Check out this article by Dividend Mantra: http://www.dividendmantra.com/2013/08/why-i-hold-100-of-my-equity-investments.html
It’s titled “Why I Hold 100% Of My Investments In A Taxable Account.” This, my friends, is how you think through a decision. Jason explains what the conventional wisdom is with retirement asset allocation, and then goes on to explain why it makes sense for his own financial planning to deviate from that. That is exactly how you should approach problems in life—you figure out what the generally accepted “good” practice is for a given situation, and then you apply the facts of your own life to see if it fits. Jason’s Dividend Mantra blog is one of the best homages to good judgment and critical thinking that is out there today.
Pete at Mr. Money Mustache, who is soon going to get his own post dedication on this site, recently put out an article titled “The Black Hole Second Home.”
