The Tape Rewards Attention. It Punishes Reaction
Big daily moves pull hard at both greed and fear, and acting on either, day after day, is how most portfolios end up trailing the index they were trying to beat.
The Trefis High Quality (HQ) Portfolio is built for the opposite reflex: about 30 quality businesses screened for the fundamentals that survive volatile stretches, held with rules instead of reactions. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Read the movers daily; trade them rarely.
