Single stock can be risky, but there is a huge value to a broader diversified approach. If you seek an upside with less volatility than holding an individual stock, consider the High Quality Portfolio (HQ) – HQ has outperformed its benchmark – a combination of S&P 500, Russell, and S&P midcap index, and achieved returns exceeding 91% since its inception. Risk management is key – consider, what could long-term portfolio performance be if you blended 10% commodities, 10% gold, and 2% crypto with HQ’s performance metrics.
