Hi All,
I read a paper today titled "A Quantitative Approach to Tactical Asset Allocation" by Mebane Faber, first published in May 2006. It's basis (implemented below) is a simple Global Asset Allocation Buy &Hold portfolio, against which we should measure the performance of the various iterations of his Global Tactical Asset Allocation Models (to follow).
As expected for a global diversified portfolio (B&H) it yields a sharpe ratio in the order of 0.4 (owning individual "Risky" assets usually returns a sharpe around 0.2). It appeasrs the previous decade has been quite extraordinary for the S&P, with a sharpe=0.7!
This is my first attempt (as a hobbyist programmer) at an algorithm on QuantConnect, using the structure provided in the AlgorithmFramework, so questions, comments & criticisms are all welcome!

Hi Mark,
Great first attempt! Here are a few small improvements to consider:

Thanks Derek!
Is this what you mean by using list comprehension and insight duration (Refer attached backtest)?
What do you mean when you say to keep Initialize "dry"?
Also, I couldnt get the daterules/timerules function to work for me with PC.... eg,
self.SetPortfolioConstruction(EqualWeightingPortfolioConstructionModel(self.DateRules.MonthStart(), self.TimeRules.AfterMarketOpen('SPY', 5)) )
Can you see my obvious error?
Many Thanks,
Mark

Hi Mark,
Great job! This is exactly what I mean by using list comprehension and changing the insight duration.
"DRY" is an acronym for "Don't Repeat Yourself". By using list comprehension in Initialize like this, we type `Symbol.Create(...)` once instead of 5 times.
The EqualWeightingPortfolioConstructionModel constructor can't take both a DateRules and TimeRules parameter. Instead, we can accomplish monthly rebalancing after the open by passing the construct a function.
self.SetPortfolioConstruction(EqualWeightingPortfolioConstructionModel(self.RebalanceFunction)) self.lastRebalanceMonth = -1We then define the rebalancing function as
def RebalanceFunction(self, time): if self.Time.hour == 9 and self.Time.minute == 31 and self.Time.month != self.lastRebalanceMonth: self.lastRebalanceMonth = self.Time.month return timeSee the attached algorithm for a working solution.
Best,
