Just for kicks, I took a look at the keyword stimulus on Bloomberg and compared it to the S&P 500 index.

There is an obvious link to the use of the word when markets are dropping. Correlations were surprisingly high between the two and appears that the use of the term in stories is overused as the markets trend lower.

Of course there is no absolute relationship between the two, but it is interesting that the media is continually priming the markets just when it looks like a cave-in is around the bend.
