Interesting to note that the fall by the ASX from 81.88 to 78.5 (a difference of $3.88) was 4.1% in the two days before the ASX posted on the ISX's site (but not on their own) the ISX's announcement of the court case, just outside the guidelines on whether the ASX should have made the announcement to the shareholders - and, by the way n00bmasta, this was NOT in line with the S&P200 at that time.
Also interesting to note that for the time that the ASX was criticising ISX for not disclosing customer names (see 18 Nov, 2019 - answers to ASX, question 3 A-D), the market had not wandered more than from 15 cents to 16.5 cents (a difference of a cent and half). Sadly, however a 1.5 cent difference for a penny stock at 15 - 16.5 cents signifies a > ~9% difference. This seems a tad bit unfair to me to use the same standards for a multi-dollar and a penny stock.
