STORY: From hope for a brightening global economic outlook, to AI darling Nvidia reporting results... these are the stories to watch for in business and finance in the coming week.

:: Global business activity

May business activity numbers from big economies should reinforce a brighter global economic outlook.

A slow euro area recovery appears underway...U.S. inflation just resumed its downward trend...and China grew faster than expected in Q1.

So, global PMIs should stay in the expansion zone for now. That could easily change as trade tensions rise.

:: Chip time

Nvidia's quarterly results on Wednesday could set the tone for U.S. stock markets.

The chipmaker is expected to report a massive jump in revenue to almost $25 billion...from just over $7 billion a year earlier.

The company may need to meet those lofty expectations and then some to keep its soaring stock price moving higher.

:: Shein and sparkle

There have been plenty of reports on the diminished status of London's stock market.

But that could be about to change, with a string of household names emerging as potential listing contenders.

Chinese fast fashion brand Shein is stepping up preparations for a potential IPO that could be London's largest ever if it's valued at $66 billion.

Diamond firm De Beers is another.

:: Watch, worry, wait

The Reserve Bank of New Zealand is expected to leave rates unchanged on Wednesday for a seventh straight meeting.

It was the first major monetary authority to ease at the start of the global health crisis, and the first to hike in the aftermath.

But sticky inflation and a flatlining economy may keep the bank in the "watch, worry and wait" stance it adopted a year ago.
