Price checkNo read yetExperimental

Not enough steady price history for a read yet.

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: None of the above: no recent deep fall and no steady climb.
  • No read yet (this stock): 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.

Rules fixed before any data was fetched. Describes the chart, not a recommendation.
