Recommending a stock to erstwhile contacts or associates, or friends, can be hazardous. If things pan out wrong you might end up with some serious guilt trips. (Or, worst case, a pair of cement boots.)
But I don't think it hurts to point out this or that stock that is "worth looking at", because of this or that lucrative development or result "that may or may not happen", and what will happen if it doesn't.
Explain why it's in your own portfolio, and advise "don't bet the farm!" Use the term "very speculative" often, especially in ref to biotechs. ANY biotech.
