Signal guide
Price crossing its moving average,
explained with real charts
The second family of signals: the price itself crossing one of its SMAs. Every chart below shows real daily prices; the marked dot is an actual cross event, not an illustration.
How to read them
The shorter the average, the earlier — and noisier — the signal
Unlike the golden cross and death cross, which compare two moving averages to each other, these signals compare the price itself to a single moving average. Above the line is read as bullish, below as bearish — and the choice of line sets the trade-off: short averages fire early but often; long averages fire rarely but mean more.
Price × SMA50 — the momentum line
Crossing above the 50-day says the stock has recovered its recent range — an early trend-change signal. Fast, frequent, best used as a heads-up rather than a verdict.
Price × SMA100 — the intermediate check
The 100-day sits between momentum and regime. Reclaiming it after a correction is often the first sign the correction is over.
Price × SMA150 — trend confirmation
Slow enough to ignore most noise. Institutions use the 150-day (30-week) line in stage analysis: above a rising SMA150 is the classic definition of a stock in an uptrend "stage 2".
Price × SMA200 — the regime line
The most-watched line in technical analysis. Above the 200-day is broadly "healthy"; below it is where bear markets live. Crosses are rare — when price reclaims or loses the 200-day, it makes financial headlines.
Limits
What price × SMA crosses don't promise
All of these are lagging signals built from past prices. The shorter lines whipsaw often — price can cross the 50-day several times in a single month of sideways trading — and even the 200-day produces false starts near market turning points. Traders pick the line that matches their horizon (fast heads-up vs. slow regime check) and weigh crosses with volume, fundamentals and market conditions. Everything here is for education, not financial advice.
FAQ
Price × moving average questions
- Which moving average should I watch?
- It depends on your horizon: SMA50 for early momentum shifts (noisy), SMA100/SMA150 for intermediate trend changes, SMA200 for rare regime-grade signals. Many traders watch a short and a long line together.
- What does it mean when a stock crosses its 200-day moving average?
- It's read as a regime change: reclaiming the 200-day suggests the long-term trend is turning healthy; losing it is where bear markets tend to live. It's rare enough to make financial headlines.
- How is this different from a golden or death cross?
- Golden/death crosses compare two moving averages (SMA50 vs SMA200). These signals compare the price itself to one moving average — they fire earlier and more often.
- Can I get alerted when my stock crosses a moving average?
- Yes — Korpious Stock Alerts watches price crosses of SMA50, SMA100, SMA150 and SMA200 (your choice) and sends one email or Telegram alert the moment one fires. 50 alerts free, then 1¢ each; no subscription.
