Dear Subscribers,

The market rout continues—worsens, even. And the tech sector is taking its punches.  

So the questions on my mind this week were how bad is it, how long are we going to be here and what signposts should we follow?

I picked the brain of Goldman Sachs President Gary Cohn on these topics Tuesday, a day before Fed head Janet Yellen exacerbated fears and sunk stocks further.

Mr. Cohn, a former metals trader who has been the frontman at Goldman while CEO Lloyd Blankfein has been undergoing treatment for a curable lymphoma, discussed two possible paths for the tech IPO market, misconceptions about China, tech valuations and more.
