Shenzhen-listed EAST Group jumped to its daily limit while Hong Kong-listed Innoscience briefly rose 10% then turned lower after Serenity said the 800V direct current stock list was only a brainstorming exercise.
EAST Group (300376.SZ) rose more than 20% and was locked at its daily limit at CNY 5.94 after Serenity, described as a "new stock god," included it in an X watchlist of 800V direct current industry-chain stocks. Hong Kong-listed Innoscience (2577.HK), another name on the list, at one point rose about 10% on June 8 but later reversed to an intraday loss of 4.40%. Serenity later said the "800V direct current" concept stock list was only a brainstorming compilation and did not represent personal optimism or endorsement of the companies mentioned. The differing reactions may reflect China’s A-share T+1 trading rule, which generally prevents same-day resale and can reinforce one-way momentum, unlike Hong Kong’s market structure.
