. section 3.4.2
