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 TSLA 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

a = 2.1740
b = 0.0024
s = 0.1533
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0024) – 1
= 138.12%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1533) – 1
= 84.67%

Exp(Y818)
= Exp(a + b × X818 + 2 × s)
= Exp(a + b × 1,190 + 2 × s)
= Exp(2.1740 + 0.0024 × 1,190 + 2 × 0.1533)
= Exp(5.3094)
= $202.22
Bottom border of price channel:
Exp(Y818)
= Exp(a + b × X818 – 2 × s)
= Exp(a + b × 1,190 – 2 × s)
= Exp(2.1740 + 0.0024 × 1,190 – 2 × 0.1533)
= Exp(4.6960)
= $109.51
