Let's analyze what's taken place over the past 24 hours.


As the US stock market opened on Monday, Chinese-made expert system (AI) model DeepSeek stunned financiers and sank some tech stocks.


Chip-making huge Nvidia shed almost $600bn (_ 482bn) of its market price - the most significant one-day loss in US history. Other tech stocks such as Microsoft, Google-owner Alphabet and Dell Technologies also sank - albeit by smaller margins.


A day later, it appears somewhat calmer. Nvidia shares had a mixed start as the US stock exchange opened, business press reporter Nick Edser informs us. After flip-flopping a little in the very first couple of minutes, its value recovered - standing 1.3% greater.


In Asia, the markets in Taiwan, China and South Korea have actually closed for the Lunar New Year. But by the end of Tuesday's trading, Tokyo's Nikkei 225 index had actually dropped 1.39%, while Hong Kon's Hang Seng made a small 0.14% gain.
