Still fairly new to the Corporate Bond purchasing efforts vs funds. I am curious about your thoughts in terms of placing too many dollars in one corporate bond holder. For example, I have purchased more Royal Bank of Canada bonds than others in my portfolio. I see more that I would like to purchase but am concerned about too much concentration. There are other bonds that present themselves as alternatives but still not the same. So, my question is do you develop your portfolio with the idea of limiting the concentration of funds in any single bond holder for a 5 year or so time frame? Or do you purchase the best opportunity assuming the rating and any other knowledge of the bond holder makes it safe enough and the best deal is pursued? I am sticking mostly with A rated bonds and typically do not buy the lowest end of the A ladder. Thanks
