Perhaps look at it like this, in the context of another investment class - imagine that you paid a sub to a local agent to recommend possible properties for buy to let investment. Once you received this tip sheet, you might look through it, circle a couple that look promising and go and take a look at them, think about how much any refurb might cost, any potential issues (damp, structural) what rental level they might yield, what the cost of the mortgage and any other expenditure might be and so on.
What you wouldn't (hopefully) do on receiving the tip is ring up the owner and offer them the asking price, no questions asked.
Tipsheets for shares are similar - some tips will be good , some will be bad. Tipsheets are useful for highlighting potential investments in the mass of those available, but not to be treated as 100% failsafe guides as to where to put your pension.
