What about another common tactic of letting winners run and selling losers? Let's experiment by selling losers after different time periods. Stocks sold won't be bought again.
Strangely, this does not seem to be correct for this portfolio. However, at least in part this is due to the fact that more funds are freed up, and therefore, more purchases were made in the last 1-2 years of the tests. These have not yet had enough time to make a profit and dragged down performance of previous trades. So, I think selling losers makes sense, with 3+ years sounding about right.
I could go on for a while, but let's do just one more. As funds are limited, and there's no way where a bottom, or top, will be, would it make sense to restrict purchase frequency?
There are, of course, an unlimited number of possibilities and strategies, so I'll stop here. The statistic I am most curious about at the moment is how many people read all the way up to here.
P/B is of course only one ratio of many, and not one I would exclusively use. I also find it most useful to analyse individual trades in the backtest, more so than the end result.
So back to the original questions, is value investing dead? No, I think it clearly still works. But I do not think a fully automated approach works. Buying things on the cheap is the right thing to do, but stock selection/exclusion and portfolio management are just as, if not more important.
To show off, I've recorded a video of the software in use:

If anyone found this of interest, and would like for me to post similar things in the future, please let me know. Even if you are a lurker that doesn't usually post, a simple "Yep" would be much appreciated.
Questions/Suggestions/Requests?
Thanks for indulging me.
