Questions about TDG

What people ask.

Why is TDG on Broken Stocks?

TDG qualifies for the Red List on decline depth. It is down -22.4% from its rolling 252-day high of $1,519.36, set on 2025-07-30 — 288d ago.

Is TDG a falling knife?

No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. TDG is down -22.4% 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 TDG 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 TDG trading inside its 52-week range?

At $1,178.82, TDG sits 11.0% of the way from its 52-week low ($1,123.61) to its 52-week high ($1,623.83). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has TDG been declining?

The current 22.4% decline accrued over 288d, which annualizes to roughly -28.4% 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.

How does TDG 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 -32.6% — TDG's decline is shallower than the sector median.

Does TDG'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 (2026-05-05) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
