Hi, for Nasdaq 100 and Dow 30 strategies, the backtests take into account index past and current constituents (avoiding Survivorship Bias)? Thanks
For dow30 this would not be a big problem, but it would be for nasdaq100. I would like to know the opinion of the administrators of the site. Thank you
We are well aware of survivorship bias but both the Nasdaq 100 and Dow30 backtests do not take it into account. That means that long term backtested are optimistic. On the other hand the Nasdaq 100 has been ‘live’ for a few years now and has gathered historical performance data that is indeed survivorship-bias free.
Alimcor – you seem high maintenance for a basic membership man. If you’re so resourceful why don’t you backrest it. Just asking no offense.
You could do that using Norgate data and Amibroker. Unfortunately it is not that simple to input the data to QuantTrader, our proprietary software since we would have to create a whole ‘subsystem’ from scratch just to handle that data. It’s probably easier to create the N100 startegy in Amibroker and run the backtest there. But this too is complicated and inefficient since the N100 strategy (and most LI strategies) are not a good match for the AB ‘vector type’ logic. We have run our own private tests and our conclusion is that it’s not worth the effort. We have survivorship-free out-of-sample data since July 2015 when N100 went live that seem to validate the logic.
