Electric car maker Tesla had its best day on the market in over a decade on Thursday due to the company's surprisingly solid results.

Shares ended Thursday's session up almost 23%, giving Tesla a market valuation of $836 billion (£644 billion). CEO Elon Musk's net worth rose by $33.5 billion, extending his lead as the world's richest person, according to the Bloomberg Billionaires Index.

Tesla kicked off its “Magnificent Seven” results on Wednesday, posting record-breaking adjusted earnings per share and higher gross margins.

Adjusted earnings per share of $0.72 were above expectations of $0.60, with adjusted net income of $2.5 billion and free cash flow of $2.9 billion.

Tesla's closely watched gross margin came in at 19.8%, well above the expected 16.8%.

Additionally, Tesla said preparations are still underway to launch its cheaper models in the first half of next year.

Musk also said in a conference call that Tesla's volume growth could be between 20% and 30% next year.

Bank Lloyds reported a slight decline in profits in the third quarter, but still beat estimates and reiterated its forecast for the full year.

Profit before tax was 1.823 billion pounds ($2.36 billion) in the third quarter, down 2% from the same period last year.

However, according to the bank, this amount was above consensus estimates of 1.622 billion pounds.

In a conference call after the results were released on Wednesday, Lloyds group chief financial officer William Chalmers said the bank had “continued to see increased confidence in customer activity”.

Looking ahead to next week's autumn budget, Chalmers said the bank was expecting some “clarity” from the statement

“We also hope that the Budget will be a growth-enhancing event,” he added.

Shares rose following the earnings release on Wednesday but were flat Friday morning. Lloyds was the first major British bank to report this week, followed by Barclays (BARC.L) and NatWest (NWG.L), which reported strong profit growth.

Shares of Capri Holdings, the parent company of Michael Kors and Jimmy Choo, plunged 45% in after-hours trading on Thursday after a U.S. judge ruled against its pending $8.5 billion merger with Coach owner Tapestry (TPR ) had blocked.

In a court filing obtained by Yahoo Finance, U.S. District Judge Jennifer Rochon ruled that “antitrust has become fashionable” and argued that a merger between the two fashion groups “will significantly reduce competition in the accessible luxury handbag market.”
