What is the SCOTUS Mississippi case about?

It examines whether states can require ballots to be received by Election Day, or count those postmarked by Election Day that arrive later. A ruling expected by June 2026 could set a national standard and prompt state law changes affecting close races and market expectations.

How could the Supreme Court mail-in ballots ruling affect markets?

It may compress the vote‑count timeline and shift turnout assumptions, changing sector odds on regulation and spending. Expect earlier, sharper swings around court milestones and the 2026 midterms, with moves in healthcare, energy, tech, and defense as investors reprice policy paths.

What should Swiss investors do before the ruling?

Set rebalancing bands, decide on CHF hedging, and use limit orders. Check W‑8BEN status, custody and FX fees, and expense ratios for U.S. ETFs on SIX. Write a simple risk plan so you can act consistently if volatility rises around court dates and election events.

Does this change Swiss or U.S. tax rules for investors in CH?

No. The case does not alter tax laws. Swiss investors should still expect U.S. dividend withholding, typically 15% with a valid W‑8BEN. Review your broker’s documentation, keep records for Swiss tax filings, and factor trading costs if activity increases around political headlines.
