Stock Return Map Maker - See Patterns of Gains and Losses
The Stock Return Map Maker displays a color-coded map of the percent returns for each buy and sell combination for a selected period for any stock listed on major U.S. stock exchanges and supported by Quandl.
Use the map to get a quick picture of profitable (green) and unprofitable (red) returns for different buy and sell dates. A map with lots of green indicates that many returns made money and a map that is predominantly red means many returns did not make money.
It's easy to see the pattern of returns of all sell dates for a given buy date. And you can see the pattern of returns for a given sell date across all buy dates.
See How to Read a Stock Return Map for details about the map.
