S&P 500 Snapshot: Selloff Day Six

Today major equity indexes in Asia posted gains, but their Europe and US counterparts finished the session uniformly in the red. Yesterday's loss for our benchmark S&P 500 was its sixth consecutive decline ... something that hasn't happened since August of last year. The index hit its 0.25% intraday high shortly after the open and sold off to its -1.33% mid-afternoon low, at which point a "buy-the-dip" strategy halved the loss to -0.68% at the close. About that "buy-the-dip" strategy: It was no doubt triggered by the S&P 500 dropping below the 2100 level, a situation that lasted for about eight minutes.

The 10-year closed the session at 1.83%, down one BP from the previous close. Here is a snapshot of past five sessions in the S&P 500.
