No One Ever Made a Dime by Panicking
With the financial markets in ruin, a lot of people today seem to be asking the same question -should I take my money out of the market? My answer - not unless you have some proprietary information as to why the market is currently overvalued (which you probably don’t). For the vast majority of people I would recommend staying in the market, but being defensive with your investments. If you pull your money out of the market, you are going to miss on the potential rally. In addition to that, the stock market has historically been a great place to combat inflation (when compares to the fixed income market). So my advice is simple - don’t pull out, diversify into uncorrelated assets.
It’s all about correlation
Diversification is not about slapping together a bunch of random stock and assets classes into a portfolio, it’s about constructing a portfolio of assets with little or, better yet, negative correlation to each other. In fact, if you are able to construct a portfolio of perfectly negative correlated assets you can technically construct a risk free portfolio with guaranteed returns. In practice however this does not work because it is very difficult to predict correlations in the future.
So how do you know what assets are correlated and which ones are not? Lucky for you there are number of site that provide such information- my favorite is www.assetcorrelation.com.
For example, the correlation matrix for US stocks over the last 182 days is:

So by way of the above graph if you are heavily invested in Energy sector, then you are going to want to diversify into the Healthcare sector because of the negative correlation there between those two sectors. For passive investors who don’t want to see their gains eaten up by unnecessary fees I recommend ETF’s, which have a favorable tax structure, low expense ratio and trade like stocks.
If you want to get even more defensive with your money, which I think you should, I would recommend you diversify outside of just the US stock market into all the major asset classes.

So by way of the above graph, if you only have investments in US stocks, you would want to diversify into some TIPS, US bonds or commodities.
In short, don’t pull out - uncorrelate.

Excellent post. In the past few days everyone has been calling me asking whether they should sell. As you point out, investing in uncorrelated assets is the key.
