* Saudi's Bahri falls on lower Q4 profit * Dubai's Deyaar gains on FY results * Abu Dhabi's ADCB climbs after three-way banking merger * Egypt's Ezz steel continues to rise on rating hike By Shakeel Ahmad and Abinaya Vijayaraghavan Jan 31 (Reuters) - Saudi Arabia's stock market, which introduced the MSCI Tadawul 30 index, fell on Thursday as its bank stocks slid, while Dubai gained sharply lifted by corporate earnings results.
Saudi Arabia's main index fell 0.3 percent. National Shipping Company of Saudi Arabia dropped 2.5 percent after its fourth-quarter net profit more than halved.
But Riyad Bank rose 2.1 percent after posting a 39 percent gain in its fourth-quarter net profit, according to Reuters calculations.
The MSCI Tadawul 30 Index (MT30) was down 0.2 percent. The index of the 30 largest securities listed on the Saudi Arabian Equity Market went live on Wednesday.
The index's top two heavyweights Al Rajhi Bank and Saudi Basic Industries fell 1.2 percent and 0.5 percent respectively.
Separately, Saudi Arabia is set to join the emerging-market indexes of MSCI and FTSE Russell later this year. That is expected to attract $15 billion of "passive" benchmark-linked funds and billions more in active funds, regardless of low oil prices or geopolitical tensions.
Saudi's economy grew at a pace of 2.21 percent in 2018, buoyed by strong oil sector growth. The government did not break down the fourth-quarter data, but full-year growth figures suggested economic growth accelerated in the last quarter.
In Dubai, the index rose 1.1 percent, boosted by a 1.5 percent increase in the emirate's biggest lender Emirates NBD, and a 1.4 percent gain in Dubai Islamic Bank (DISB).
DISB, which fell in the last session after declaring a lower dividend, was upgraded by Arqaam Capital, with a target price of 7.6 dirhams, up from 7.2 dirhams.
The brokerage said it welcomed the improved allocation of capital, retaining about 60 percent of its earnings rather than paying out 60 percent as it had in the past.
