Diversification is a risk management technique that involves allocating investments among various financial instruments, industries, and other categories. The goal is to minimize the impact of a single asset's poor performance on the overall portfolio. By diversifying, an investor can reduce the volatility of their portfolio because different assets often react differently to the same economic event.
For example, if a trader invests solely in tech stocks, they may face significant losses if the market for tech declines. However, if they also invest in commodities and bonds, the poor performance in one sector may be offset by stable or rising performance in another. Related concepts include asset allocation and correlation, which further help inform diversification strategies. While diversification does not eliminate risk entirely, it is a fundamental principle that can lead to more stable returns over time.
