If you hold index options or shares over a weekend, the account does not change from Friday afternoon to the next session. That does not mean nothing happened. Perpetual contracts on the indexes and on the largest stocks trade around the clock, weekends included. A Sunday check takes five minutes and tells you whether Monday starts where Friday ended.
First: the index perps
Open Trader. While the cash market is shut it shows the implied open, and the Perps & Futures tab carries the index perps themselves. That figure is each index perp’s price now, measured against the same perp’s price at Friday’s cash close. Both prices come from one market, so the comparison is clean.
Read it as a market price on another venue. On 4 October 2026, a Sunday, the S&P 500 perp held about $349 million of open interest. That is a real market with real money in it. It is also far smaller than the cash index, and it can move on thin weekend trading. The implied open sets out what the figure is and what it is not.
Second: which names moved
Below the index figures are the seven largest index names, shown unweighted with the largest move first. If you hold one of them, find it. If you hold the index, look at whether the names agree. Seven names moving together is a different weekend from one name moving alone.
Third: funding
Each perp carries a funding rate, charged hourly. Positive funding means longs pay shorts. On 4 October 2026 most large markets showed the same funding of about 5.5% a year, which is the formula’s resting value. A market sitting at the resting value tells you little. A market far from it, or sharply negative, tells you one side is paying to hold. That is positioning, and it is worth a glance.
Fourth: be careful with stock token quotes
If you also hold Robinhood stock tokens, do not read their weekend quote as a price. Outside market hours the quote goes wide. On Sunday 4 October 2026 the median spread across the list was 4%. A midpoint taken from a wide quote can sit far from where the stock closed without the stock having moved at all. A wide quote is not a price has the detail.
Fifth: the written read
The Week Ahead is published on Sunday evening and quotes the perps. Dr. NoVo, a markets SI, reads the venues that stayed open and says what he read. What a markets Super Intelligence reads on a Sunday describes that pass.
What to do with it
Nothing, most weekends. A small move since the close changes no plan. A large one is a reason to have your plan ready before the session starts, so you are not making it while the screen is moving.
You do not have to remember to look. Trader sends a push the first time an index perp is half a percent from its close, and setting up the off-hours perp push covers that. NoVo shows the reading. It makes no forecast and it cannot touch the positions.
