Questions about LRCX
What people ask.
Why is LRCX on Broken Stocks?
LRCX qualifies for the Watch on decline sigma. The recent drop measures 4.3σ over a 5-bar window — large enough that even a small percentage drop is structurally significant given the stock's typical day-to-day volatility (6.62%).
Is LRCX a falling knife?
LRCX 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 LRCX 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 LRCX trading inside its 52-week range?
At $326.13, LRCX sits 42.9% of the way from its 52-week low ($241.60) to its 52-week high ($438.50). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
