This is not a post about why anyone should be running from the equity (or debt) markets. I’m firm a believer that most individuals should be as close to fully invested in the markets at all times. Market timing is awfully hard to accomplish. Nor do I believe that anyone needs more than 3 months in emergency fund assuming there are other sources to be tapped like equity lines of credit, maturing CDs, etc. Yet contrary to all those beliefs above, I believe many individuals would greatly benefit from having a cash stash.

There’s nothing else like cash. Not just cold hard cash in the form of bills and coins, but cash in a savings accounts, money market funds, checking accounts - basically what is defined as the M2 money supply less CDs. Unlike other investments which can be both illiquid and are generally invested with a time frame in mind, cash is definitionally liquid, and has no time constraints upon it.

However, the virtue of holding cash is not just having cash itself, but the opportunities that having cash begets. How many times have any of us said, “If I only had the money, I would’ve made fortune in X.’ X might be great real estate purchase. X could be an incredible stock idea. X could have been put into helping a friend start up a business. I don’t believe in get rich quick schemes, but I also believe that many successful individuals take calculated risk with the right business opportunities. In order to take those financial risk you either need to have the cash or borrow it. Unlike corporations, individuals cannot easily go out into the debt market and borrow money. The best option we have is to borrow via home equity. Personal loans generally have onerous terms that make them unpalatable for the purpose taking risks. Even if I did have good access to funds via a home equity line, I would not want to be 100% leveraged in a risk taking venture. I would be more comfortable putting cash to work and then using some leverage.

The question is how much cash is appropriate? Warren Buffet holds over 50 billion in cash at Berkshire Hathaway for potential investments. This is nearly 1/4 of the company’s market capitalization. 25 percent would be very large percentage of someones’ networth to be held in cash. I believe for most people the percentage held in cash should be much lower, and generally slides up as someones’ networth increases. Cash in some ways is the investment you make after you’ve made all your other investments. I can’t imagine most people would want to target more than 25% in cash holdings, but many people would be well served by being 10-20% cash. However, the most important part of being in cash is understanding that you are the type of person who wants and plans on taking risk with that cash.
