| Title |
Visual exploration and discovery of atypical behavior in financial time series data using two-dimensional colormaps |
| Abstract |
This work describes two pixel-based paradigms for visual financial time series
data analysis that allow analyzing assets in overview and in detail, and offer improved
insights into the characteristics of assets compared to traditional visualization methods.
We contribute a two-dimen- sional color coding scheme for inter-/intra-asset analysis
that extends the two paradigms and supports the discovery of significant characteristics
of assets, such as atypical "against-the-market"-behavior in form of exceptional stability in case of whole market losses, or the discovery of assets in a portfolio that - while still being profitable - notably underperform the market median. We apply our techniques on real world data sets, and focus on assets of the banks of Switzerland. |
