SK Hynix (SKHY) Now Trades 24/7 on Backpack 

SK Hynix (SKHY) is now available for 24/7 trading on Backpack. The Nasdaq-listed ADR joins SPCX, MU, and SNDK as the fourth ticker tradable outside standard U.S. market hours. 

Weekend Trading Hours

The extended trading window is open during the following periods:

• Weekends: Friday 8 PM ET through Sunday 8 PM ET, continuously
• U.S. market holidays: When traditional exchanges are closed

When the Sunday overnight session begins, routing transitions back to Backpack's standard U.S. equities flow, and SKHY trades on traditional exchanges through the following Friday close.

How Weekend Trading Works

During weekend and holiday sessions, orders route to Backpack's native orderbooks, where liquidity is provided by market makers rather than traditional U.S. exchanges. The security itself does not change. Shares bought during a weekend session are the same real U.S. securities traded during weekday sessions, and a position opened on Saturday can be sold on Monday through the standard brokerage flow once U.S. markets reopen.

This is what neobrokerage means in practice: trading capabilities built around how global markets actually move, not constrained by legacy hours designed for a single time zone.

How to Trade SKHY 24/7

The trading interface appears on the same SKHY stock page across web and mobile. During weekend and holiday sessions, an expanded view surfaces Backpack's native order book, showing live bids and asks from participants trading in real time. Fractional share trading is available.

Liquidity during weekend and holiday sessions may be thinner than during regular U.S. market hours. Spreads may be wider, and prices may move differently while traditional U.S. exchanges are closed.
