In developed countries with stable currencies, knowing the percentage increase in an investment’s value is often “good enough” when deciding to invest or not. This pure look at a price increase or decrease is referred to as the “nominal” value of the investment. When you hear commentators on financial television talking about returns of the S&P 500 or other investments, they are referring to nominal returns.

However, if a country goes through an uncertain economic time it’s currency may experience inflation. Practically speaking, inflation is the loss in purchasing power of an individual unit of the currency. For example, in the US annual inflation is typically low, around 2%. This means that $1 in the beginning of the year will effectively have $0.98 buying power even though it still say $1.

Applying inflation to investing, we can factor in inflation to find the true returns on our investments, this is called “Real Return”. The real return is the effective increase of decrease of our investment after accounting for the change in purchasing power.

The S&P 500 10 year average inflation adjusted return is 10.42%.

LargestCompanies – Points of Understanding

In recent years the S&P 500 has been increasingly weighted towards a few very large tech companies. In fact, the 5 largest companies today account for nearly 20% of the value of the index. What this means for investors who use the S&P 500 in their investing strategy is that they too are being slanted towards these tech companies.

As these companies gain more and more prominence in the index, the level of balanced diversification of the index diminishes. Investors who are already heavily weighted towards tech and are using an S&P 500 index fund to add diversification should be aware of the diminished diversification they may be receiving.

For those who say investors shouldn’t try to beat the S&P 500 because it’s very unlikely. A case can be made against them simply by looking at the 5 largest companies in the S&P 500. The point here is that investors can benefit by adding exceptional companies to their portfolio which may allow them to outperform the market.

Understanding the S&P 500 index

The Standard & Poor’s 500 index (S&P 500) is a market-cap weighted index of the 500 largest publicly-traded companies in the United States. This means that all companies in the index are both companies in the United States and publicly traded.

The market-cap part represents the value of the company to equity investors (common stock owners). To calculate market-cap, the total number of outstanding shares of a company are multiplied by the current share price. Since the S&P 500 is market-cap weighted, they will use these values to figure out the influence each company should have on the value of the index. To calculate the weighting of each company, the company’s market cap is divided by the total market cap of all 500 companies.

For example, if Apple has a market cap of $2 trillion and the total market cap of all the companies in the S&P 500 is $30 trillion ($2 trillion / $30 trillion). Apple would have an approximate 6.67% weighting on the index. This means Apple stock price will influence the index by approximately 6.67%.

It should be made clear that the S&P 500 is not a mutual fund or ETF but simply a mathematical representation.
