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 ACLS 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 25, 2023
End date: June 4, 2024
a = 7.3975
b = -0.0017
s = 0.0786
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0017) – 1
= -45.87%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0786) – 1
= 36.93%

Top border of price channel:
Exp(Y883)
= Exp(a + b × X883 + 2 × s)
= Exp(a + b × 1,282 + 2 × s)
= Exp(7.3975 + -0.0017 × 1,282 + 2 × 0.0786)
= Exp(5.3986)
= $221.09
Bottom border of price channel:
Exp(Y883)
= Exp(a + b × X883 – 2 × s)
= Exp(a + b × 1,282 – 2 × s)
= Exp(7.3975 + -0.0017 × 1,282 – 2 × 0.0786)
= Exp(5.0843)
= $161.46

Top border of price channel:
Exp(Y1,140)
= Exp(a + b × X1,140 + 2 × s)
= Exp(a + b × 1,658 + 2 × s)
= Exp(7.3975 + -0.0017 × 1,658 + 2 × 0.0786)
= Exp(4.7662)
= $117.47
Bottom border of price channel:
Exp(Y1,140)
= Exp(a + b × X1,140 – 2 × s)
= Exp(a + b × 1,658 – 2 × s)
= Exp(7.3975 + -0.0017 × 1,658 – 2 × 0.0786)
= Exp(4.4519)
= $85.79
