Questions about 4526.TW
What people ask.
Why is 4526.TW on Broken Stocks?
4526.TW qualifies for the Watch on decline depth. It is down -29.6% from its rolling 252-day high of 44.62 TWD, set on 2026-06-04 — 106d ago.
Is 4526.TW a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. 4526.TW is down -29.6% 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 4526.TW 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 4526.TW trading inside its 52-week range?
At 31.25 TWD, 4526.TW sits 28.8% of the way from its 52-week low (25.15 TWD) to its 52-week high (46.30 TWD). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has 4526.TW been declining?
The current 29.6% decline accrued over 106d, which annualizes to roughly -101.9% 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.

There are 524 other Industrials tickers on Broken Stocks: 295 Red, 119 Amber, 110 Watch, with 252 showing recovering structural signals. Median sector decline is -35.6% — 4526.TW's decline is shallower than the sector median.
