The behavior i observed regarding Natural Gas (NG) prices over the past two years, showing a pattern of positive returns in Q1 and Q2 and negative returns in Q3 and Q4, can be explained by several factors that influence the energy market, particularly the seasonal nature of natural gas demand.

Key Factors:
Seasonal Demand:

Q1 and Q2 (Winter and Early Spring): Natural gas is in high demand during the colder months, especially in North America and Europe. The need for heating increases, which drives up demand for natural gas, leading to price increases. This is why the price generally rises during the first half of the year.
Q3 and Q4 (Late Summer and Fall): Demand for natural gas decreases as warmer weather reduces the need for heating. In addition, Q3 often coincides with lower energy consumption due to milder weather, while Q4 may show some price declines before winter demand picks up again in late Q4.
Supply Factors:

The supply of natural gas may remain stable or even increase in warmer months, with less demand pushing prices down in Q3 and Q4. This dynamic causes prices to retreat.
Hurricane Season (Q3):

Natural gas production, particularly in the U.S., can be affected by hurricanes in Q3. Disruptions may cause temporary spikes, but if supply isn't significantly reduced, the general trend remains bearish in this quarter.
Storage Injections (Q2-Q3):

During Q2 and Q3, natural gas is often injected into storage for use during the winter months. While this may support prices slightly, it typically doesn't offset the general lower demand, keeping prices under pressure.
Observed Patterns:
Q1 & Q2 (Positive Returns): Cold weather and increased demand for heating fuel drive natural gas prices higher, resulting in positive returns.
Q3 & Q4 (Negative Returns): Warm weather reduces demand, and prices fall as supply exceeds immediate demand for heating.
This recurring pattern is a result of the highly seasonal nature of natural gas usage, and traders often anticipate and plan for these price movements when making decisions in the natural gas futures market.
