Volatility Is The Cost Of Owning Stocks. Concentration Makes It A Bill
Every name on these lists made a move big enough to notice. A diversified holder reads that as noise; a concentrated holder feels it as real money. The difference is not the stock, it is the portfolio around it.
Building that portfolio is what the Trefis High Quality (HQ) Portfolio does: roughly 30 businesses with the cash generation and balance-sheet strength to absorb bad days, selected and rebalanced by rules. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Let the movers list remind you why diversification exists.
