Ways to Limit Opportunity Cost - Most Important is holding Part of your Portfolio in Cash

The most important determinant of whether investors will incur opportunity cost is whether or not part of their portfolios is held in cash.  

• Maintaining moderate cash balances or owning securities that periodically throw off appreciable cash is likely to reduce the number of foregone opportunities. 

Investors can manage portfolio cash flow (defined as the cash flowing into a portfolio minus outflows) by giving preference to some kinds of investments over others.  Portfolio cash flow is greater for securities of shorter duration (weighted average life) than those of longer duration.  Portfolio cash flow is also enhanced by investments with catalysts for the partial or complete realization of underlying value.

• Equity investments in ongoing businesses typically throw off only minimal cash through payment of dividends.  
• The securities of companies in bankruptcy and liquidation, by contrast, can return considerable liquidity to a portfolio within a few years of purchase.  
• Risk-arbitrage investments typically have very short lives, usually turning back into cash, liquid securities, or both in a matter of weeks or months.

An added attraction of investing in risk-arbitrage situations, bankruptcies, and liquidations is that not only is one's initial investment returned to cash, one's profits are as well.

Another way to limit opportunity cost is through hedging. 

• A hedge is an investment that is expected to move in a direction opposite that of another holding so as to cushion any price decline. 
• If the hedge becomes valuable, it can be sold, providing funds to take advantage of newly created opportunities .

If you are buying sound value at a discount, do short-term price fluctuations matter?

In the long run, they do not matter much; value will ultimately be reflected in the price of a security.  

• Indeed, ironically, the long-term investment implication of price fluctuations is in the opposite direction from the near-term market impact.  
• For example, short-term price declines actually enhance the returns of long-term investors.  

There are, however several eventualities in which near-term price fluctuations do matter to investors. 

1.  Security holders who need to sell in a hurry are at the mercy of market prices.  The trick of successful investors is to sell when they want to, not when they have to.  Investors who may need to sell should not own marketable securities other than U.S. Treasury bills.

2.  Near-term security prices also matter to investors in a troubled company.  If a business must raise additional capital in the near term to survive, investors in its securities may have their fate determined, at least in part, by the prevailing market price of the company's stock and bonds.

3.  The third reason long-term-oriented investors are interested in short-term price fluctuations is that Mr. Market can create very attractive opportunities to buy and sell.

• If you hold cash, you are able to take advantage of such opportunities.  If you are fully invested when the market declines, your portfolio will likely drop in value, depriving you of the benefits arising from the opportunity to buy in at lower levels.  This creates an opportunity cost, the necessity to forego future opportunities that arise.  
• If what you hold is illiquid or unmarketable, the opportunity cost increases further; the illiquidity precludes your switching to better bargains.
