Seen from this perspective, speculation is the lubricant of the market, which helps attract people into the market place, and also allows the price of any given product to quickly reflect its "true value." In this way it enhances the market's efficiency.
從這種觀點來看，「投機」是一種市場潤滑劑，讓大家更有誘因進入市場，也讓某樣商品的價格能更快地反映其「真實價值」，使市場更有「效率」。
