Why does this matter? Significant stock moves – up or down – deserve your attention. Sharp declines in fundamentally strong names can offer smart buying opportunities. And when momentum aligns with solid fundamentals, riding the trend can be highly rewarding. Among these stocks, we find First Solar (FSLR) and Amgen (AMGN) attractive.

No matter where SPX stock goes, your portfolio should stay on track. See how the Trefis High Quality Portfolio can help you do that.

Picking winners on a consistent basis is not an easy task – especially given the volatility associated with a single stock. Instead, the Trefis High Quality (HQ) Portfolio, with a collection of 30 stocks, has a track record of comfortably outperforming its benchmark that includes all 3 — the S&P 500, S&P mid-cap, and Russell 2000 indices. 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.
