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 BYD 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: February 5, 2021
End date: October 24, 2024

a = 4.0532

b = 0.0000

s = 0.0848

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0000) – 1
= 1.06%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.0848) – 1
= 40.36%

Top border of price channel:

Exp(Y195)
= Exp(a + b × X195 + 2 × s)
= Exp(a + b × 282 + 2 × s)
= Exp(4.0532 + 0.0000 × 282 + 2 × 0.0848)
= Exp(4.2308)
= $68.77

Bottom border of price channel:

Exp(Y195)
= Exp(a + b × X195 – 2 × s)
= Exp(a + b × 282 – 2 × s)
= Exp(4.0532 + 0.0000 × 282 – 2 × 0.0848)
= Exp(3.8918)
= $49.00

October 24, 2024 calculations

Top border of price channel:

Exp(Y1,130)
= Exp(a + b × X1,130 + 2 × s)
= Exp(a + b × 1,639 + 2 × s)
= Exp(4.0532 + 0.0000 × 1,639 + 2 × 0.0848)
= Exp(4.2701)
= $71.53

Bottom border of price channel:

Exp(Y1,130)
= Exp(a + b × X1,130 – 2 × s)
= Exp(a + b × 1,639 – 2 × s)
= Exp(4.0532 + 0.0000 × 1,639 – 2 × 0.0848)
= Exp(3.9311)
= $50.96
