Methodology
Each trading day we pair TSLA’s price and volume action with same-day news coverage, earnings events, analyst actions, and sector context, then generate a sourced explanation using AI with live search grounding.

Moves are flagged significant based on their size relative to the stock’s typical daily range. Explanations describe what plausibly drove a move; markets don’t always have a single clean cause.
