Shares of Chinese property developer Sunac China Holdings Ltd. soared over 20% on Tuesday, as investors piled into the stock ahead of an upcoming government briefing focused on reviving the struggling real estate industry.

China's property sector has been grappling with a protracted slump, weighed down by a debt crisis and slowing economic growth. This has sent shockwaves through the broader economy, as the real estate market accounts for a significant portion of China's GDP.

However, hopes are rising that the Chinese government will unveil fresh measures to bolster the ailing property market. The State Council Information Office announced it will hold a press conference on Thursday to discuss policies aimed at promoting the "steady and healthy" development of the sector.

This sparked a broad-based rally in Chinese property stocks, with investors betting on potential stimulus measures to ease liquidity strains and revive demand in the housing market. As one of China's largest homebuilders, Sunac emerged as a major beneficiary, with its shares surging 23.64% on Tuesday in anticipation of supportive policies.
