Q: Would you nibble at Blackberry at today's price or best to stay away. What do you see in the future for this comany? Anything positive? Thank you.

Q: How should one employ the forward price to sales multiple to determine value? What I’m trying to figure out is when to avoid a stock that has gone over its skis as they say. Take stocks from ultra to pstg to Crwd - we go from 1 x earnings to 23 x. By that gauge, one presumably buy Ultra. But when I think of value, I remember how I once bought Rim over Apple because the former looked cheaper. Can you comment on any guideline for us of this metric? Thank you,

Jason

Q: BB is in a downtrend, but why 10% and 5% in the last 2 days? Anything on the proposed split? Thanks.
