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 ALGM 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 31, 2023
End date: January 15, 2025
a = 4.7260
b = -0.0011
s = 0.1105
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0011) – 1
= -33.27%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1105) – 1
= 55.57%

Top border of price channel:
Exp(Y566)
= Exp(a + b × X566 + 2 × s)
= Exp(a + b × 824 + 2 × s)
= Exp(4.7260 + -0.0011 × 824 + 2 × 0.1105)
= Exp(4.0339)
= $56.48
Bottom border of price channel:
Exp(Y566)
= Exp(a + b × X566 – 2 × s)
= Exp(a + b × 824 – 2 × s)
= Exp(4.7260 + -0.0011 × 824 – 2 × 0.1105)
= Exp(3.5920)
= $36.31

Top border of price channel:
Exp(Y1,057)
= Exp(a + b × X1,057 + 2 × s)
= Exp(a + b × 1,539 + 2 × s)
= Exp(4.7260 + -0.0011 × 1,539 + 2 × 0.1105)
= Exp(3.2416)
= $25.58
Bottom border of price channel:
Exp(Y1,057)
= Exp(a + b × X1,057 – 2 × s)
= Exp(a + b × 1,539 – 2 × s)
= Exp(4.7260 + -0.0011 × 1,539 – 2 × 0.1105)
= Exp(2.7997)
= $16.44
