he distinction between a “proprietary” option and a “shared” option is fundamental in strategic investment analysis, as it determines the value of the opportunity and the optimal exercise strategy (the time to invest).

Here are the detailed differences

1. The Owner Option (Exclusivity)

An option is said to be “proprietary” when the company is the only  one that has the ability to act or invest in a given opportunity.

• Source of exclusivity: This exclusive right often comes from barriers to entry or specific assets such as a patent, a strong brand, a unique technological competency, or a prime geographic location.
• Strategic involvement: The company has a temporary monopoly on decision-making. It can choose the optimal time to exercise the option (e.g. wait until the market is ripe) without fear that a competitor will take its place.
• Example: In the pharmaceutical industry, the filing of a patent following an R&D phase confers a proprietary option. The company has the exclusive right to launch the drug, preventing imitation by competitors.

2. The Shared Option (Competition)

An option is said to be “shared” when the investment opportunity is accessible to several economic players, including competitors.

• Nature of opportunity: These are typically innovations that are accessible in the public domain or open markets with no significant barriers to entry. The company has the “possibility to…” But so do his competitors.
• Strategic Involvement (Value Erosion): If the company exercises the option (e.g. launch a product or lower prices through unprotected innovation), the industry will respond. Competitors will imitate the initiative, which will quickly lead to the temporary loss of the competitive advantage.
• Link with Game Theory: The analysis of a shared option requires taking into account the rational strategic interaction between the actors (Game Theory). For example, if a company invests to reduce costs (shared option) and lowers prices to gain market share, competitors will likely respond by lowering their prices as well. In the end, the entire industry will have invested for lower margins, with the profit being passed on to the customer.

Summary: The impact on the decision

The qualification of the option (proprietary or shared) is an essential component of the analysis:

• Value: A proprietary option usually has a higher value because it protects future flows from competition (“upside” protected).
• Exercise decision: For a shared option, the threat of a competitor’s pre-emptive entry may force the company to invest earlier than it would like (“kill the waiting option”) so as not to lose the market, while a proprietary option offers the luxury of time.
