However, new traders generally take portfolio design too lightly. It is simply not a matter of putting all the systems you can within an account, put a very high risk level and hope for the best. No, it is not about that and that strategy usually leads to account wipeouts and other such problems. You need to make up your portfolio with a very clear plan and knowledge of what you will do when certain scenarios present themselves.
First of all, each separate system must have its OWN risk projections and its own worst case scenario (the point where the system has simply become to risky to continue trading). You need to know into how much draw down each system will go because each draw down will contribute to the overall loses of the account. Second – and most important – you need to calculate your portfolio risk accurately. To do this you need to calculate the sum of all the projected draw downs and have this as your worst-case portfolio scenario.
In the end each system will be able to reach twice its historically worst perfoming point (the worst case individual scenario) and the portfolio’s worst scenario will be the addition of all the system’s historical maximum risk levels. In the end, systems have a flexibility to reach higher than expected draw downs (which are likely going to happen in the future) and the portfolio will be able to reach larger than expected risk additions since its “worst point” is an addition of draw down. This in turn means that portfolios have a lower risk thresehold than the systems, mainly because they need to reduce risk through diversification -if this doesn’t happen – the portfolio is simply not working.
In the end doing this analysis will ensure that you have CLEAR targets for your risk and clear “stops” in your account’s loses (since you know when to stop individual systems or the whole portfolio). One of the most important things in trading is to have a plan and trading a portfolio with a previous risk analysis is VITAL for survival. Of course, making sure that each one of the systems used is long term profitable is also of extreme importance and something which will make the success of a trading portfolio much more likely.
