INVESTMENT BEHAVIOUR · 6 MIN READ

When rising prices make waiting feel like falling behind.

A market rally can create urgency. It cannot determine whether an investment belongs in your portfolio.

Howard Marks with the words Others are making money. I still need a reason to invest.

Rising prices create a deceptively simple question: does the investment still make sense at today's price?

That question becomes harder when markets are strong.

You see the gains. You hear the confident explanations. Waiting starts to feel like falling behind.

The excitement arrives immediately. The consequences of higher financing costs, changing required returns and pressure on household or business spending can take much longer to appear.

That difference matters.

The headline return is only the beginning

A convincing growth story still needs a reasonable purchase price. A promising investment still needs to survive expensive financing. An attractive expected return still needs to compensate me for what could go wrong.

Even a government bond offering an appealing yield requires care. A long-term bond can lose market value if yields rise further. Its suitability depends on when I may need the money and how much price movement I can accept before maturity.

No headline can answer those questions for me.

The uncomfortable part of waiting

I may decide to wait and still watch someone else make money.

My decision system needs to make room for that feeling. Otherwise, every rally becomes a reason to abandon it.

The purpose of a decision system is not to remove discomfort. It is to keep discomfort from quietly changing the rules.

Return to the calculation.

  1. 01

    What return should I require for the risk I am taking?

  2. 02

    Which assumptions must remain true for this investment to work?

  3. 03

    How would this decision affect my portfolio concentration and liquidity?

  4. 04

    What evidence would make me wait, reduce the position or walk away?

Rising prices can tell me what the market is doing.

They cannot tell me whether the investment fits my objectives, compensates me for the risk or deserves a place in my portfolio.

Someone else’s gains cannot tell me whether an investment belongs in my portfolio.
