Questions about TAC
What people ask.
Why is TAC on Broken Stocks?
TAC qualifies for the Amber List on decline depth. It is down -33.1% from its rolling 252-day high of $17.88, set on 2025-10-29 — 316d ago.
Is TAC a falling knife?
Not by the strict technical definition. TAC is down -33.1% from its 52-week high, but that high was set 316d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. TAC is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is TAC 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 TAC trading inside its 52-week range?
At $12.18, TAC sits 12.3% of the way from its 52-week low ($11.38) to its 52-week high ($17.88). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has TAC been declining?
The current 33.1% decline accrued over 316d, which annualizes to roughly -38.2% 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 TAC compare to its sector?
There are 35 other Utilities tickers on Broken Stocks: 21 Red, 9 Amber, 5 Watch, with 2 showing recovering structural signals. Median sector decline is -37.8% — TAC's decline is shallower than the sector median.
Does TAC'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 (2026-07-31) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
