Rebalancing with 1/N algorithm

Hi All,

I am totally new here, I dont know where to start and end. I have to do the following assignment by tomorrow. Can anyone guide me or help with it. You can reach me at : swaroopkpydisetty@gmail.com if you have any further questions.

I want to implement a 1/N algorithm where you distribute the funds available ( say $1,000,000) in buying the stocks (some 100 different varieties, so every stock should have $10,000 worth: for example Facebook stock price is $40 and google’s $50, we should have 250 of FB and 200 of google) equally from available that are being traded. I need to rebalance the portfolio by maintaining the stock worth to 1/N of the total funds after every month/ year. Whenever the share price increases decreases, we need to rebalance the total stocks without violating the 1/N ratio of that particular stock. We also need to implement the same once at the month of every month and at the end of every year too.

Thank you very much.

Implement 1/N rebalancing algorithm is incredibly easy with QuantConnect, because the hardest part (computing the shares we need to buy/sell to achieve the balance) is automatically done by the SetHoldings helper (please checkout the docs, under the Trading and Orders section, for more information):

// Set fixed percentages of known tickers:
SetHoldings("IBM", 0.25);
SetHoldings("GOOG", 0.25);
SetHoldings("AAPL", 0.25);
SetHoldings("MSFT", 0.25);

// Or set portfolio to equal weighting of all securities:
var weighting = 1m / Securities.Count;
foreach(var security in Securities.Values) {
SetHoldings(security.Symbol, weighting);
}

We just need to verify whether we are entering on a new month to perform the rebalancing.

Thank you Alexandre, this works wonderfully and this is what I am looking for. I have one question. How do I get the list of all the available stocks in the platform and use them in my algo?

I have tried to copy paste all the symbols, is there a better way to do this?

@Swaroop - check out the Universes section of the documentation and this example. Generally you should never list symbols but instead select a universe of stocks based on some criteria.
