Questions about ON

What people ask.

Why is ON on Broken Stocks?

ON qualifies for the Red List on decline depth. It is down -44.6% from its rolling 252-day high of $134.92, set on 2026-06-03 — 78d ago.

Is ON a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. ON is down -44.6% from its 52-week high of $134.92, set 78d ago. That combination of depth (past the 30% Amber threshold) and recency (high set inside the last 120 days) is the textbook falling-knife pattern. Whether to try to catch it is a separate question — historically most attempts to bottom-pick continue lower before reversing. Broken Stocks flags the pattern; it does not recommend buying or selling.

Is ON a buy?

Broken Stocks does not issue buy or sell recommendations. The list is a rules-based technical warning system. It tracks structural decline depth and recency — not company quality, management, fundamentals, or news. Always do your own research and consult a licensed advisor.

Where is ON trading inside its 52-week range?

At $74.71, ON sits 33.4% of the way from its 52-week low ($44.56) to its 52-week high ($134.92). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has ON been declining?

The current 44.6% decline accrued over 78d, which annualizes to roughly -208.7% per year. Annualized pace is a sanity check — a 30% decline in three months is a different signal than a 30% decline over two years.

How does ON compare to its sector?

There are 239 other Technology tickers on Broken Stocks: 147 Red, 50 Amber, 42 Watch, with 65 showing recovering structural signals. Median sector decline is -36.7% — ON's decline is deeper than the sector median.

Does ON's earnings date affect its tier?

No. Tiering is decided purely by decline depth and recency of the rolling-high date. The earnings date on file (2026-08-03) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
