The Dow Jones Industrial Average has gone up 8 days in a row (using CLOSE $). What's unusual is that this is happening before the Dow has hit a new all-time high. These “up 8 consecutive days” events usually happen when the stock market is making new highs.
Here are the historical cases in which the Dow closed higher 8 days in a row, and what happened next to the stock market (Dow and S&P 500).
