They're tricky, that's for sure. I doubt you'll find a website telling you how to play them. I never saw one. S-8 bounces are pretty reliable if there is no other dilution going on. You have to read the filings and also take into consideration if it's an S or an E filing, or a regdex, is it convertible debt? Forget it you can't calculate those debentures because they convert shares into infinity.
One thing I have learned, about SB-2's (the 424B3's you see on this board for the most part), is that they register more than is needed in case they can't pay back the debt, a lot of times twice as much. If the company happens to be doing well, then we do see a bounce after it's paid back, or even before, if they are paying cash. Like I have said, you have to combine the chart with the filings.
Also, Cornell stocks in my observations like to have runs up together, so keep an eye on those when they are running, but you should never hold long on them.
Do your own DD. My posts are my own opinion other than those that are SEC filings found on the EDGAR website.
Quit ripping my pages tyia it's cool to be original.
