In cricket, the skipper doesn’t send the biggest slog-hitter up the order when the ball is still brand-new and swinging. Nor does he leave the pace spearhead cooling his heels when the pitch is fresh, green and begging for seam movement. He watches conditions over by over and changes the bowlers so the team always plays to the pitch. Good investing demands the same agility: the economic wicket keeps changing, and sectors that thrive in one phase can falter in the next.
