Glide Paths

Interactive visualization tool for comparing investment risk glide path strategies — commonly used in retirement planning and target-date funds.

Features

Compare 5 different mathematical models for managing risk over time:

Model	Description
Linear	Constant, steady risk reduction
Convex	Aggressive early reduction, slower later
Concave	Slower early, aggressive near the end
S-Shape	Sigmoid curve with gradual acceleration
Parabolic	Quadratic curve centered on a peak time

Adjust parameters in real-time:

• Total time period
• Steepness for convex/concave paths
• Peak timing for parabolic curves
• S-shape steepness

Installation

git clone https://github.com/tomlupo/glide_paths.git
cd glide_paths
uv sync

Usage
