Dr Ernie Chan Answers to rank or weight a long or short of out this market sector according to Yahoo Finance

Question was asked at:

https://quantlabs.net/blog/2015/01/how-would-rank-or-weight-a-long-or-short-of-out-this-market-sector-according-to-yahoo-finance/

His answer was:

Hi Bryan,
There are various methods of including a subset of predictive
variables for returns prediction.
You can try stepwise regression, which picks successively the most
predictive variable in a linear regression, and stops when an
additional variable does improve R^2.
You can also try a regression tree, with a similar principle.
Both are available from Matlab Statistics toolbox.
Hope this helps!
Best,
Ernie
