Anchoring Bias

As investors, unfortunately, we do not dictate the price at which we purchase an investment from the marketplace. As we know, the opposite is true: the market determines the price. We can wish all day for the market to let us purchase shares of Amazon stock at $10/share, but no matter how much we want it, buying at that price may not be an option that is available today. It has been a long time since Amazon traded close to $10/share, and it is currently trading at over 20 times that level. Does this mean that investing in Amazon at its current price is not a good idea, and you should wait until it drops back down to $10 before considering an investment? Probably not; Amazon may never drop down to that price. If Amazon stock fits into your overall allocation and long-term plan, then purchasing at today’s price can still make sense.

The same logic applies to investing in fixed income. You might have memories of the 10-year Treasury yielding over 8% back in 1995 or perhaps over 10% in 1985. Or a 4.75% yield from the start of 2025 is what comes to mind as an appropriate yield. Yet, remembering that these yields were once available does not mean that you should wait until yields return to these levels before investing in fixed income. Could 10-year Treasury yields move back to these levels at some point in the future? Sure, but it is also possible that we don’t see those yields again for a very long time, if ever. Regardless of what you consider “normal” yield levels, there is no certainty as to when or if those yields will return.

Viewing current price or yield levels and making a judgment of value based on what we considered a “normal” level in the past is referred to in psychology as an anchoring bias, meaning that our minds are “anchored” to the past value and use it as a benchmark to determine value. Every investor will have a different “anchor” for interest rates. This is commonly tied to some point in the past that our minds are anchored to but could also be linked to what “experts” claim is a normal level for interest rates.

10 year treasury

While yields have fallen somewhat over the past few months, across most of the fixed income market they are still at more attractive levels than we have experienced for most of the past 15+ years. To provide some context, the 10-year Treasury yield is currently over 150 basis points higher than its average over the past 15 years (4.13% versus an average of 2.55%). The municipal market tells a similar story as the 30-year AAA municipal yield is over 100 basis points higher than its average over that timeframe (4.17% versus an average of 3.05%). While we may not be at the recent peak of interest rates, yields are still at very attractive levels from a historical perspective.
