Briefly explain diversification and portfolio risk and one common misconception about it.

# Diversification and Portfolio Risk **Diversification** is the practice of spreading investments across different assets, sectors, or geographic regions to reduce risk. The core principle is that different investments don't all move in the same direction at the same time—when some decline, others may hold steady or increase. **How it reduces portfolio risk:** By holding multiple uncorrelated or negatively correlated assets, you reduce *unsystematic risk* (company or sector-specific risk). While individual holdings may be volatile, the overall portfolio becomes more stable because losses in some positions are offset by gains or stability in others. ## Common Misconception **"Diversification eliminates all risk"** Many investors believe that spreading money across enough investments makes their portfolio "safe." In reality: - Diversification only reduces **unsystematic risk** (specific to individual companies/sectors) - It cannot eliminate **systematic risk** (market-wide risk affecting all investments) - During major market downturns, even well-diversified portfolios typically decline because correlations between assets often increase during crises For example, in 2008, nearly all asset classes fell together. Diversification helped reduce losses compared to concentrated positions, but it didn't prevent them entirely. True risk reduction requires understanding *what* you're diversified across and recognizing that some market forces affect everything simultaneously.
