Thank you for the input. To be more generic, what is sought is a repository of multii-year earnings, ideally averaged, inflated, and used as the denominator in a P/Ex value in a search screener. Other year quantities than 10-years would be good as well; I suggested PE10 since Shiller has created some traction for it rather than other metrics. The presumption is that multi-year data will show more substantial/sustainable track record than single-year data.
Thank you for the cautionary warning. Perhaps you would be comforted in knowing that I care about other metrics - price/book, debt to earnings, free cash flow, revenue and earnings growth rate, industry/political climate, etc. I have screeners for those already. I just would like to upgrade P/E(1) to P/E(>1) or use it in conjunction with P/E(1) AND these other metrics. Or at the very least have a end-of-search check on the stock before investing 5% of net worth into it. (FWIW, as background - until I leave my employer, I am stuck with 401k funds only buying publicly traded things. I would rather not be invested in the general overpriced stock market, and thus mutuals/ETFs. My other option, bonds, will lose as rates rise. So I am somewhat painted into the corner of trying to "pick winners", a self-dubbed "season-trader".)
