The Two Primary Drivers of Investment Performance

Morgan Ranstrom |

There are two primary drivers of investment performance:

  1. The percentage of your investment portfolio that is allocated toward stocks 
  2. Investor Behavior

Why Stocks? 

The percentage of you portfolio that is invested in stocks matters because equity investors get paid to take on the higher risk, or uncertainty, of stock investing. We call this the equity premium and it basically means that historically stocks win from a performance perspective.

Why Investor Behavior? 

Investor behavior matters because investor performance has historically been waaaaaaayyyyyyyyy different than investment performance. For example, Dalbar, a Massachusetts research firm, calculates the difference between investor returns (the return the average individual investor in a mutual fund receives) and investment returns (the actual return of the underlying investment). Their research confirms the anecdotal evidence: we (i.e. humans) suck at investing. We panic, we get greedy, we buy high and sell low, and we fall victim to a whole host of other behavioral biases.

Here’s the amount, in percentage terms, the average investor trailed actual stock market returns annually, according to Dalbar (Source: NY Times):

  • 5.88%, annualized, over 30 years
  • 3.46%, annualized, over 10 years
  • 4.35%, annualized, over 5 years

Frankly, we just aren't wired to make consistently good investment decisions.
