The Long and Short of Portfolio Construction

Join Our Mailing List

Long-Short Portfolio Construction vs. Long-Only

[By Dr. David Edward Marcinko MBA CMP™]



Long-Short is an active portfolio construction discipline that balances long positions in high expected return securities and short positions in low expected return securities of approximately equal value and market sensitivity. This type of portfolio is “neutralized” or immunized against changes in value of the underlying market and, therefore, has zero systematic (beta) risk. If the selected securities perform as expected, the long-short positions will provide a positive return, whether the market rises or falls.


While long-short portfolios are often perceived and portrayed as much costlier and much riskier than long-only, it is inherently neither. Much of the incremental cost and risk is either largely dependent on the amount of leverage employed or controllable via optimization. Those costs and risks that are not controllable—financial intermediation costs of borrowing shares to short, the trading costs incurred to meet long-short balancing, margin requirements, uptick rules, and the risks of unlimited losses on short positions—do not invalidate the viability of long-short strategies.

Long-Short Advantages

Compared with long-only portfolios, long-short portfolios offer enhanced flexibility not only in the control of risk and pursuit of return, but also in asset allocation. Basic market-neutral portfolios achieve a return consisting of three components: (1) interest on funds held as a liquidity buffer, (2) interest on the short sale proceeds maintained with the broker, and (3) the return spread between the aggregate long and aggregate short positions in the portfolios.


Share borrow-ability and uptick rules make short-selling more difficult and costly than going long. Also, it may be legally or contractually restricted for some investors, such as mutual funds. Inefficiencies may be concentrated in overpriced stocks and, accordingly, short sales of the most overpriced stocks may offer higher positive returns than long purchases of underpriced stocks.


Long-only portfolios are confined to altering the weighting of securities within an index in order to realize an excess return. Long-short portfolios are not constrained by index weights and, because they can short securities, they can “underweight” a security by as much as investment insights and risk considerations dictate. Long-short portfolios can be enhanced by “equitizing” them using stock index futures.

Why We’re Publishing and Advertising at the ME-P

And, Where We Stand on Funding

By Ann Miller RN MHA



Join Our Mailing List 

Starting next month, the Medical Executive-Post will begin publishing advertising on its web site, and likely soon we’ll include it in our daily emails, special offerings and send-outs, etc.


We’re doing this for the usual reason: to help raise revenue that can fuel our operations, promoting what people in the corporate world call “sustainability.”

Philanthropically Driven

The ME-P, as you probably know, has been funded almost entirely by philanthropy. Much of that has come from our founding donors and the Institute of Medical Business Advisors, Inc. www.MedicalBusinessAdvisors.com 

More recently, some has come from people able to make small gifts. And, important support has also come from readers who have contributed what they can. In fact, you may support us right here.

We wish top remain stand-alone and independent. “Un-biased” and Un-bought” as we like to say around the water cooler.  Advertising will help us get there. But, if you’re interested in advertising directly, please let me know.
