Rally leadership in two buckets: 1) Cyclical strength (energy, materials, industrials) fits hints of US economic cyclical upturn, bolstered by jobs. 2) Defensive moves like staples are a catch-up trade, not an economic signal. Market breadth profile has been strong/improving over past months, a positive story, even though cap-weighted S&P has struggled. Gains won't be as strong without tech leading, but cyclical upswing benefits non-US markets like Europe.
