The structural read
What price action says about TAC.
TAC qualifies for the Watch on decline depth — down -21.2% from its rolling 252-day high.
Alongside that decline, our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames — moderate or strong time-frame-continuity (TFC) alignment — so the ticker also carries a Recovering badge. The two readings coexist: the tier tells you how deep the damage is, the Recovering badge tells you whether momentum may be turning. Recovering is not a buy signal; it's a structural read.
Broken Stocks stops here — it flags the structure, it doesn't build the upside case. Working out whether TAC's turn is investable is what our sister tool does: ConvictionEdge — triple-engine conviction research on names showing a recovery signal.
Upstream TFC read: strong alignment, current phase weekly. Last bar types — daily 2U (green), weekly 2U (green), monthly 1 (green).
Earnings on file: 2026-05-06. Tiering is unaffected by earnings dates — listings reflect price structure only.

Questions about TAC
What people ask.
Why is TAC on Broken Stocks?
TAC qualifies for the Watch on decline depth. It is down -21.2% from its rolling 252-day high of $17.81, set on 2025-10-29 — 211d ago. It additionally carries a Recovering badge — see below.
What does the Recovering badge mean for TAC?
Recovering means our proprietary engine has flagged a confirmed bullish structural signal on one or more time frames (moderate or strong time-frame continuity). It coexists with the decline tier — TAC is still Watch because the rolling-252-day decline hasn't healed, but a bullish setup has formed inside that decline. The two readings answer different questions: the tier tells you how deep the damage is; the Recovering badge tells you whether momentum may be turning. It's not a buy recommendation.
Is TAC a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. TAC is down -21.2% 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 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 $14.03, TAC sits 59.6% of the way from its 52-week low ($8.34) 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 21.2% decline accrued over 211d, which annualizes to roughly -36.7% 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 TAC compare to its sector?
There are 10 other Utilities tickers on Broken Stocks: 4 Red, 3 Amber, 3 Watch, with 3 showing recovering structural signals. Median sector decline is -28.9% — 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 (2026-05-06) is shown for reference only — listings can move tier between scans based on closing prices, regardless of fundamentals or news events.
