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.
