Modern bubbles - markets rigged to succeed for some people?
People sitting atop bubbles with a parachute to hand descend unscathed from market-crashes.
Referred to are operators clustering within market centres such as Wall Street and the City of London. Some have secure incomes from acting as middlemen between buyers and sellers of stock. These have incentive to talk-up values when their transaction fees are percentage based. Others working under fixed fees benefit too by encouraging a frenzy of buying.
Financiers sitting on piles of a stock with a view to a huge capital gain do bear some risk, but it needs only be minor. When holding stocks which have doubled or tripled in nominal value, they may anticipate a small paper loss at the outset of a bursting bubble or broader market crash. Unlike most private investors and managers of small pension funds, operators at a financial nexus benefit from three things.
First, active participation in the flow of information concerning 'insider' knowledge. These people recognise tremors indicative of seismic shock to come.
Second, algorithmic trading enables rapid pre-prepared responses to tremors. Physical location close to a trading centre/exchange offers an edge over location further away; a simple consequence of transmission times along cables. Better yet, to have a direct connection to an exchange to cutout circuitous routes via ISPs.
Third, exclusion of almost all private investors and their advisors from timely public information about stock prices. Without subscription to an exchange, information flow is deliberately retarded by fifteen minutes in the UK and similarly elsewhere.
Thereby, markets are rigged. Big players respond immediately to tremors. If prices have gone down, but settled, they can buy back-in advantageously. Should a bubble be bursting, they will bear some loss on the previous notional value of their stock, but they will have factored that in as something to anticipate and to weather.
Few people raise complaint about the two obviously remediable blights of algorithmic trading and imposed delays on information passage to 'outsiders'. Each is a preventable scandal. Computer assisted trading is here to stay; however, it should have built-in, unavoidable, delays emulating those when trading intermediaries thronged exchange trading floors. Delays reduce the risk of out of control feedback loops occurring as algorithm speaks unto algorithm. Analogously, social media platforms such as Twatter would be much less prone to inane 'viral' episodes if the mechanism of making responses contained unavoidable delays. As an aside, it's more likely that social media operators would offer subscription payers shorter delays so that their responses gain immediate prominence.
The advent of the Internet makes it inexcusable for exchanges to delay output of the activities for most people. Privately owned, exchanges may be, but they are public resources. Real time information can be entered onto the Internet at negligible cost.
Unfortunately, banking and finance, especially since "deregulation" are laws unto themselves (as indeed is the City of London literally). Of course, the true underlying rot - fractional reserve banking - spans centuries.
If/when AI mania collapses, one may be sure of 'little people', via private investment or through pension funds, bearing the consequences.
