Questions about PTC
What people ask.
Why is PTC on Broken Stocks?
PTC qualifies for the Amber List on decline depth. It is down -36.8% from its rolling 252-day high of $219.69, set on 2025-07-31 — 301d ago.
Is PTC a falling knife?
Not by the strict technical definition. PTC is down -36.8% from its 52-week high, but that high was set 301d ago — more than 120 days. A falling knife is usually a recent breakdown from a fresh high, not an established multi-quarter downtrend. PTC is still on the Amber List for decline depth, but the freshness component of a falling knife is missing.
Is PTC 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 PTC trading inside its 52-week range?
At $138.79, PTC sits 8.9% of the way from its 52-week low ($130.89) to its 52-week high ($219.69). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has PTC been declining?
The current 36.8% decline accrued over 301d, which annualizes to roughly -44.6% 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 PTC compare to its sector?
There are 179 other Technology tickers on Broken Stocks: 114 Red, 44 Amber, 21 Watch, with 115 showing recovering structural signals. Median sector decline is -42.2% — PTC's decline is shallower than the sector median.
Does PTC'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.
