Are we being played on our on Stock Market? has irrational Exuberance returned?

It appears irrational Exuberance has once again retrurned to the market are foreign investors bidding up stocks and then sell all their positions to get short term gains all the while knowing that it is a lot of America's 401k's buying these investment? What happens if they stop and has irrational Exuberance returned?

What is your source for this assertion?? Also the international markets have been going down in sympathy with the u.s. markets, so if this is their strategy, seems like they would be shooting themselves in the foot with this.

The u.s. markets are not controlled by foreigners. They are controlled by the large mutual fund companies - Fidelity, Vanguard, American funds, TRowe Price, etc. They have no interest in seeing the markets go down.

One other reason foreigners might be dumping their us stocks, is the decline of the dollar. When the dollar declines against their currency, it just makes sense to get out of us equities & invest in their own stock market.

On a personal note, since I'm DCAing into my 401k, I don't mind a pullback. I like buying my mutual funds at a 10, 15, 20% bargain.

There is no irrational exuberance right now. That pertains to people bidding up stocks to ridiculous levels based on speculation. Not only is the stock market not overvalued as a whole, it has been going down almost daily in recent weeks.
