Questions about ERII
What people ask.
Why is ERII on Broken Stocks?
ERII qualifies for the Red List on decline depth. It is down -53.0% from its rolling 252-day high of $18.32, set on 2025-10-27 — 199d ago.
Is ERII a falling knife?
Not by the strict technical definition. ERII is down -53.0% from its 52-week high, but that high was set 199d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. ERII is still on the Red List for decline depth, but the freshness component of a falling knife is missing.
Is ERII 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 ERII trading inside its 52-week range?
At $8.62, ERII sits 0.0% of the way from its 52-week low ($9.35) to its 52-week high ($18.32). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has ERII been declining?
The current 53.0% decline accrued over 199d, which annualizes to roughly -97.2% 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 ERII compare to its sector?
There are 119 other Industrials tickers on Broken Stocks: 60 Red, 22 Amber, 37 Watch, with 23 showing recovering structural signals. Median sector decline is -32.5% — ERII's decline is deeper than the sector median.
Does ERII'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 (2026-02-25) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
