Marketmind: Tesla pothole as ECB and GDP awaited

Tesla, the first of the so-called 'Magnificent Seven' U.S. megacap stocks to report fourth-quarter earnings, hit a another pothole overnight even as investors parsed signs of an otherwise brightening economic picture into the new year. A packed diary of events on Thursday, including the first U.S. GDP readout for Q4 and the European Central Bank's latest policy decision, kept world markets buoyed. But with a different story to tell on supply chain issues and competition from China, electric vehicle behemoth Tesla's stock price dropped another 8% overnight as it warned of a sharp slowdown in sales this year.
