The highest price a stock has traded in the past year.
Treated as a ceiling and behaves like the opposite — at a genuine high, nobody from the past year is underwater to sell into you.
A breadth measure counting stocks making fresh 52-week highs against those making fresh 52-week lows.
In a healthy advance new highs vastly outnumber new lows. Expanding new lows while the index still rises means damage is spreading beneath the surface.
