Orthogonal Spread Analysis

Here we apply an orthogonal regression (also known as total least squares) to both price series. We are interested in some key statistical properties (like β, ...) and in analysing orthogonal residuals:

TLS: AMGN*(t) = β * PBYI*(t) + α
Regression coefficient α:
152.461921
Regression coefficient β:
0.032187
Standard Deviation (σ):
4.221447
ADF test of residuals (p-value):
0.0383
95% confidence: residuals don't contain a unit root
99% confidence: residuals seem to contain a unit root
Mean Reversion Coefficient (MRC):
-0.139026
Half-life:
4.99
Skewness:
0.1664
Kurtosis:
-0.5144
Doornik-Hansen normality test (p-value):
0.3641
Normality test failed at 95% confidence
0.1379
Normality test failed at 95% confidence

Cointegration Analysis

In this section, Engle-Granger cointegration test is performed using OLS regression method in both directions. Residuals of the regression are plotted and analyzed further:

Profit Analysis

Profit analysis is a set of backtests performed using multiple pair trading models over significant portion of parameter space. Backtest results are displayed in a form of scatter plot. In addition, you can see aggregated statistics in the left panel. All backtests are performed using 100% margin (leverage 1:1). This is the profit analysis where backtested strategies are allowed to open both long and short positions:

Disclaimer: Backtested, simulated or hypothetical performance results have certain inherent limitations. Unlike the results shown in an actual performance record, these results do not represent actual trading. There are numerous factors related to the stock market in general and to the implementation of any stock market timing program, which cannot be fully accounted for in the preparation of hypothetical performance results. The backtested results listed here do not take into consideration slippage, fees, taxes, or dividends and interest earned on cash positions. These factors would affect actual trading results. Simulated, backtested or hypothetical stock trading systems in general are also subject to the fact that they are designed with the benefit of hindsight. Backtested performance does not represent actual performance and should not be interpreted as an indication of such performance. No representation is being made that you will or is likely to achieve profits or losses similar to these being shown.
