Balancing risk and reward with growth-oriented stocks

Investing in smaller growth companies comes with higher risks but also offers the potential for bigger rewards. As such, it's wise to approach these stocks cautiously. Instead of going all-in, consider adding a few of these companies to your portfolio in small doses -- perhaps 1% to 2% each. This strategy can boost your growth potential without putting too much at stake.

Another option is to create a separate, speculative growth portfolio. This approach lets you explore exciting growth opportunities while keeping your main investment portfolio safe. You'll still have a chance to benefit from some of the world's fastest-growing industries but with less risk to your overall financial picture.
