The Implied Move Is a Price, Not a Prediction
"Priced for a 7% move" isn't the market's forecast — it's a quote for transferring risk. What the implied move is actually made of, and how to read it.

Pre-Market Brief — Thursday, May 14, 2026
Bias: Modestly higher into the open as traders lean into the Trump–Xi summit kicking off this morning. Equities are bid across the board with the S&P, Dow, and Nasdaq all firm in early trade — but the tape is leaning on geopolitics rather than data. Crude is steady above $101/bbl with the Strait of Hormuz still effectively closed, and a slightly hot jobless-claims print at 8:30 ET took some heat off the soft-landing narrative without derailing it.

Pre-Market Brief — Thursday, May 7, 2026
Bias: Modestly higher into the open. Risk-on sentiment from yesterday's record close is carrying overnight, with Dow futures up ~80 points and Nasdaq futures holding gains. The big macro driver remains Iran peace-deal speculation, which crushed crude yesterday and lifted broad equities to fresh highs. Overnight Futures Snapshot YM (Dow): ~49,990 — opened 49,507, overnight range 49,465–50,063 (up ~80 pts vs. cash close at 49,910.59) NQ (Nasdaq-100): ~28,720 — opened 28,704, ho
