Zacks Backtesting Yields Over %50

Quote from misterno:

I have been using Zacks research Wizard and I pay close to 2K for this service. (backtesting goes back to 1999) I just started like a year ago and after several months of playing around with it, I managed to create screens that yields over 40-50%. Of course this is a compounded return thus may not be accurate in real life. (buying monday and selling friday ONLY 1 STOCK)

50% seems illogical to me, I mean c'omoon it can not be this easy. I would like to hear what other users are saying. Anyone using research wizard here? Also, if I can create screens that yields over %50, how come the creator of the program Kevin Matras mentions screens for 50% all the time. I mean with all those years of experience, he should know better. Don't you think so?

What am I missing here? I want to share ideas with people using Research Wizard. Let's share ideas and strategies here.

If these strategies would be working so well, Zacks would not be selling their service, rather be betting the farm on it. There is no easy and sure of making anything over the risk free rate...
 
Well, not exactly.

They are not selling a system they are selling a data filtering database as is Reuters. Except, Reuters clients are hedge funds and other institutional clients not retail.

I'll agree that the quality of Zack's is way lower than its institutional counterparts but they are both in the same game.

I am very critical of the snake oil guys who sell trading systems. These guys are selling data and suggesting various ways of filtering that data. Admittedly the latter steps into the area of selling a trading method somewhat.

But don't confuse them with the likes of Oliver Velez, Felton Trading and especially "Best Choice Systems" - now that's pure snake-oil.
 
I bought it a few weeks ago and and not sure how much use it is. I like the convenience of it's snapshot. Like other posts I wonder about how much revalence there is to this unusual market that isi all over the place.

The salesman sounds like it's the only thing you need for 60% returns yearly. I just don't see how the market for the previous 5 years can be backtested for an idea about the current market.
