In an example of how markets go up like an escalator and down like an elevator, auto parts producer Linamar Corp. (LNR.TO) has completed a round trip within the SIA S&P/TSX Composite Index Report. Linamar left the Red Zone back in June and steadily climbed up the rankings over the summer, briefly returning to the green zone last week before plunging back down the rankings and returning to the Red Unfavored Zone on Friday. Linamar is currently in 120th place, down 42 positions in the last month.
