How can interviewers verify whether the analysts/managers/execs. they are talking to are telling the truth as to what positions they may have in a stock they are talking about? I am sure they do not have the power to audit the firms involved. So when a fund manager says he is holding a staking in let's say cisco and talking about its prospects, how can we know he is not simultaneously selling or shorting it? I know it is cynical but to quote Pres. Reagan to the Soviets: "Trust but verify." Ciao.
The Bob Pisani's of the world really have no idea as to whether or not their "sources" or "guests" are being truthfull and credible. CNBC does NOT pay these people for their info as "sources" to their reports.
