Premarket: 6 things to know before the bell

1. Central bankers meet: Federal Reserve chairman Jerome Powell is scheduled to speak at the Economic Policy Symposium in Jackson Hole on Friday.
The speech comes less than a week after President Donald Trump took a swipe at Powell.

In an interview with Reuters, Trump said he was “not thrilled” with the Fed chairman for raising interest rates, arguing the central bank should do more to help the US economy.

Powell was hand-picked by Trump to lead the central bank.

2. Tech summit: Representatives from top US tech companies are expected to meet on Friday in San Francisco to discuss security issues ahead of the 2018 US elections.

According to BuzzFeed, Facebook’s (FB) head of cybersecurity policy, Nathaniel Gleicher, invited representatives from companies including Google (GOOGL) and Microsoft (MSFT).

A study published in the American Journal of Public Health on Thursday suggests Russia’s online meddling went beyond the 2016 US presidential election and into public health, amplifying online debates about vaccines.
