Samsung Electronics, Korea's leading tech firm, was the world's 22nd-largest company in terms of market capitalization, down seven notches from a year earlier, data showed Sunday.

According to the list of the global top 100 companies released by London-based accounting company PwC, the tech giant was the only Korean company on the list with the market value of $342 billion as of March.

This year's figure marked a 21 percent decrease from $431 billion a year ago that put the firm in 15th place.

The share price of the chip giant has fallen amid global uncertainties, including monetary belt-tightening to curb inflation, the war in Ukraine, the prolonged COVID-19 pandemic and a strengthening dollar.

Samsung's share price stood at 69,600 won ($54.83), March 31, compared with 81,400 won a year earlier. It has fallen further in recent weeks to a fresh yearly low of 63,800 won, Friday.

Apple topped the list with $2.85 trillion, followed by Microsoft, Saudi Aramco, Alphabet and Amazon.com, according to the data.

Taiwan Semiconductor Manufacturing came in 10th, with its market cap reaching $541 billion, up by one notch from a year earlier. (Yonhap)
