A new high tells you what the market already believes. The harder question is which of these runs management itself is underwriting. Our Guidance Momentum screen tracks exactly that: stocks where the company raised its own forward numbers.
One more pattern worth noticing: 3 of the 7 names are Health Care stocks. When a whole group is making new highs together, a health care ETF like XLV, which holds 3 of the 3 largest of them, is one way to own part of the group's strength without betting on which single name leads it from here.
Strength Is A Clue. It Is Not A Plan
A stock at its 52-week high has momentum on its side, and momentum is a real force. It is also the most crowded signal in the market, and what separates a run that lasts from one that tops is usually the business underneath.
Checking that business, across thousands of names, is how the Trefis High Quality (HQ) Portfolio is assembled: roughly 30 companies that pass the quality screens, rebalanced on 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 highs point; let the discipline decide.
