Barclays analyst Robert Wertheimer begins coverage of the U.S. machinery sector with a negative view , seeing consensus estimates too high across the board with revenue for the current cycle already peaking for most of the sector. The analyst expects a sharper than expected downturn for North American trucks, with another peak level eight years away; the tractor supercycle is only two years in a downturn, while the prior two supercycles saw seven consecutive down years in machinery sales, Wertheimer says.
