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 ACHC 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 10, 2024
End date: January 30, 2026
a = 7.4271
b = -0.0026
s = 0.1562
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0026) – 1
= -61.54%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1562) – 1
= 86.81%

Top border of price channel:
Exp(Y739)
= Exp(a + b × X739 + 2 × s)
= Exp(a + b × 1,072 + 2 × s)
= Exp(7.4271 + -0.0026 × 1,072 + 2 × 0.1562)
= Exp(4.9331)
= $138.81
Bottom border of price channel:
Exp(Y739)
= Exp(a + b × X739 – 2 × s)
= Exp(a + b × 1,072 – 2 × s)
= Exp(7.4271 + -0.0026 × 1,072 – 2 × 0.1562)
= Exp(4.3082)
= $74.31

= $19.43
Bottom border of price channel:
Exp(Y1,254)
= Exp(a + b × X1,254 – 2 × s)
