Samsung Group’s market capitalization has topped 900 trillion won, or approximately 628-point-four billion U.S. dollars, for the first time following a surge in Samsung Electronics’ stock price.

According to the Korea Exchange on Wednesday, the combined market cap of Samsung Group’s affiliate companies stood at nearly 908 trillion won, or around 634 billion dollars, as of Tuesday, up more than 365-point-five trillion won, or nearly 255 billion dollars, from the end of last year.

Samsung Electronics, which accounts for the largest share of the group's value, jumped on the back of a tech rally on Wall Street and expectations of recovery in the chip sector.

Samsung Electronics shares closed at 98-thousand-600 won, or roughly 69 dollars, on Wednesday, up more than 85 percent from the end of last year.
