The document discusses how 100 point moves in the Dow Jones Industrial Average, though they may sound large, have become more normal and should be expected given the overall rise in the Dow over time. It provides examples of how a 5% and 10% decline in the stock market would equate to drops of around 850 and 1,700 points respectively. The document advises investors facing market declines to maintain a long-term perspective and not panic sell quality investments, as declines provide opportunities to buy stocks at lower prices.
