No clear trend: not near its 52-week low, and not in a steady uptrend.
Swung more than 82% of stocks we rank over the past year (volatility 69% a year).
How this is worked out
The Price check reads only the chart, the price side of the Momentum score in words; it is not the MoatMap Score.
- Still falling: It set a new 52-week low in the last two weeks, after a deep fall.
- Finding a floor: It fell hard, but has set no new low for more than two weeks.
- Turning up: It has climbed off its low and is back above a rising 50-day average.
- In an uptrend: It is near its 52-week high and above its 200-day average.
- No clear trend (this stock): None of the above: no recent deep fall and no steady climb.
- No read yet: Not enough price history yet: it needs a year of trading.
In past US falls, waiting for Turning up cut the chance of another 20% drop from 42% to 33%. Returns were no better, and 33% of turns failed.
The exact rules
Still falling is a new 52-week low in the last two weeks, at least 25% below the high, with the low set after the high. Finding a floor is the same fall with no new low in the last two weeks. Turning up is 20 or more trading days without a new low, at least 10% off it, and back above a rising 50-day average. In an uptrend is above the 200-day average, with the 50-day average above the 200-day, and within 15% of the high. No clear trend is everything else. No read yet is under 252 trading days of history, or missing data. A new state shows once it has held for three trading days.
In 2,112 US drawdowns since 2001, buying while the price was still falling was followed by a further 20% drop 42% of the time. Waiting for a turn (the Turning up rule above) cut that to 33%, at about 7% higher prices and with no better returns. Part of that cut is simply not buying: 13% of falls never turned, and waiting kept those out. Among turns that were bought, 38% still fell another 20%, and 33% of turns were followed by a new low within six months. The benefit was largest in crashes such as 2008 and 2020.
What it measures: how much the price moved day to day over the past year, scaled to a yearly figure (annualised volatility) and ranked against every stock we cover. Very calm under 20% a year, Calm 20 to 30%, Average 30 to 40%, Bumpy 40 to 55%, Very bumpy above that.
What we found: across about 13,500 stocks in 34 markets (2002 to 2025), past swings were a good guide to the next year's, and bumpier stocks fell further. How much further changed too much between eras to put a number on it.
Calm is not safe: a calm stock can still slide steadily.
