Play

In finance and business slang, a play is a specific trade, investment or strategy aimed at profiting from a particular idea, theme or event. People talk about a technology play, a takeover play or an oil play. In the energy industry, a play also means a geographic area where oil or gas is thought to be recoverable.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

When an investor says that a stock is a play on lithium, they mean the stock is a way to gain exposure to the lithium market. The word suggests a deliberate move based on a view of what will happen.

It is informal, and a play may be a share, a fund, an option or a whole portfolio. There are many kinds of play.

A growth play is a company expected to grow fast, a value play is a company that looks cheap, and a defensive play is a business expected to hold up in bad times. A takeover play is a share bought in the hope that another company will bid for it.

Plays are often described as pure or indirect. A pure play is a company whose business is almost entirely in one theme, so it gives direct exposure.

An indirect play is a company that benefits from the theme in a smaller way, for example a supplier to the industry. In oil and gas, the word has a technical meaning.

A play is a region or geological formation where a particular type of reservoir is thought to hold recoverable hydrocarbons. Companies speak of shale plays and offshore plays, and they decide where to drill by comparing the costs and potential of each.

The term is useful because it makes the logic of an investment clear. It forces the speaker to state the idea: what do they expect to happen, and why does this asset benefit?

A play without a clear thesis is simply a guess. Non-specialists should treat the word with care.

A play is a bet on a view, and views can be wrong, so the amount invested should match the risk. It is wise to ask what the main risks are, what would prove the idea wrong and when the position would be sold.

In practice

Real-world examples.

1

Example

An investor believes that demand for electric vehicles will rise and buys shares in a battery maker. She calls it a play on the electric vehicle market and writes down why she expects it to work. She sets a limit of 5% of her portfolio for this idea, so a wrong view will not cause serious damage.

2

Example

A hedge fund hears market talk that a large pharmaceutical group may buy a small drug developer. It buys shares as a takeover play before any official announcement, using only public information. If no bid arrives, it plans to sell at a small loss and move on.

3

Example

An oil company has bought drilling rights over a shale formation and describes the area as its main growth play. Its finance team prepares a budget for wells, pipes and equipment over several years. The board reviews costs against output each quarter and can stop spending if results disappoint.

Case study

Seen in the real world.

Halcyon Energy is a fictional oil and gas company, and this story is illustrative. It had acquired rights to a new shale area and told investors that it was the company's biggest play for the next five years, supported by a written plan and a detailed budget.

The finance team planned to drill 40 wells at $8,000,000 each, a total of 40 x $8,000,000 = $320,000,000. They estimated that each well would produce enough to earn $12,000,000 of revenue over its life, which would be 40 x $12,000,000 = $480,000,000 in total.

The board approved the first 10 wells as a test and agreed to drill more only if early results matched the forecast. Results came in slightly below plan, so the company slowed down and renegotiated costs with its drilling contractors. Investors welcomed the discipline, and the share price held steady. The illustrative lesson is that a play is a thesis to be tested step by step, not a guaranteed return.

Watch out

Common mistakes.

  • Calling something a play without stating the idea behind it, the risks and the point at which the position would be sold.
  • Believing that a pure play is always better, when concentration increases risk and a single piece of bad news can hurt badly.
  • Betting too much on one play, so that a wrong view causes serious losses to the whole portfolio.

Questions

People also ask.

What is a pure play?

It is a company that focuses almost entirely on one industry or theme, giving direct exposure to it, but also leaving the investor with less protection if that theme falls out of favour.

What does play mean in oil and gas?

It means a geographic area or formation where oil or gas is believed to be recoverable.

Is a play the same as a trade?

Not exactly, since a trade is a single transaction, while a play is the idea behind one or more transactions and often the story that explains why they were made.
