Diversification in a portfolio is an important strategy for long-term success. A well-built portfolio should not be concentrated heavily on a single stock or asset class or sector. Rather a portfolio should hold various assets such as growth stocks, dividend stocks, domestic stocks, foreign stocks, commodities, ETFs, closed-end funds, bonds, etc.
Holding a diversified group of assets cushions a portfolio during rough market conditions and also provides stable and consistent returns when markets overshoot.
