SNDK pre-market and after-hours

What the extended-hours move is telling you

SNDK is down +3.84% outside regular hours. Extended-hours volume is a fraction of the regular session, so a move of this size is being set by comparatively few orders. It is a signal about what a small number of participants think, not a settled price.

Pre-market runs 4:00am to 9:30am ET, after-hours 4:00pm to 8:00pm ET. Spreads are wider in both, and the further from the bell you go, the thinner it gets.

Where SNDK sits in the options structure

Dealer positioning does not stop overnight. The largest positive-gamma strike sits at 1400, which tends to act as friction on the way up. The largest negative-gamma strike is 1200; below it, hedging flow amplifies moves rather than absorbing them. Max pain for the front expiry is 1350.

A pre-market gap that opens the regular session beyond one of those levels behaves differently from one that does not. See the full SNDK gamma map →

Common questions

What is SNDK trading at in the pre-market?
SNDK last traded at $1279.00. The market is closed; pre-market opens at 4:00am ET. Quoted Oct 30, 1:46 AM ET.

What time does SNDK pre-market trading start?
Pre-market trading runs from 4:00am to 9:30am ET, and after-hours from 4:00pm to 8:00pm ET. Volume is far thinner than the regular session, so spreads are wider and a single order can move the quote more than it would during the day.

Can I trade SNDK before the market opens?
Most brokers allow pre-market orders from 4:00am ET, though many restrict them to limit orders only. Because extended-hours liquidity is thin, a market order in SNDK before the open can fill materially away from the last quote.
