Market Analysis

How the tape may move from the last update’s mark — not from the open, and not the session % already printed.

The 8-Week Bill auction acts as a liquidity stress test. Weak demand (higher rate) forces yields up across the curve, hurting $TLT. Strong demand (lower rate) supports $TLT by anchoring the short end.

Expected Move From Here -0.8% to +0.8% From last update, not from the open

Certainty 65%

Why

Historical correlation between bill auction weakness and $TLT declines is high. The range reflects typical volatility around auction prints. Certainty is moderate due to potential offsetting macro news.
