Is the phenomenon described by Elliot Wave Theory that shows stock prices moving in regular repeating patterns being manipulated to happen, is it solely connected to human consciousness and consequences, or is there some other explanation?

This is a phenomenon related to human consciousness and is not sinister in basic terms, although there is nothing to prevent the interlopers from making a manipulation that causes a departure from the norm by interrupting a particular wave pattern and replacing it with a new pattern moving in the opposite direction. But knowing the trends and the basic nature of things, the interlopers will arrange to mimic the pattern, following the new change in direction, so that it will then begin to conform with expectations of the cyclic nature and all will appear natural and not an artificial intervention. There may be something inexplicable about a sudden direction change but this happens frequently with the markets as a whole in addition to the many individual holdings that can move for any number of reasons—either in sympathy with a sector that is under change in sentiment, or particular news about a company or organization that can be expected to affect the value of the goods or services of a particular company. All such influences will factor in the day-to-day fluctuations and are not necessarily sinister unless there is news management specifically for that purpose.
