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 RUSHA 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: November 24, 2020
End date: December 13, 2023
a = 3.2272
b = 0.0003
s = 0.0723
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0003) – 1
= 12.36%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0723) – 1
= 33.51%

Top border of price channel:
Exp(Y165)
= Exp(a + b × X165 + 2 × s)
= Exp(a + b × 237 + 2 × s)
= Exp(3.2272 + 0.0003 × 237 + 2 × 0.0723)
= Exp(3.4474)
= $31.42
Bottom border of price channel:
Exp(Y165)
= Exp(a + b × X165 – 2 × s)
= Exp(a + b × 237 – 2 × s)
= Exp(3.2272 + 0.0003 × 237 – 2 × 0.0723)
= Exp(3.1584)
= $23.53

Exp(Y932)
= Exp(a + b × X932 + 2 × s)
= Exp(a + b × 1,351 + 2 × s)
= Exp(3.2272 + 0.0003 × 1,351 + 2 × 0.0723)
= Exp(3.8031)
= $44.84
Bottom border of price channel:
Exp(Y932)
= Exp(a + b × X932 – 2 × s)
= Exp(a + b × 1,351 – 2 × s)
= Exp(3.2272 + 0.0003 × 1,351 – 2 × 0.0723)
= Exp(3.5141)
