What price action says about TTEK.

TTEK qualifies for the Red List on decline depth — down -39.2% from its rolling 252-day high. Past 30% with the high set inside the last four months — the recency clause that often precedes further breakdown. Depth plus recency: this is the pattern many investors call a falling knife.

Questions about TTEK

What people ask.

Why is TTEK on Broken Stocks?

TTEK qualifies for the Red List on decline depth. It is down -39.2% from its rolling 252-day high of $43.07, set on 2026-02-11 — 92d ago.

Is TTEK a falling knife?

By the most common technical definition — a steep, recent breakdown from a fresh high — yes. TTEK is down -39.2% from its 52-week high of $43.07, set 92d 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 TTEK 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 TTEK trading inside its 52-week range?

At $26.20, TTEK sits 0.0% of the way from its 52-week low ($29.56) to its 52-week high ($43.14). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has TTEK been declining?

The current 39.2% decline accrued over 92d, which annualizes to roughly -155.5% 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 TTEK 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% — TTEK's decline is deeper than the sector median.

Does TTEK'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 (2026-04-29) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
