# Time Horizon Shapes Your Investment Strategy
Your timeline to retirement or any financial goal determines which investments belong in your portfolio. This principle, called asset allocation, remains the bedrock of sound investing.
Short-term money needs different treatment than long-term wealth building. If you need cash within three years, stocks are the wrong choice.

Retirees and those within five years of retirement need stability. High-yield bonds, dividend
