Article 62 Significance of Unusual Market Action

Where unusual market action in price movement, trading activity, or both occurs without any apparent publicly available information which would account for the action, it may signify trading by persons who are acting either on unannounced material information, or on a rumour or report, whether true or false, about the issuer. Most often of course, unusual market activity may not be traceable either to insider trading or to a rumour or report. Nevertheless, the market action itself may be misleading to investors, who are likely to assume that a sudden and appreciable change in the price of an issuer's securities must reflect a parallel change in its business or prospects. Similarly, unusual trading volume, even when not accompanied by a significant change in price, tends to encourage rumours and give rise to excessive speculative trading activity, which may be unrelated to actual developments in the issuer's affairs.
