Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of FSLR price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: May 22, 2024
End date: March 28, 2025
a = 8.7085
b = -0.0020
s = 0.0827
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0020) – 1
= -52.60%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0827) – 1
= 39.23%

Top border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 + 2 × s)
= Exp(a + b × 1,513 + 2 × s)
= Exp(8.7085 + -0.0020 × 1,513 + 2 × 0.0827)
= Exp(5.7796)
= $323.64
Bottom border of price channel:
Exp(Y1,043)
= Exp(a + b × X1,043 – 2 × s)
= Exp(a + b × 1,513 – 2 × s)
= Exp(8.7085 + -0.0020 × 1,513 – 2 × 0.0827)
= Exp(5.4486)
= $232.44

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,823 + 2 × s)
= Exp(8.7085 + -0.0020 × 1,823 + 2 × 0.0827)
= Exp(5.1456)
= $171.68
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,823 – 2 × s)
= Exp(8.7085 + -0.0020 × 1,823 – 2 × 0.0827)
= Exp(4.8146)
= $123.30
