Goldman Sachs's chief equity strategist, David Kostin spoke Tuesday with CNBC

  • "There's a little bit of asymmetry in terms of the downside risk toward a level in the S&P 500 of around 2,000, which is down almost 25%, and upside of around 10% to a target at the end of the year of 3,000"

Unpicking/deciphering that - he thinks lower is more likely.

More:

  • important investors not get too keen to buy
  • during the 2008 financial crisis the market took several months of violent moves up and down before ultimately putting in a lasting bottoming on March 9, 2009
  • "I would just remind you that in 2008 in the fourth quarter there were many different rallies...but the market did not bottom until March of 2009"

CNBC interview is gated but MarketWatch had some excerpts from it.
