Saudi Arabia's stock market rose on Monday, extending gains from the previous session helped by banking shares, while most other major Gulf markets were also up.

Saudi's benchmark index gained 0.6%, with Al Rajhi Bank 1120.SE gaining 1% and Saudi Aramco up 1.1% on its fourth day of trading.

Saudi state oil company Aramco is due to join the Tadawul index and global benchmarks such as MSCI and FTSE this week, which according to analysts should fuel further demand, particularly from "passive" investors who track such indexes.

Aramco raised $25.6 billion on Dec. 5 through its IPO and plans to exercise a 15% greenshoe option in whole or part during the first 30 days of trading. If the option is exercised in full, the total raised from the IPO would amount to $29.4 billion.

In Dubai, the index added 0.6%, extending gains for a fifth consecutive session. Dubai's largest lender, Emirates NBD Bank, increased 2% and Dubai Islamic Bank was up 0.4%.

Amlak Finance soared 11.7% after the Sharia-compliant lender announced on Sunday its action plan to handle accumulated losses.

The Qatari index opened up 0.2%, driven by a 1% gain in the Gulf's largest lender, Qatar National Bank, and a 1.1% rise in Industries Qatar.

The Abu Dhabi index traded flat, with telecoms firm Etisalat easing 0.7%, while First Abu Dhabi Bank rose 0.3%.
