RLX Technology, a Chinese ADR, saw its stock price soar 5.52% in pre-market trading on Tuesday. This significant uptick comes in the wake of positive news from China's financial sector, which has bolstered investor confidence in Chinese stocks listed on U.S. exchanges.

The rally can be attributed to an announcement from the People's Bank of China (PBOC), stating its commitment to provide support to Central Huijin Investment Ltd., a sovereign fund, when necessary. This move is part of a broader effort to stabilize China's capital markets, which have been under pressure recently. The central bank's pledge to step up funding aid through a re-lending program has been warmly received by investors, triggering a surge in Chinese ADRs and ETFs.

While RLX Technology was not specifically mentioned in the news, the overall positive sentiment towards Chinese stocks listed in the U.S. appears to have benefited the company. This development comes as China's state-backed funds, including Central Huijin, have announced plans to purchase local stocks to support the market. The ripple effect of these measures seems to have extended to U.S.-listed Chinese companies, with RLX Technology emerging as one of the beneficiaries of this renewed investor optimism.
