Questions about MPWR

What people ask.

Why is MPWR on Broken Stocks?

MPWR qualifies for the Amber List on decline depth. It is down -29.7% from its rolling 252-day high of $1,711.48, set on 2026-05-26 — 106d ago.

Is MPWR a falling knife?

No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. MPWR is down -29.7% from its 52-week high, which qualifies for the Watch tier but is shallower than the falling-knife pattern. It's an early-stage decline rather than a sharp breakdown.

Is MPWR 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 MPWR trading inside its 52-week range?

At $1,203.75, MPWR sits 44.1% of the way from its 52-week low ($800.97) to its 52-week high ($1,714.09). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has MPWR been declining?

The current 29.7% decline accrued over 106d, which annualizes to roughly -102.3% 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 MPWR compare to its sector?

There are 453 other Technology tickers on Broken Stocks: 294 Red, 94 Amber, 65 Watch, with 52 showing recovering structural signals. Median sector decline is -39.7% — MPWR's decline is shallower than the sector median.

Does MPWR'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 (2026-07-30) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
