The Nasdaq finished at its highest level since September 2000. The Dow is less than 3% below its all-time high from early August, while the S&P 500 is less than 2% shy from its all-time peak.
The broader market was likely moving higher again as concerns about a U.S.-led military strike on Syria have been pushed to the back burner. A military strike had seemed imminent last month and caused some extreme market volatility recently.
But politicians in Washington continue to debate the pros and cons of a strike. In addition, Secretary of State John Kerry raised the possibility Monday of avoiding an attack if Syria were to give up its chemical weapons.
Investors were also encouraged by more evidence that the Chinese economy has stabilized. Industrial output rose a robust 10.4% in August, the strongest in over a year. Retail sales and fixed asset investments last month also rose more than expected.
The reduced geopolitical tension and healthy economic data also sparked gains in Asian and European markets.

The Dow's overhaul: Nike(NKE), Goldman Sachs(GS) and Visa(V) were also in focus, as the three will be the newest members of the Dow, replacing Alcoa(AA), Hewlett-Packard(HPQ) and Bank of America(BAC). Shares of Goldman, Nike and Visa all rose on the news. Alcoa and HP fell slightly while BofA was up more than 1%.
One trader joked that BofA may do even better now that it's out of the Dow. Another wondered if we'll still care about Alcoa's earnings. The company has typically been the first Dow component to report results, an honor it will soon lose.
Portfoolio: $BAC DOW stocks aren't supposed to double in a year. That's why they took it out, they know this is going to $30..
RyanDetrick: Imagine if someone all of a sudden starts reporting earnings before $AA. Might never hear from them again.
And some traders stressed that over the long-term, the changes may not have an impact.
