What to watch for today

Are Japanese stocks setting the tone for a slump? The benchmark Nikkei 225 has dropped by 3.9% and counting, following its worst day since 2013 yesterday, on concerns about banking stocks. Another bad day in Japan could create more pessimism in European markets.

Janet Yellen in the spotlight. The Federal Reserve chair will take two days of questions from US lawmakers; investors hope she can help calm the volatile global economy.

Twitter’s moment of truth. The company’s quarterly results may be the most important in its history, following a period of turmoil and stock declines. Growth numbers have been anemic and users have complained about impending changes to the Twitter timeline.

While you were sleeping

Donald Trump and Bernie Sanders won New Hampshire. The billionaire real estate mogul has so far raked in the votes from the US’s first presidential primary, putting Ohio governor John Kasich second. Sanders trounced Hillary Clinton with 60% of the votes to her 40%. Around 80% of districts have reported results (paywall).

China reported its first case of the Zika virus. A 34-year-old man contracted the disease in South America and returned home via Hong Kong and Shenzhen after displaying symptoms. Authorities are playing down concerns of contagion because of the cold weather there.

Deutsche Bank is planning an emergency buyback. Germany’s biggest lender is considering buying back billions of euros worth of senior bonds, according to the Financial Times (paywall). The aim is to prop up the value of the bank’s securities and share price, which have plummeted since the beginning of the year.

The US said North Korea is preparing more nukes. US intelligence chief James Clapper said Pyongyang has expanded plutonium production and is committed to building a long-range missile that could pose a “direct threat” to the United States.

Record Disney earnings couldn’t stop its share price falling. The entertainment company reported a net income of $2.9 billion in the three months ending January, from $2.2 billion a year earlier. But concerns of its cable TV relevance, in an age of online viewing, sent shares down 3.5%.

Asahi issued a disappointing outlook. The Japanese beer giant said sales will remain largely flat in 2016, but that net income will be around 10% lower than analysts expected, at 80 billion yen ($697.4 million). The company will continue to seek growth through mergers and acquisitions.
