Japanese conglomerate Panasonic has sold its entire stake in longstanding battery partner Tesla for about ¥400bn ($3.6bn) as it seeks to raise cash to finance its acquisition of US software group Blue Yonder.

The company, which has a $5bn joint battery manufacturing venture with Tesla in Nevada, said the sale would not affect its partnership with the US electric vehicle maker. But Panasonic has made it clear that it wants to reduce its heavy reliance on Tesla and supply batteries to other carmakers as the industry shifts to electric vehicles to reduce its carbon footprint.

Panasonic acquired 1.4m Tesla shares at $21.15 each in 2010 for about $30m. As of March last year, it held shares worth ¥80.9bn, but that stake was reduced to zero by the end of March 2021, according to a filing on the Tokyo stock exchange today.

During those 12 months, Tesla’s stock rose more than six-fold and closed at $679.82 yesterday, valuing the company at $655bn.

3. Fears grow of rising death toll after building collapses in Miami Rescue crews searched through the night for survivors at the site of a collapsed beachfront building in Surfside, north of Miami.

Hedge funds reassess after $12bn meme stock hit Hedge funds that bet on falling share prices are stepping up efforts to spot the next GameStop, after this year’s “meme stock” bonanza left the industry nursing billions of dollars of losses in just six months.

China’s century of revolutions Deng Xiaoping, who became China’s paramount leader in 1978, is rightly credited with a clutch of commercial liberalisations. But his political reforms also targeted the Chinese Communist party’s tragic flaw: that concentrated power, if left unchecked, slides ineluctably into political viciousness and economic stagnation. As China’s ruling party turns 100, James Kynge takes a look back at its history.

Why phoney medicine has lasting allure Humans can’t seem to deal with the idea of a disease for which there is no treatment.
