Questions about 3905.T
What people ask.
Why is 3905.T on Broken Stocks?
3905.T qualifies for the Red List on decline depth. It is down -73.9% from its rolling 252-day high of 6,140.00 JPY, set on 2026-05-29 — 104d ago.
Is 3905.T a falling knife?
By the most common technical definition — a steep, recent breakdown from a fresh high — yes. 3905.T is down -73.9% from its 52-week high of 6,140.00 JPY, set 104d 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 3905.T 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 3905.T trading inside its 52-week range?
At 1,605.00 JPY, 3905.T sits 6.9% of the way from its 52-week low (1,270.00 JPY) to its 52-week high (6,140.00 JPY). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has 3905.T been declining?
The current 73.9% decline accrued over 104d, which annualizes to roughly -259.4% 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.
