1. How The Model Works
We employ proprietary machine learning models for each asset to maximise the Sharpe ratio and minimise the drawdowns when trading the name. The model achieves this by examining a number of macro drivers and asset specific factors against the asset’s historical price movements. It is a long-only strategy without leverage.
In interpreting the signal, 1 occurs when the model prefers being “position on” and 0 when preferring “cash”.
There is no “minimum” holding period when the signal shows 1. The model strategy simply holds the asset until the signal turns to 0. This could be after 1 day, 1 week, or longer.
The strategy backtests are based on a buy/ sell the market-open strategy when the signal changes. Returns will be calculated as per below:
When the signal goes from 0 to 1, the strategy buys at the open. The return on the day is the close vs. open.
When the signal goes from 1 to 0, the strategy sells at the open. The return on the day is the open vs. previous close.
When the signal stays from 1 to 1, the return on the day is close vs previous close.
When the signal stays from 0 to 0, the return on the day is 0.
The model will NOT be 100% correct in its market prediction everyday (no model can be - please run away if someone claims this).
The model outputs are not financial advice and there is no guarantee of future performance. Each model is being improved over time, so the below success rates and back-test results are subject to change.
