Questions about AMT
What people ask.
Why is AMT on Broken Stocks?
AMT qualifies for the Amber List on decline sigma. The recent drop measures 3.9σ over a 20-bar window — large enough that even a small percentage drop is structurally significant given the stock's typical day-to-day volatility (1.3%).
Is AMT a falling knife?
AMT is on Broken Stocks for time-frame continuity or decline-sigma reasons rather than headline depth, so the falling-knife label doesn't cleanly apply. The phrase usually requires a meaningful percentage drop from a fresh high. See the structural break signals above for the axis that actually triggered the listing.
Is AMT 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 AMT trading inside its 52-week range?
At $172.98, AMT sits 46.2% of the way from its 52-week low ($160.06) to its 52-week high ($188.02). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
