So I'm getting back into the stock investing slowly after years of not trading, and given my schedule I feel my time would be best spent doing long term passive options like LEAPs and slowly dumping a percentage of excess capital into index funds for even more passive income.
I have options experience but it would be prudent to have a full refresher course, does anyone have any recommendations for videos to watch and good DD tools? For the latter I'm hearing of new ones like Predicting Alpha but those are paid subscriptions which I'm always wary of. Not asking for a guide for doing DD specifically but just vehicles in which to do it.
