"The point is the factual basis of determining excessive speculation needs to be based on something that is concrete, not an aftereffect but something that is concrete."

"Everything seems to be rigged for an upward bias."

"Excessive speculation leads to markedly increased volatility, what you should expect some market force on real supply and demand to have some influence on."
