What is the ruling on recommending stocks, and what is the ruling on receiving financial compensation for it?

There is no objection to colleagues recommending the purchase of a stock or commodity, provided it is permissible (halal). However, if the recommender merely points out the sale without any effort, they are not entitled to a wage, because work that involves no effort is not compensated. But if the recommendation involves effort, such as guiding to lost property, then the one who makes the recommendation is entitled to a wage.
