The shares of Saudi Aramco opened at a decrease of about 0.6% in the beginning of trading today, Wednesday, to fall to about 37.5 riyals (ten dollars), in the first days of the company's shares joining the MSCI Emerging Markets Index.

The stock continued its losses during today's trading, falling to less than 37 riyals, down by more than 2%.

The company's entry into the index was based on yesterday's closing price. Also, the shares of the giant oil company were listed today on the Saudi Stock Exchange index, "Tadawul", which fell 0.25% in early trading, before rising later.

The weight of Aramco on the index is 12%, to come after Al-Rajhi Bank, which has the largest weight by about 14%.

Two market sources told Reuters that Aramco's losses are likely from profit-taking sales.

Arqaam Capital estimates that joining the MSCI Index will result in inactive flows of approximately $ 710 million.

On Thursday, the stock will join the world record FTSE, and Capital Figures expects flows in this case of about $ 400 million.

State-owned Aramco listed its shares on the Saudi Stock Exchange last week after raising $ 25.6 billion in the world's largest IPO.

Aramco shares were priced at 32 riyals, and they rose by the maximum at 10% in the first trading days, and rose about 1.6% from the closing price on December 11th since then, but lost momentum yesterday for the first time since the listing.

The current price at the company’s market value exceeds two trillion dollars, which was the value sought by Saudi Crown Prince Mohammed bin Salman.

But analysts said that the size of the company is not everything, and pointed to the risks of slowing net income growth in the event of stable oil prices.
