Untested Robo-Advisers Are Becoming a Big Market Risk - Bloomberg View

Assets under Management by Robo-Advisers are not yet that large. But when they are in the hundred of billions it will create the mother of all panics. The programs behind them - in addition to 'sophisticated' quant funds - will all rush to the exit at the same time! Sprinkle a few billions of ETF into the mix and the fun can start! No amount or margin/collateral will be able to cope with the resulting price changes. As I often said in this blog - near instantaneous price moves of 20-25% have to be expected. Remember October 1987! It DID happen, and that was at a time when overall volumes and assets where quite a bit smaller.
