· Sent · By Reveille Brief Team

A fresh spike in government bond yields around the world rattled markets on October 1, driven by Middle East tensions, UK fiscal worries, and heavy debt issuance from AI companies. U.S. stocks managed a comeback as domestic Treasury yields eased and chip stocks rallied, but European markets took a much harder hit.

TSP 101

L Funds are built from a target mix of the G, F, C, S, and I Funds that shifts over time toward more conservative investments as the target date approaches. To keep that mix on track day to day, the L Funds use automatic daily rebalancing, which adjusts the proportions regardless of how markets move.
