The Dow Jones Industrial Average typically shows weakness in the week following a 1,000-point decline, but historically posts gains in the subsequent one-month and three-month periods. CNBC analysis of nine such drops over the past five years indicates a median loss of 1.14% one week later, followed by median gains of nearly 2% after one month and 9.1% after three months. The most recent 1,000-point drop occurred on Wednesday, driven by the Federal Reserve's decision to keep interest rates steady and U.S. oil prices nearing $85 per barrel.
