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 SRE 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: March 3, 2025
End date: October 8, 2025
a = 2.3503
b = 0.0012
s = 0.0325
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0012) – 1
= 52.43%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0325) – 1
= 13.88%

Top border of price channel:
Exp(Y1,102)
= Exp(a + b × X1,102 + 2 × s)
= Exp(a + b × 1,606 + 2 × s)
= Exp(2.3503 + 0.0012 × 1,606 + 2 × 0.0325)
= Exp(4.2700)
= $71.52
Bottom border of price channel:
Exp(Y1,102)
= Exp(a + b × X1,102 – 2 × s)
= Exp(a + b × 1,606 – 2 × s)
= Exp(2.3503 + 0.0012 × 1,606 – 2 × 0.0325)
= Exp(4.1400)
= $62.80

= Exp(4.5229)
= $92.10
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
