It might be OT but Saul has posted about info gathered from Zacks.
Visa (V) Stock Sinks As Market Gains: What You Should Know Zacks Equity Research March 18, 2019
Visa (V) closed at $155.03 in the latest trading session, marking a -0.28% move from the prior day. This change lagged the S&P 500’s 0.37% gain on the day. Meanwhile, the Dow gained 0.25%, and the Nasdaq, a tech-heavy index, added 0.34%.
Not uncommon. Most of the services Fidelity uses to publish company ‘research’ updates are purely robotic. But that daily price move report is true pure waste.
I haven’t been too impressed with Zacks, either. The better stuff seems to be more cottage-industry people who don’t try to analyze every stock in cookie-cutter fashion, but get to know a much smaller collection of stocks very well.
There are some cookie-cutter criteria that work better than others, but Zack’s method is not one I’d be that swayed by on a stock without confirmation by other methods.
AAII, a non-profit, gives information and examples of a lot of methods, NOT including Zack’s:
I think you have to be a paying member to see stocks that pass the screens, but I think you can see the screening methods described for free.
I wonder how the performance of people here would change if you added a constraint or two, such as limiting the P/S ratio. Saul’s main criterion is probably revenue growth, while also noting change in profit/loss as revenue goes up. (So that, e.g., if revenue grows well, but losses grow in similar fashion, that makes the stock much less attractive.) There’s also a fair amount of what I might call holistic analysis, based on lots of experience, cutting to the chase in the company’s “story.”
