I'm always concerned about how these products deal with survivorship bias. Anyone look into this one?

I wasn't refering to the market timing scheme. I was more interested in whether the 40+ years of daily data really does exist and if it does, is it any use to all those brilliant people out there doing all the backtesting and data compiling that is making all of us rich.
Hmmmmm....maybe I should just go back to lurking on the beach and making a bunch more money off the already awesome robust screens we have.

It could be useful. But there are often problems with these databases. One of the problems we've discussed on this board before is "survivorship bias." These databases are often missing stocks of companies that have gone out of business. As you might imagine, this can dramatically skew results. The reason we lean toward Value Line is that its database is being created in "real time" and thus has no survivorship bias.

Of course, Value Line still manages to screw things up. Stocks change ticker symbols, stocks have splits and reverse-splits, and companies buy and spin-off companies. Stocks pay dividends. Stocks do all kinds of weird friggin things.

Heck, it's hard to put together a Dow database, and the Dow 30 stocks are, well, blue-chips.

It's a nightmare. Unless someone who has experience with these things looks at the database and says, "Wow, they did it right!" I'm going to be sceptical.

That's why databases like CompuStat, CRSP, etc. cost zillions of dollars to subscribe to. Well, one reason.

My own experience of Rueters ($35/month) was horrific. After screening the data for sudden drops > 30% and comparing with data from Yahoo, I found about a third of the stocks contained unrecorded splits or dividends. I've also read comparisons of vendors that rate Rueters pretty well in terms of quality. Hmmmm.
Hard to believe anything less than CRSP or Compustat will do.
