Is there optimism on Wall Street right now? YES

From the New York Times

In 1999, technology companies with no earnings or sales were valued at billions of dollars. But this time was different, investors told themselves. The Internet could not be missed at any price.

They were wrong. In 2000 and 2001 technology stocks plunged, erasing trillions of dollars in wealth.

Now investors have again convinced themselves that this time is different, that the credit crisis will push economies worldwide into the deepest recession since the Depression. Fear runs even deeper today than greed did a decade ago.

But in their panic, investors are ignoring 60 years of history. Since the Depression, governments have become far more aggressive about intervening when credit markets seize up or economies struggle. And those interventions have generally succeeded. The recessions since World War II, while hardly easy, have been far less painful than the Depression.
