Shares of Chinese bubble tea chain Chabaidao, officially listed as Sichuan Baicha Baidao Industrial, opened 10% lower in early trade on its trading debut in Hong Kong, before plunging more than 30%.

The IPO is Hong Kong's largest listing so far this year. The company announced it had garnered net proceeds of 2.59 billion Hong Kong dollars ($330.5 million) from its IPO, before listing expenses.

Chabaidao offered 90% of its 147.7 million shares in a global offering, while the remainder 10% were offered in a public offer in Hong Kong.

Ned Davis Research says investors should reduce exposure to U.S. bonds

Investors should dial back their exposure to U.S. bonds as Fed rate cuts increasingly appear to be pushed into the future, according to Ned Davis Research.

Joseph Kalish, the fund's chief global macro strategist, said in a note to clients that NDR was reducing its exposure to U.S. bonds in its global fixed income allocation model to a market weight position from an overweight position.

"A flight to safety trade last week temporarily helped U.S. bonds outperform. But fundamentals and technicals continue to work against U.S. debt relative to other economies. The U.S. economy remains firm, inflation is sticky, and the Fed keeps pushing back when it will cut rates," the note said.

Investors should replace that exposure with incremental additions to European and Japanese bonds, according to Ned Davis Research.
