Multiple Tops
See: Triple Bottom. See: Triple Top. See: Charts. See: Technical Analysis.
A given stock keeps trading between $15 and $20 a share. Each time it looks like it's gonna break out from that $20 and make a new high at $25, it...doesn't. It sags. Like an old man's breasts, which just won't firm up in the weight room.
The stock is making multiple tops at $20 and it just won't break out. Maybe next time cut down on the sugar.
