Questions about SD
What people ask.
Why is SD on Broken Stocks?
SD qualifies for the Amber List on decline depth. It is down -27.2% from its rolling 252-day high of $18.45, set on 2026-03-02 — 130d ago.
Is SD a falling knife?
No. The falling-knife label usually implies a steep, severe drop — typically 30% or more from a fresh high. SD is down -27.2% 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 SD 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 SD trading inside its 52-week range?
At $13.43, SD sits 41.3% of the way from its 52-week low ($9.89) to its 52-week high ($18.45). A reading below 25% indicates price is hugging the bottom of the range; above 75%, the top.
How fast has SD been declining?
The current 27.2% decline accrued over 130d, which annualizes to roughly -76.4% 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 SD compare to its sector?
There are 52 other Energy tickers on Broken Stocks: 13 Red, 16 Amber, 23 Watch, with 22 showing recovering structural signals. Median sector decline is -27.1% — SD's decline is deeper than the sector median.
Does SD'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.
