“Available business jet inventories look finally to be stabilizing,” UBS Investment Research noted in its latest business jet update, although pre-owned inventory remains at record-high levels, at 18 percent of the in-service fleet. While still 55 percent above prior-year levels, available business jet inventories were roughly unchanged sequentially in May over April, though a 1-percent decline in young (less than 10 years old) available aircraft listings was reported, UBS said. New delivery position inventories have also declined sequentially in both April and May. However, pre-owned business jet pricing is still weakening. “We estimate average asking prices for most young aircraft models have now fallen 30 to 40 percent from peak levels,” UBS investment analyst David Strauss said.
