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
Primary Trend
Start date: January 22, 2024
End date: December 3, 2025
a = 3.6049
b = 0.0014
s = 0.1747
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0014) – 1
= 63.90%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1747) – 1
= 101.16%

Top border of price channel:
Exp(Y785)
= Exp(a + b × X785 + 2 × s)
= Exp(a + b × 1,144 + 2 × s)
= Exp(3.6049 + 0.0014 × 1,144 + 2 × 0.1747)
= Exp(5.5030)
= $245.42
Bottom border of price channel:
Exp(Y785)
= Exp(a + b × X785 – 2 × s)
= Exp(a + b × 1,144 – 2 × s)
= Exp(3.6049 + 0.0014 × 1,144 – 2 × 0.1747)
= Exp(4.8040)
= $122.00
