let's discuss with david rosenberg frrose rosenbe rosenberg.of the economic data has come in soft. inflation last week. retail sales. new york manufacturing yesterday. can you square that with this record high stock market? >> well, you know, the record high stock market has its own particular dichotomy. in the past three months, what's kept the glue together has been basically six high-priced and high-market cap growth companies. outside of that, the rest of the market has moved sideways. you know, there's a bit of a bifurcation between the flashy growth companies and the rest of the market which has been flattish. >> what sort of signals are you getting from data? do you expect the rebound that everybody is looking for in q2? industrial production later today. what will you be watching to confirm it's there? >> right. i think the bar has been set pretty low. if we're talking about an improvement in the second quarter, we have to do better than 0.7% from what we saw in the first quarter. if the consensus say is 3%, 4%, which is where i see it,

david rosenberg shows us the results.ore treatment, after treatment. what is that telling you? >> he was completely shut down. when we talked with him here, he was exuberant. a different child. >> reporter: in california, brooke and her family work together on a sign of renewal, a fresh coat of paint. >> i'm wanting to start over and make my room more positive. i think if i can take my story and make other people think about things before they do it and help them to make a better life. i think that's really important to me. >> reporter: and then it's time for brooke to return to rehab. she's done well on this trial visit, but there's more to treating those underlying issues than simply taking her phone away. >> yeah, this is the worst day of the whole trip. every time. sad that she's leaving, but super happy that, you know, she'll be back soon. >> reporter: it may be a sign of her recovery that saying good-bye to her mom is harder than ever. do you feel like you have your daughter back? >> no. i have the new and improved

david rosenberg. his theory, yet to be proven, is that excessive gaming may change brain activity. >> you press the response pad for the letter "m." >> reporter: dr. rosenberg highlighted areas in red he says represent brain activity involving memory, attention, and decision-making. josh's brain scans are troubling. >> this is the brain processing center of the brain. there should be much more activity. >> there should be more red? >> more red. >> you looked at this and thought, this is a kid in trouble? >> this is a kid in trouble. >> reporter: his parents decide to take a drastic step. >> it's kind of stupid. i just play video games and i have to go to rehab for it? >> reporter: they send him into the utah wilderness and a program called "unplugged" at outback therapeutic expeditions. he and a group of boys will camp for weeks in this rugged terrain. there is no running water, no electricity, no screens. the only thing that glows in the dark, a campfire and the moon. josh isn't the only one in need

let's talk about central bank policy a little more with david rosenberg, chief economist and strategist and joins us from toronto. david, great to see you, first of all, happy memorial day. i wonder what do you think about the similarities between the e.c.b. situation and the fed situation because a lot of market participants would like to see the e.c.b. get a little more hawkish and seems inflation isn't giving them any reason to do so. is the fed in the same boat? >> i don't think the fed is in the same boat because we don't have a situation in the u.s. where we have the central bank actions holding yields negative out to the mid part of the curve. don't forget the fed has already raised rates three times and is pledged to do more. the u.s. economy is in a more advanced stage in its cycle than europe is and the monetary tightening cycle is in a more advanced stage as well. so i think the comparisons really start and stop there. i think that you're almost in a situation where europe is where the u.s. was three or four years ago when we had the taper tantrum. there's no tantrum in europ

for more we're joined by david rosenberg chief strategist and economist.k to "squawk on the street" and mike santoli, senior markets commentator. does snap do anything, mike, to ruin the narrative about technology in the amazing outperformance of the nasdaq, 18% since the election? >> i think it disturbs the big five of the nasdaq. really what's powering it ahead. i think coming into this week earnings did pretty much all they could do to reassure investors that basically the profit rebound is intact. so anything you got this week was more likely to detract from that view. so disney a little bit ragged and all the rest. i don't think it's a big mover right there, but along with macy's where the consumer side had bounced really hard, a lot of the stocks had a good few days. now you have another reminder that things are tough there. so not saying snap is helping things today, but i don't think that's the big swing. >> david, we're looking at all s&p groups now lower today. this is a broad based sell-off. haven't seen that in a while. yesterday, we were tryin
