Investing in Both Income and Growth Portfolios for over 50 years
Who I Am: I'm a retired individual investor. I retired at the end of 2013 after a 35 year career as a professor and research scientist at a major research university. So -- a career as a researcher and an educator, which is what I hope to continue here. Virtually every good teacher I've ever known says some version of "I learn more from teaching than my students do." There's a lot of truth in that, enough that there's an underlying selfish motivation for my writing here as I continue to learn about investing.
My professional life involved multiple international projects and collaborations, so I traveled extensively over those 35 years. I plan to continue doing so in my retirement. One consequence is that I'm liable to disappear from the site for extended periods. How can you miss me if I don't go away?
My investing priorities are building and refining portfolios designed to provide income and capital growth: Income for my retirement needs, and capital growth for my estate. My investing interests are tax-advantaged income from a range of sources, portfolio strategies, information- and bio-technology, and momentum-based strategic allocation.
Why I Write for Seeking Alpha: I learned long ago that "writing is nature's way of letting you know how sloppy your thinking is." The line comes from a Guindon comic strip of many years ago, and could not be more true in my case. When I did research professionally, I learned that writing it up forces me to think about details I might otherwise overlook. It's how I spent my working career, so it comes more or less naturally to me. I consider it an essential part of doing any research. So, the writing I do here is as much for myself as for the reader. As I started to contribute articles here, they grew out of research for my personal investment portfolios. They're based on things I've uncovered that are of interest to me and may be of interest to others of like mind. My primary purposes in writing them are to help clarify my thinking and to get feedback from others who may have very different opinions. It's those thoughtful comments that make Seeking Alpha such an important resource.
I try to actively engage myself in the comment streams in my articles, contributing what I can and learning from others. As a research scientist I spent a career spanning four decades devoted to free exchange of information vetted by rigorous peer review. It's a concept I firmly believe in. I hope to bring that approach to my interactions and contributions on Seeking Alpha and welcome critical commentary on anything I may contribute here. I especially encourage and appreciate thoughtful comments from those who disagree with me (although I will ignore obvious trolls and encourage others to do so as well). So, go ahead, start a conversation in the comment threads. It's one of the best things about Seeking Alpha.
My Investment Philosophies and Strategies: I maintain two portfolios. My income portfolio is a taxable account. I try to keep it separate from the growth portfolio which is housed in a series of IRAs, traditional and Roth. My income focus is on tax-advantaged income. In 2016 I face minimum required withdrawals from my tax-deferred accounts, so tax efficiency is an important consideration. The IRAs I see as my estate and are focused on generational wealth building. That means the growth portfolios have a long-term horizon, well beyond what an investor of my age might be expected to maintain.
Who Is Left Banker? Ah yes, the name. When I first joined Seeking Alpha I had no intention of being anything but an occasional reader. I saw it as another research site. So, I just ported a name I've used on other sites. I spent some of the best times of my life living on the left bank of the Seine and am always thrilled to be back in La Belle Paris. Add that I also like it because I find several subtle word plays there; I'll leave it to you to decipher that comment.
Finally, I've chosen to remain anonymous, which I feel obligated to justify. First, I have no professional role in finance and nothing to sell, so there is no advantage to be gained by "making a name for myself' here. Second, I value my privacy and have kept my internet presence as low-key as my professional life allowed. I certainly want to avoid any possibility of some internet connection trying to track me down. Odds against that happening are, of course, outrageously long, but why take them on at all?
Disclosures: I have no ties to the financial or security industries in any form. My interests are strictly personal. The banker part of the nym has absolutely no relationship to the profession of the same name. Readers should be aware that I am an investing novice, some might say dilettante. I do not give advice; what I publish is much more in line with a research notebook. Anyone who finds anything of interest will necessarily want to do his or her complete research and due diligence. It would be foolish to rely on my conclusions without having done so.
I have been an individual investor for nearly 25 years. My professional background is in finance and investing owning a Bachelor's degree from Michigan State University. Currently, I focus on retirement and dividend income strategies primarily through the use of funds and ETFs.
