There are numerous companies to choose from in the stock market, but the most effective way to build a high-growth portfolio is through diversification. Investors should select top-performing companies from different sectors to spread their investments across industries. Additionally, including gold in the portfolio can act as a hedge—as it helps protect against potential losses during times of global uncertainty, crises, or war. Historically, while stock prices tend to fall during such periods, gold often gains in value, providing a stabilizing effect on the overall portfolio.
