# 52-Week High/Low Stock Alerts: What to Measure Against

## Why “alert me at the 52-week high” doesn’t work

A 52-week high or low isn’t a fixed number — it updates every time the stock prints a new one. Set a fixed-price alert at today’s 52-week high and it’s already wrong the next time the stock makes a new high; you’d have to look it up and reset the alert every time. That defeats the point of tracking “distance from the extreme” in the first place.

## What actually matters: percentage distance from the extreme

The useful question is usually one of two things:

*   **How close is this stock to breaking out?** — percentage below the current 52-week high, e.g. “within 3% of its 52-week high.”
*   **Is this a real bounce, or still near the bottom?** — percentage above the current 52-week low, e.g. “up 5% off its 52-week low.”

Both only make sense as a live percentage against a moving extreme, not a number you looked up once. A watcher that recalculates the 52-week high/low continuously stays accurate without any manual upkeep — the baseline moves as new highs or lows print, and the percentage threshold stays meaningful.

## Setting it up

1.  Pick the ticker (stock or ETF).
2.  Pick the baseline: **52-week high** (breakout watching) or **52-week low** (bounce watching).
3.  Set the threshold — e.g. within 3% of the high, or up 5% off the low.
4.  Optionally stack a second condition — e.g. “within 3% of the 52-week high **and** above the monthly average” — so a breakout alert only fires when the broader trend agrees too.
5.  Save it. Because it re-arms automatically, you’ll hear about it every time the condition is true again, not just the first time.
