Thank you all for your replies. It appears the nice return on commercial paper is in correlation to the risk. I'd like one clarification: The 30, 60, 90 day notes on commerical paper - are they paying a full 15% or more in interest for the term of the note? Doesn't sound as bad as taking a risk over a 6 months or a year, although the return might be higher for a longer note period.
I did buy several hundred shares of Tricom about 18 months ago, that has lost half it's value. As mentioned previously, it is the only DR company listed on the NYSE and is considered a well ran company, although it's debt level is half a billion.
