It's a part of the "technical analysis" portfolio of analyzing stock charts. As I recall, it's a comparison of two different length moving averages, e.g., 18 vs 50 day or 50 vs 200 day moving averages.
"What's the stochastic indicator?"
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Used in technical analysis of stock, bond, commodities..etc. price charts.
The stochastic indicator is a fairly popular oscillator used to gauge price momentum and judge the age of a price move.....
The idea was orginally thought of by a Czechoslavakian..whose name I'm not sure of. Although most give Dr. George Lane the praise for perfecting it.
