Many people follow the market indexes, but how much do you really know about them?
To help cut through the noise, here are a few facts that may surprise you and offer a better perspective on what the headlines mean.
đ The Dow still uses a price-weighted formula from 1896. A stock with a higher price, not a larger company, can move the index more.
đ The S&P 500 tracks 503 stocks, not 500. Itâs market-cap weighted, so the largest companies drive performance. The index has changed a lot over time. Only five stocks have been on the index since the beginning.
đ The Nasdaq Composite includes 3,300+ companies, not just tech. However, with a large tech exposure, it can move more quickly than the others, especially in volatile markets.
đş Point drops can mislead. A 500-point drop in the Dow meant -5% when the index was at 10,000. Today, with the Dow around 40,000, itâs just over 1%. Percentage matters more than points.
Bottom line: Indexes are useful toolsâbut theyâre not strategies.
Context matters. So does staying focused on long-term goals.
