As credit markets continue to normalize next year, corporate credit will be seen as one of the most attractive investments, Barclays Capital wrote in a note Friday.

Investors will favor corporate bonds because they will see few comparable alternatives with as much return potential, since economic growth is slow around the world, currency yields are low and there's a generous supply of long-dated treasuries.

You probably consider yourself to  be a savvy, level-headed, well-informed investor. You're a financial executive, for goodness sakes.

While you may very well be all that, a new study shows that your investing behavior has little to do with anything else but your DNA.  That is, if your portfolio has a cautious allocation and, say, you eschewed too many Internet stocks back in the late 90's, your prescience most probably arose from your genes, not that fancy MBA.
