U.S. Treasury note investors were more optimistic this week, according to a JPMorgan weekly poll of clients.

The net percentage of investors holding Treasury notes increased to 13 percent this week from 2 percent the previous week. The net figure is the difference between the percentage of investors long on Treasury notes (expecting prices to increase), and the percentage short Treasury notes (expecting prices to decrease.)
