In my example of what a diversified portfolio looks like, I used a 70% Stock portfolio as an illustration. To save you the time and math, I’ve started a series of posts that look at a range of diversified portfolios from 100% Stock to 0% Stock. I’ll break these portfolios down in 10% increments. Today we’ll look at an 80% Stock portfolio.

Here’s a pie chart depicting the asset allocation for a diversified 80% Stock portfolio:

I think it’s really important to emphasize those last two quick facts. If you have a time horizon of 30+ years, there is no historical period where you would have averaged less than an 8.0% annual return. (Even if you started just before the Great Depression!!!) And 85% of the time, you would have had a higher than average return over a 30 year time period. Take comfort in those facts when the media barrages you with doom and gloom news every day.
