The quote by Isaac Newton, “What goes up must come down”, is a simple and straightforward observation about the force of gravity.  It highlights the universal physical principle that any object propelled in the air will eventually succumb to the gravitational pull of the earth and return to the ground.  In energy, the quote reminds us of how the supply/demand market fundamentals deliver volatility in the front end of the forward curve but with little tweaks and the appropriate price signal, order eventually gets restored until some other factors start to percolate.
