# Ticker Company Name 1-D

Returns
1 APP AppLovin -5.8% -21.0%
2 KHC Kraft Heinz -5.7% -7.6%
3 ORCL Oracle -3.4% -10.6%
4 TGT Target -3.0% 8.5%

8 MSFT Microsoft -2.3% -8.2%
9 DGX Quest Diagnostics -2.3% 6.9%
10 NFLX Netflix -2.2% -9.0%

 
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 them, we find Quest Diagnostics (DGX) attractive while AppLovin (APP) looks attractive but volatile.

Individual stocks swing, but a balanced asset allocation doesn’t. Trefis’ Boston-based wealth management partner blends strategy and discipline to smooth out market noise.

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.
