Absolute Breadth Index - ABI

There is an absolute breath index, but usually Life Savers mints take care of that pretty quickly. This is the Absolute Breadth Index, or ABI, which is something completely different. The "breadth" here refers to how broadly a given market move is running. Doesn't matter whether the prices are going up or down, the notion simply refers to whether its only one stock that is a large element of a given index (like Apple in a tech index) which has declined...or whether more or less all of the stocks on a given day have declined because China just entered the market with a better phone stolen from American ideas at half the price. The calculation? Easy. It's just the absolute value of the difference between the number of advancing issues and declining issues.
