“Watch the Nikkei is you really want to see this in action. Down 711 one day. Up over 500 the next.”
Excellent point. However, a more accurate statistic would be the percentage change.
A daily swing of 500 points in the Dow is cause for concern when the Dow is at 5000, but not so much when it is at 33,000. 10% versus about 1.5%
Point taken - but anything above or below 0.5% is the current market is to be watched - if happening on a regular basis.
