What the pattern says about natural gas
September has had the highest average monthly change at +8.5%, and April has finished higher most often, in 69% of years. January has been the weakest on average at −5.2%, and July has been up least often at 31% of years.
Averages hide wide differences. In any month the result can be far above or below the average, and most calendar months show only a small edge over a coin flip. Interest rates, currencies, supply and news usually matter much more than the calendar, so use this as background and not as a reason to buy or sell.
