Mystery $50 billion Chinese medical fortune collapses in days
When Yat-Gai Au was worth $US33 billion ($50 billion) on paper, he wasn't in his Hong Kong office.
One week later, when his net worth plunged to $US10.1 billion, he wasn't around either.
Officers at the headquarters of Regencell Bioscience Holdings said both times that Au made only short visits there, before turning away reporters. The firm, a NASDAQ-listed, Cayman Islands-incorporated traditional Chinese medicine company, occupies the whole ninth floor of a tower in Hong Kong's bustling Causeway Bay, including a reception area with a large table tennis table.
Little is still known about the tiny, money-losing company whose shares exploded 82,000 per cent higher and suddenly made Au, its chief executive officer with an 86 per cent stake, richer on paper than some of the city's tycoons like Li Ka-shing. The fleeting nature of its rip-roaring rally has captivated and mystified observers from the US to Hong Kong. Morning Brew, a popular business account on X, flagged its stock move and wondered: 'Is there something I'm missing?'
Regulators in the US, which closely monitor wild swings in stock prices, might soon be asking the same question, according to experts.

The Financial Industry Regulatory Authority, the watchdog for broker-dealers, has repeatedly said small, cheap stocks are more susceptible to fraud. These companies can be targets for pump-and-dump schemes in which frauds inflate the stock price and quickly sell their shares.
The US Securities and Exchange Commission, meanwhile, has been increasingly wary about companies listed on US exchanges that are based overseas, and Regencell checks both boxes. The regulator on June 4 called on the public to weigh in on whether the agency needed to amend the definition of what's called a foreign private issuer, potentially limiting the number of companies that qualify for special status that lets them avoid filing quarterly financial reports or disclosing when executives buy or sell company shares.
'This is an example of very unusual movements in share prices,' said Richard Harris, founder and chief executive of Port Shelter Investment Management in Hong Kong. 'These movements could certainly trigger interest by investigators.'

Peter Stevens dealerships close in Geelong, Ringwood
Don't miss out on the headlines from News. Followed categories will be added to My News. Two major Victorian motorcycle dealerships closed at the weekend following the collapse of the Melbourne-based Peter Stevens retail group. The stores and showrooms at Peter Stevens Geelong and Ringwood have not been sold and have shut permanently, administrators KordaMentha said. And the City Triumph dealership which closed its West Melbourne showroom earlier this year will also not return. The stores could not be saved although a large portion of the business has been taken over, securing 250 jobs. Dozens of staff at the Peter Stevens sites at Mercer St, Geelong, and Maroondah Highway, Ringwood were only told on Friday of the closure. And customers have been left in the dark over parts and accessories orders. Triumph rider Richard Farrar ordered a $500 part from the Peter Stevens Geelong store but has no idea what's happened to his money. 'They obviously knew they were in trouble when I ordered … and it's bordering on obtaining my money deceptively,'' he said. Peter Stevens went into voluntary administration last month saddled with debt, and last week it emerged that creditors faced losses of over $65m including millions in customer deposits. The company was founded by the Chiodo brothers – Vince, Peter and Steve – in 1970 and grew into a national network of motorcycle stores and dealerships. Flagging motorcycle sales and the cost of living crisis has hit the industry hard in recent years. Some parts of the Peter Stevens group have now been taken over by private company Joe Rascal Group and ASX-listed MotorCycle Holdings. The Joe Rascal Group has will acquire the Harley Heaven stores at Dandenong, Ringwood and Melbourne, as well as Ducati South Melbourne. And Brisbane-based MotorCycle Holdings will take over the Peter Stevens Dandenong and Adelaide sites as well as Savage Motorcycles in Perth and the Harley Heaven dealerships in Sydney, Penrith, Perth and Adelaide. MotorCycle Holdings chief executive Matthew Wiesner said the company would maintain the Peter Stevens and Harley Heaven brands. The deals would mean about 250 employees would keep their jobs, Craig Shepard of KordaMentha said. The administrators said it would assist employees from the closed locations 'during the transition to closure'.

Lift defence spend to show China that Australia means business: Abbott
Australia needs to lift its defence spending so it can be a better ally while pushing back against military actions from China, former prime minister Tony Abbott has urged while expressing hope the economic giant may become the world's most benign superpower. In an address last week to the Australia China Economics Trade and Culture Association, Abbott, who signed the free trade agreement between the two nations just months before losing the prime ministership in 2015, also urged continuing financial links between the countries while cautioning Australia had to broaden its dependence on China. The Albanese government is under pressure from US President Donald Trump to lift defence spending to 3.5 per cent of GDP. Such a sharp lift in spending would cost the budget more than $200 billion by 2035-36. Abbott said Australia had to 'protest strongly' after incidents such as the use of sonar by a Chinese warship to deliberately injure Australian navy divers in 2023, backing that action with increased defence expenditure. 'Australia does need to be militarily stronger, with more ships, more planes, more personnel, more drones and more missiles, so that we can be a better ally and stronger friend,' he said. 'If a stronger military is right for China, and for others, it's right for us too. We have to be in a position to be firm, even with a superpower.' Loading Abbott said while retaining its financial and trading links with China, Australia had to broaden its supply chains. China imposed effective bans on Australian goods worth $20 billion under the Morrison government. 'Australia should keep trading; we should keep accepting students, certainly for the humanities; we should keep accepting highly skilled immigrants, and the dependents of Australian citizens,' he said.
