Diversification Doesn't Matter Until It Does

&

As we sit near all time highs in the stock market, talking diversification and broadening out your portfolio can be hard to implement. Why sell the holdings that have treated you so well?  

However, as you can see by the chart below, provided by YCharts, from the end of 1999 through 2007, a $10,000 investment in the S&P 500 grew to just $11,409, including reinvested dividends.  Meanwhile, emerging markets reached $31,260, small-cap value climbed to $25,830, and mid-cap value rose to $25,120. Developed international stocks also finished ahead of the S&P 500.  Overconcentration in a particular index or sector could be detrimental to your portfolio, especially when factoring in distributions as well as the possibility of a poor sequence of returns.

Currently, we are in a period of concentration we have never seen before. According to The Compound, the top 5 S&P 500 stocks (NVDA, AAPL, GOOGL, MSFT, AMZN) are now equal in market cap to the bottom 434 stocks as Doug mentioned on the radio show last Sunday. This has worked out well for those of us who have been invested in these companies. Going forward, diversification may not be the most profitable thing to do, but t is the right thing to do. When you are at or near retirement, you give up performance for stability, and that is what diversification does. Combining diversified equities with appropriate bonds and cash reserves can help reduce pressure to sell stocks during difficult markets and gives you flexibility when distributing assets.
