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 CORT 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: January 22, 2024
End date: February 28, 2025
a = -1.1383
b = 0.0030
s = 0.0842
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0030) – 1
= 202.42%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0842) – 1
= 40.06%

Top border of price channel:
Exp(Y938)
= Exp(a + b × X938 + 2 × s)
= Exp(a + b × 1,363 + 2 × s)
= Exp(-1.1383 + 0.0030 × 1,363 + 2 × 0.0842)
= Exp(3.1626)
= $23.63
Bottom border of price channel:
Exp(Y938)
= Exp(a + b × X938 – 2 × s)
= Exp(a + b × 1,363 – 2 × s)
= Exp(-1.1383 + 0.0030 × 1,363 – 2 × 0.0842)
= Exp(2.8257)
= $16.87

= Exp(a + b × 1,766 + 2 × s)
= Exp(-1.1383 + 0.0030 × 1,766 + 2 × 0.0842)
= Exp(4.3845)
= $80.20
Bottom border of price channel:
Exp(Y1,215)
= Exp(a + b × X1,215 – 2 × s)
= Exp(a + b × 1,766 – 2 × s)
= Exp(-1.1383 + 0.0030 × 1,766 – 2 × 0.0842)
= Exp(4.0476)
