What it is
A stock within a few percent of its 52-week high has almost no overhead supply. That means nobody who bought in the last year is sitting on a loss and waiting to sell at break-even. That is why new highs tend to lead to more new highs.
The idea has a well-known study behind it. In 2004 the Journal of Finance published "The 52-Week High and Momentum Investing" by Thomas George and Chuan-Yang Hwang. It found that how close a stock traded to its 52-week high said more about its returns over the following months than its past returns did.
How it is measured
Take the highest price of the last 252 trading days, about one calendar year. The distance from the high is the latest price divided by that high, minus one. A stock at $95 with a 52-week high of $100 is 5 percent under its high. A stock at its high reads 0.
52-week high vs all-time high
A 52-week high looks back one year. An all-time high looks back over the whole time a stock has traded. A stock that fell hard two years ago can make a new 52-week high while it still trades far under its all-time high, and it still has holders from before the fall who bought higher. Breakaway counts both: near the 52-week high in the check, and a further point in the Quality Score for a stock near its highest close on record.
How Breakaway uses it
The 52W HI check fires when the close is within 5 percent of the highest price of the last 252 trading days. Once lit, it stays lit until the close is more than 8 percent under that high. Being near the high also earns points in the trend part of the Quality Score. A stock within 5 percent of its highest close on record gets a further point for being at a multi-year high. The New highs list in the scanner shows every stock within 2 percent.
How to read it
The check means the most when it fires for the first time in a while, and the Fresh list shows those. A stock that has been lit for weeks is in a strong trend and may have run far already. Check the distance from the 21-day EMA before you chase it. One that just lit it after a long quiet stretch is the classic breakout.
