Goldilocks market
attrib.— «The bears scornfully call it the “Goldilocks market,” their way of sneering at the conventional wisdom that the economy will grow just right—not too fast, setting off inflation, and not too slow, damaging corporate profits.» —“Goldilocks Settles In, but Will Bears Be Back?” by Floyd Norris New York Times Apr. 2, 1995.
