Saudi Stocks Post Their Biggest One-Day Gain Since May
The index added 2.3% and 225 of 254 stocks rose. The story is the breadth and the volume, not the headline number, and the record still has a hole in it.
Saudi stocks posted the largest one-day gain in our records on Tuesday, and they did it on the heaviest trading of any session we hold.
The Tadawul All Share Index rose 2.3% to 9,986.45, a day after adding 3.4%. Two sessions have recovered 5.8%, arithmetic on the official closes, not a forecast. What makes the move unusual is not its size but who took part. Of the 254 Main Market stocks, 225 rose, and eleven closed at the 10% limit. A market lifted by a few heavyweights looks nothing like that. This one was bought across the board, from banks and insurers down to cements and small industrials, which is the pattern that lasts.
Turnover supports the same reading. At SAR 7.16 billion, about $1.91 billion, Tuesday was the busiest session in our records, which run back to September 30, and well above Monday's SAR 5.18 billion. Higher prices on heavier volume means buyers paid up rather than drifted.
Leadership was a continuation, not a new idea. The five best performers on the Main Market all closed at or within a hair of the 10% limit, and all five had already risen on Monday, by between 1.5% and 7.4%. BinDawood Holding, the grocery chain, was the cleanest example, up 5.3% on Monday and locked at the ceiling on Tuesday. Qassim Cement and Saudi Ceramic ran alongside it, with Tourism Enterprise and Alamar Foods. The downside mirrored it. Every one of the five largest decliners had risen the previous session: Nahdi Medical after 6.2% on Monday, the National Company for Learning and Education after 4.7%, and Arabian Cement and Alujain Corp giving back part of their own gains. The data does not say why these names moved, and this brief will not pretend otherwise. What it shows is a market trading on its own momentum, with the winners of one session becoming the raw material of the next.
Two cautions. The index closed 0.75% below its intraday high of 10,061.92, so the last hour gave back part of the gain. And after two strong sessions it still sits 5.7% below its October 6 close of 10,589.95. The 20 sessions between October 7 and October 25 are missing from our record, so this site can show its endpoints but not its path. We are reconstructing them rather than estimating. A filled-in guess would be worse than a visible hole.
Set the two sessions against where the year has gone. The index is down 4.8% in 2026, and the exchange's own 52 week record puts its low at 9,367.91 on 25 October, two sessions before this rally began. A 5.8% recovery is impressive in isolation and smaller against a market that has spent the year giving ground.
What to watch on Wednesday is whether buyers return at these levels, or whether Tuesday's close marks the point where the rally was sold to them. Breadth is the first check. If advancers fall below half the market while the index still holds, the index is being carried by fewer names.

Company Of The Day
ACWA Power (2082). The company behind much of Saudi Arabia's power and water buildout is a different animal from a bank or a cement maker, which is why it is worth understanding regardless of one session's move. It develops, owns and operates generation, desalination and green hydrogen plants, sells the output to sovereign off-takers and national utilities under long-term contracts, and its project list runs from the Gulf through Africa and Central Asia, including the NEOM green hydrogen development. That contract structure gives it revenue visibility a merchant generator does not have. It also makes it a financing story: the pipeline is capital hungry, so the cost and availability of project debt determine how fast it can be built. Tuesday's session put SAR 157.00 on the shares, up 4.32%, on turnover of SAR 90.8 million, about $24.2 million. The question to hold in mind is not whether Saudi Arabia needs more power, it plainly does, but whether this company can fund the next wave at a cost that leaves something for shareholders.
