The Muscat Stock Exchange’s official September 2026 monthly statistics show that the MSX 30 closed at 7,566.82 points, down 37.19 points, or 0.49 percent, from August. The exchange’s September statistical PDF, posted on 30 September, records total turnover of OMR 914,016,260, a 6.40 percent month-on-month decline from OMR 976,494,054. Executed trades moved in the other direction: 199,083 in September compared with 178,335 in August, an increase of 11.63 percent. Qatar News Agency reported the main figures on 3 October, rounding the index to 7,566 and turnover to OMR 914 million. The precise values in this article follow the primary exchange table where it supplies them; reported rounded market-cap values and QNA’s security breadth counts retain their stated precision.

Market capitalization at the end of September was reported at about OMR 39.23 billion, against about OMR 38.64 billion at the end of August. The exchange described the increase as 1.53 percent. QNA characterized the gain as about OMR 590 million and attributed it to higher capitalization among closed companies and publicly traded joint-stock companies listed on the parallel market. Because both capitalization figures are rounded and market capitalization is a stock measured at a point in time, this comparison should not be confused with cash entering the exchange during September or with turnover. Turnover measures the value of securities traded over the month; the end-period capitalization estimates the market value of listed instruments at the close. The two indicators answer different questions and can move in different directions, as the closing index and monthly traded value did in this reporting period.

The official monthly table also records 3,376,297,236 shares traded in September, versus 3,472,012,594 in August, a decline of 2.76 percent. Total turnover fell more sharply, by 6.40 percent, to OMR 914.016 million from OMR 976.494 million. At the same time, the number of transactions rose by 11.63 percent. These measures are not interchangeable: share volume counts shares, turnover sums the reported value of transactions, and trade count records executed transactions. A higher number of trades alongside lower share volume and lower turnover does not, on its own, reveal why participants traded or whether the market became more liquid. The statistics do not report average transaction size, bid-ask spreads, investor-level flows or the distribution of trades across securities. Those additional measures would be needed to assess market depth or trading conditions beyond the headline totals.

The wider market picture was mixed. QNA reported that 54 securities rose in price during September, 41 declined and 13 were unchanged. It also said the Financial Sector Index gained 220 points to finish above 13,600, while the Industrial Sector Index added about 200 points to close at 9,812. These selected sector movements did not prevent the MSX 30 from ending lower for the month. The counts describe how many securities moved in each direction, not how much their market values changed; a small number of larger constituents can influence a capitalization-weighted index differently from a simple count of gainers and decliners. The exchange’s monthly statistics provide index and trading aggregates, while QNA supplies the breadth summary. Neither source establishes that a particular sector caused the overall index movement or explains investor decisions.

This is a descriptive account of one monthly market report, not investment advice and not a forecast. The exchange’s official bulletin provides comparison figures for August and September, but two adjacent months do not establish a durable trend. Market capitalization can change with prices, listings and other structural factors; turnover and trade counts describe activity, not future returns. The sources do not provide a causal decomposition of the index decline, a complete record of investor holdings or a model for predicting October. To compare future months responsibly, the same instrument coverage, period definitions and calculation conventions should be used, and reported rounded figures should remain clearly marked as approximate. The attached dataset keeps the exact turnover, share and trade statistics from the official table separate from rounded capitalization data and QNA’s security counts. Nulls are not used to imply missing values where an observed figure is available, and no prediction is created from this single report.
