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 LGIH 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: March 5, 2021
End date: November 29, 2022

a = 5.7712

b = -0.0012

s = 0.1079

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × -0.0012) – 1
= -35.79%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1079) – 1
= 53.95%

March 5, 2021 calculations

Top border of price channel:

Exp(Y322)
= Exp(a + b × X322 + 2 × s)
= Exp(a + b × 470 + 2 × s)
= Exp(5.7712 + -0.0012 × 470 + 2 × 0.1079)
= Exp(5.4165)
= $225.10

Bottom border of price channel:

Exp(Y322)
= Exp(a + b × X322 – 2 × s)
= Exp(a + b × 470 – 2 × s)
= Exp(5.7712 + -0.0012 × 470 – 2 × 0.1079)
= Exp(4.9851)
= $146.21

November 29, 2022 calculations

Top border of price channel:

Exp(Y760)
= Exp(a + b × X760 + 2 × s)
= Exp(a + b × 1,104 + 2 × s)
= Exp(5.7712 + -0.0012 × 1,104 + 2 × 0.1079)
= Exp(4.6471)
= $104.28

Bottom border of price channel:

Exp(Y760)
= Exp(a + b × X760 – 2 × s)
= Exp(a + b × 1,104 – 2 × s)
= Exp(5.7712 + -0.0012 × 1,104 – 2 × 0.1079)
= Exp(4.2156)
= $67.74

a = 4.4732

b = 0.0001

s = 0.1240

Annual growth rate:

Exp(365 × b) – 1
= Exp(365 × 0.0001) – 1
= 5.23%

Price channel spread:

Exp(4 × s) – 1
= Exp(4 × 0.1240) – 1
= 64.20%

March 23, 2022 calculations

Top border of price channel:

Exp(Y587)
= Exp(a + b × X587 + 2 × s)
= Exp(a + b × 853 + 2 × s)
= Exp(4.4732 + 0.0001 × 853 + 2 × 0.1240)
= Exp(4.8402)
= $126.50

Bottom border of price channel:

Exp(Y587)
= Exp(a + b × X587 – 2 × s)
= Exp(a + b × 853 – 2 × s)
= Exp(4.4732 + 0.0001 × 853 – 2 × 0.1240)
= Exp(4.3443)
= $77.04

November 20, 2024 calculations

Top border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 + 2 × s)
= Exp(a + b × 1,826 + 2 × s)
= Exp(4.4732 + 0.0001 × 1,826 + 2 × 0.1240)
= Exp(4.9761)
= $144.90

Bottom border of price channel:

Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,826 – 2 × s)
