glide path
n.— «The stock portions you see on the chart show you what you’d get if you bought now, and they also give you a good idea how the lineup will change in the years ahead.…The managers reserve the right to tinker with that schedule, known in fund argot as the “glide path,” in response to the economy and the market.» —“Age-Centric Investing” by Michael Maiello Forbes Nov. 14, 2005.
