It was a double whammy. The inability to figure out the financial influence of coronavirus on corporate earnings was lousy sufficient. Toss in a sudden selling price war among the Russians and the Saudis and you have the makings of an unattractive working day, and a especially hideous open up. 

Energy stocks ended up clobbered. Exxon Mobil fell 12%, its lowest near given that 2004.

The poster baby for the day’s woes, nevertheless, was probably Halliburton, which experienced a few buying and selling halts in fewer than an hour right after the open up. One particular was triggered when the full market place was shut for 15 minutes at 9:33 a.m. ET, and two specific investing halts hit at 10 a.m. and 10:22 a.m. Both stopped investing in the inventory for an supplemental five minutes.  Halliburton shut down 37%.

 There was 1 winner, at minimum. The current market-vast circuit breakers on their own.

They had been examined for the initially time due to the fact they were substantially revamped much more than a decade back, and it was only the 2nd time they kicked in given that 1997. 

Inside of a few minutes of the industry open up at 9:33 a.m., technique-huge circuit breakers kicked in when the S&P 500 dropped 7%, triggering a 15-minute buying and selling halt of all stocks.  

This was the first time that the fashionable circuit breaker had kicked in, and it did its work — to pause the industry and produce liquidity. 

The purpose of the circuit breakers was not to alter any fundamental story for why the markets may well be down — in this case, coronavirus and oil worries. It was to pause the marketplace so that traders can give much more liquidity. 

Circuit breakers, in a sense, are profoundly anti-significant frequency trading:  They are meant to empower traders to catch their breath and determine out how substantially extra they may want to purchase and market.  

In that feeling, the technique worked perfectly:  Shares rallied modestly after the markets re-opened at 10:49 a.m. as traders took benefit of the reduce costs.  Market place volatility — as measured by the CBOE Volatility Index — also declined, nevertheless it remained in close proximity to the highest concentrations considering the fact that the economical disaster. 

In the end, the procedure failed to reverse the sector slide, but it at minimum place a modest brake on a very unsightly get started.
