Questions about MCK
What people ask.
Why is MCK on Broken Stocks?
MCK qualifies for the Red List on decline depth. It is down -25.2% from its rolling 252-day high of $999.00, set on 2026-03-03 — 72d ago.
Is MCK a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. MCK is down -25.2% 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 MCK 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 MCK trading inside its 52-week range?
At $747.23, MCK sits 8.6% of the way from its 52-week low ($723.68) to its 52-week high ($999.00). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has MCK been declining?
The current 25.2% decline accrued over 72d, which annualizes to roughly -127.8% 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.
