Well in terms of the tech industry, there is a on going trend that many unprofitable tech companies are rushing their IPOs everywhere on the stock market and this is perhaps due to many possible actions such as tech regulation or many investors won't fund startups because of the established competition, profitability concerns, etc.

The uncertainty of the US-China trade war is making many investors concerned about the economy and the UK is still playing Deal or No Deal with leaving the EU after 3 years of 'negotiations'. If the UK leaves without a deal, I won't be surprised if this causes a recession, at least in the UK. But the trade war, the IPO rush and possible regulation is perhaps an indicator of a global one in the tech industry.
