Welcome to Fluther.
How elementary an article do you want? That is, how much do you already know about the financial instruments themselves?
Because one thing that few “scholarly articles” would tell you, I think, is “advantages and disadvantages of either of these vs. the other”. Advantages and disadvantages would be wholly dependent upon the individual investor. Those aspects would deal with the individual’s:
– risk tolerance (and as well, the “perception of risk” that the individual has);
– investment time horizon;
– current inflation outlook;
– starting net worth;
– employment situation
These could all be interlinked and very much age-dependent as well as temperament-dependent. For that reason an article that purports to be “scholarly” (and by that I mean “objective”) will have a hard time dealing with such subjective aspects of investing as an individual’s psyche.
So the starting question still remains: How much do you already know? (That is, “really know” and not just “think you know” or “heard from some people” know.)
