The third quarter’s regional flow data, published this week by Kuwait’s Kamco Invest, records the largest foreign sell-off in Gulf equities since the series began in 2019: a net $2.3 billion across the six markets, of which about $1.5 billion came out of Saudi stocks. What the headline number does not record is who stood on the other side of the trade. Saudi investors bought a net SR5.6 billion ($1.49 billion) of their own market in the quarter, reversing net sales of SR5.8 billion in the second, and institutions did nearly all of it, with SR5.9 billion in net purchases.
The year-to-date arithmetic reads differently from the quarter’s. Foreign investors remain net buyers of SR6.7 billion in Saudi stocks for 2026 even after the third-quarter sales. Across the wider Gulf they have sold a net $1.1 billion this year, against net buying of $11.7 billion over the same nine months of 2025. Riyadh is the market where the foreign position has held, and the only one that also drew meaningful money from inside the region: GCC investors from outside the Kingdom added a net $323.3 million of Saudi stocks in the quarter, the most of any market in the bloc.
The outflows elsewhere were smaller but broader. Foreign investors sold a net $414.3 million in Dubai, $284.1 million in Kuwait, $36.1 million in Abu Dhabi, $26.5 million in Oman and $21.8 million in Bahrain, while Qatar drew a modest $10.9 million of net buying. Regional trading value fell 14.4 percent to $135 billion in the quarter, and thinner trade makes any given flow move prices further than it would in a crowded market. Kamco attributed the quarter’s divergent flows to geopolitical developments. Vijay Valecha of Century Financial argued that reforms such as the removal of the qualified foreign investor requirement keep the structural case in place for long-horizon money, and expects regional momentum to return in the fourth quarter.
The useful way to read the quarter is as a transfer of inventory. Faster foreign money that bought the second quarter’s Saudi rally, when the Kingdom was the only Gulf market with net foreign buying, sold into the third; the domestic institutional layer, pension and fund capital that earns in riyals and reports in years, took the inventory in. February’s decision to open the main market to all foreign investors widened the doorway in both directions, and a doorway that swings both ways is what a mature market looks like from the flow desk. The same two-way logic ran through this week’s investment bulletin, where a one-third rise in inward investment arrived alongside a near-doubling of Saudi capital deployed abroad.
The quarter also confirmed where the region’s trading actually happens. Five of the Gulf’s ten most-traded stocks were Saudi, with Al Rajhi Bank’s $6.6 billion of turnover leading the regional table and Saudi Aramco’s $3.7 billion behind it. Whichever direction net flows run, they run through Riyadh, and that concentration of liquidity, not any single quarter’s net line, is the asset the exchange’s reform program has been built to protect.
The fourth-quarter report will show whether the domestic bid held and whether the foreign line turned with it. The series’ own short history argues for patience with single quarters: the second quarter’s story was foreign buying concentrated in Riyadh, and the third’s was domestic buying in the same place. The buyers rotate. The destination has not.
