Questions about TDC

What people ask.

Why is TDC on Broken Stocks?

TDC qualifies for the Amber List on decline depth. It is down -34.5% from its rolling 252-day high of $41.78, set on 2026-02-11 — 211d ago.

Is TDC a falling knife?

Not by the strict technical definition. TDC is down -34.5% from its 52-week high, but that high was set 211d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. TDC is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.

Is TDC 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 TDC trading inside its 52-week range?

At $27.36, TDC sits 33.9% of the way from its 52-week low ($19.96) to its 52-week high ($41.78). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.

How fast has TDC been declining?

The current 34.5% decline accrued over 211d, which annualizes to roughly -59.7% 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 TDC compare to its sector?

There are 455 other Technology tickers on Broken Stocks: 309 Red, 91 Amber, 55 Watch, with 49 showing recovering structural signals. Median sector decline is -40.8% — TDC's decline is shallower than the sector median.

Does TDC'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 (2026-08-04) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
