Although not quoted directly, the Country music legends Maddie & Tae's influence is writ large over this article examining the upcoming review of US exchanges' circuit breaker mechanisms. 

Essentially, circuit breakers operate to halt trading for a period of time if there is a precipitous movement (up or down, but mostly down) in the price of a security, basket of securities or an index.

The background to the article will be familiar to all - the likely impact of the Covid-19 pandemic on the global economy and individual companies. What jumped out however is the (I am sure intentional) Maddie & Tae reference. For the first time in its history, the New York Stock Exchange closed its trading floor. The NYSE moved to an all-electronic market. 

Stacey Cunningham, president of NYSE, is pleased with the way in which market quality had been maintained but says that a totally electronic market was "not as good as with people involved". This is interesting because (a) the global markets are moving increasingly electronic, (b) a majority of large exchanges have closed their trading floors (or pits) even without the pandemic, (c) a large number of market-makers and liquidity providers trade purely electronically and (d) yet still, the president of the NYSE believes that the "human" element in a market makes the market more resilient and stable.

This may absolutely be correct, but it deserves its own article to examine in detail.
