Trying to parse through a lot of new data and ratios and have quickly learned that I my mathematical grasp of some of the ratios and how useful they are in different scenarios is far below many of you that post here. I am looking to build a portfolio of defensive equity funds that are primarily large cap domestic but adding in a 20% or so weight to international strategies and I'm trying to decide which ratios might be most useful in analyzing potential investments. right now I am leaning towards the following listed in order of importance:
1) Martin Ratio
2) Downside Deviation - chose this over bear market deviation as it seems easier to compare funds of different categories
3) Ulcer Index
I realize that Martin and Sortino are best used to compare funds that fall into similar categories so I'm not sure how appropriate they are in comparing the domestic to the international strategies. Any help or insights you can give to a newbie would be greatly appreciated.
