News Annotations on the Chart: Tying Headlines to the Tape

Why News on the Chart Matters

Reviewing a stock chart in isolation is almost always misleading. Any big move had a cause — earnings, guidance, an M&A rumor, a product recall, a rating change — and if you can't see the cause alongside the effect, your mental model of why the stock moves when it moves becomes superstitious. News-annotated charts solve this by sticking material headlines at the exact timestamp they were published, with the ability to expand any annotation for the full story.

What the Chart News Card Shows

The Chart News card overlays the price chart with annotation markers at material news events. "Material" is defined by a combination of sentiment magnitude, multi-source coverage, and post-event price move — a press release buried in an SEC filing won't appear, an earnings beat covered by 30 outlets will. Hovering on a marker shows the headline and publication; clicking expands the full story. Filter dropdowns let you limit to earnings, M&A, regulatory, or analyst-related news only.

Using News Annotations Well

Three practices get the most from this view. First, review the chart post-mortem after every trade — a win annotated with a catalyst teaches you more than a win without context; a loss annotated with a missed headline teaches you what you didn't know. Second, check the chart before long holds — a name approaching an anniversary of a material bad news event often shows up as a recurring technical weakness; it's useful to know *why* before you size in. Third, compare cluster density to regime — periods with many headlines usually coincide with high-volatility regimes; the chart helps you sanity-check Market Regime against the underlying information environment.
