Risk: A solid way to gauge risk is by checking how much CEG falls in major market downturns. During the Inflation Shock, it dropped about 24%. While that’s less severe than some other crises, it shows even strong stocks can take a hit when the market turns. No stock is immune to sudden shocks, no matter the fundamentals.

Why is that? As a group, HQ Portfolio stocks provided better returns with less risk versus the benchmark index; less of a roller-coaster ride, as evident in HQ Portfolio performance metrics.
