the visitor perspective, 27 times this year so far we had the s&p 500 move 1% or more. 31 times we have seen that for the nasdaq. keep in mind last year for the entire year, that only happened eight times for the s&p 500. it is a lot of the same story here. we're seeing a lot of the meta-cap, large tech names mov lowere as people are making a reevaluation of what is going on out there in the market. trade concerns weighing on the market as well as concerned with the fed and the pace of rate hikes. if you want to look to where some of the biggest action was, if you look at the nasdaq biotech index the philadelphia semiconductor index. .we thought index violence in chipmakers because of a lot of competition coming out of china. , for the biotech index, this week we had insight

defend american technology, which is crucial to american economic growth. emily: david, obviously these mixed messages are having an impact on the market. there is still a lot of uncertainty great the president talking top and other people in the administration indicating more diplomatic solutions here. what is your take? david: maybe a missed something, but i'm not sure why kudlow says all they're doing is trying to save american technology. the wrong kinds of new rules on other products. i will say, as a journalisttec -- as a technology journalist, is one area where i understand trump's motivations because over decades, china has taken an attitude toward ip or they can take whatever they wanted and they did it in many cases. in ways that we would say are illegal and unethical. certainly, they do things like

google's corporate email or the gsa employee database. i think we have sort of sat around and let china do things to us as a country that one has to ask was that right. i still have huge admiration for china as a country and tech power, as an economy. they have done miraculous things. we should be happy they have developed their economy as well as they have. i think they have been changing. jump is responding to several little bit in the past, but i do understand why the white house would feel china has not played by the rules and wanted to give them a message they have to start. emily: in the meantime, we have been watching facebook and the market reaction given the cambridge analytica, etc. data controversy. facebook shares ending the day down. we spoke to sheryl sandberg theerday just before market close. she indicated a few advertisers

across the entire country that if you're going to be invested in equity markets, would like to be more defensive here. not just because of volatility in february. it is because we are in the later stages. emily: what does that mean? heather: it is a great question because defensive used to mean high dividend stocks and you thinkbut when about that today, those sectors are highly sensitive to interest in thissing from and particular bout of volatility, it is coming with interest rates rising. albeit not today, but throughout this period. the best defense is a good offense in today's market. you want companies which are high-quality, running at lower leverage, and have good growth potential. a lot of that still is tech. emily: despite the last few weeks? heather: despite the last few

weeks. we're not ignoring the concerns over regulatory, those are real, but the reality to earn is still intact. emily: and the you can't speak to specific names, but when you look at facebook and amazon and companies like that -- are they going to weather the storm and is this just a blip? heather: where we are focused as of today and right now and tech markets is those enterprise technology companies, which could sell directly to corporations. as we look at what is going on in corporations today, it is distinct from what is going on with the consumer. corporations are looking for a windfall from the recent tax bill. as we analyze the attack from corporate conference calls -- the tech, across the u.s., you are at a huge amount of tech spending. it has been put off for years at

this point and it is now coming in. those companies, which are selling to other companies are see sales growth into this. potentiallymazon because of their businesses there? heather: absolutely, when you look at companies who are augmenting their tech. emily: what is happening in the private markets? yet exposure across the board, whether it is venture capitalists or startups -- i know blackrock has a holding in uber. talk to us about the activity there. they run with semipermanent capital below the radar and don't need to be doing what the herd is doing in terms of keeping up with peers. they can be very specific and continue to hold private investments and look for private investments.

i would say that has backed off from years past when you look at investments, and really get investments of the companies that aren't necessarily technology but are willing to utilize technology in their businesses. those are poised to advance. strongs still a very interest in private investments, partially because as you see in central banks, they create wealth to the extent they create money to put into public markets. those private markets have not been a recipient as great of an extent. we still see pockets of opportunity, and will are looking for things that are a little bit you do idiosyncratic. emily: there's potential regulation and tariffs, and these big companies can be facing.

how are you taking that into consideration? heather: it is very hard to predict the next move from a policy or relation standpoint. it has traditionally been very hard and it is the case today. if i were an investor -- you are concerned with the state of u.s. revelatory policy or trade policy -- perhaps look beyond the borders of our own country. the techink about it, sector is a global sector and u.s. tech companies are running 17 and change, it is not too far -- five-year average for the broader market. in emerging asian tax, it is 14 times forward earnings, which still is a very different than the broader market. yet they are living in interesting segments in the market. from a regulatory perspective and a are not seeing changes because they are under a different regulatory regime since the beginning.

first week, and you see the government fostering some dialogue that is concerning around h-1b. emily: given the rhetoric out of the administration. where do you think it is going? brynne: i will say with our customer base we are seeing a couple of different things. firstly, employees are nervous. people are nervous to move to the u.s. than they have ever been. it is challenging for companies in terms of recruiting, and that is happening day in and day out. leverageee companies short-term mobility to the u.s., some people coming for a month on different these attacks and people who travel frequently as they tried to figure out where the policy is going. a lot of issues at play, and many of these foreign workers are part of the backbone of silicon valley and the tech industry.

quickly, all of these visas are gone. it is connected to what mark cuban said earlier, we technologicalte a economy, and the policies we adopted a national level are not really appropriate for the nature of where we are. certainly the fact that we would have so many openings in tech related jobs as green mentioned combinednne mentioned, with the fact we don't have appropriate education training to create the new core of trained tech centric workers we need, it is like are shooting ourselves in the foot as a country. emily: i am interested in the diversity issues and the tech industry and some suggested to me perhaps the governor can out boy did -- avoided, most of the

visas are awarded to man. what you think the of the idea that the u.s. can roll them out equally and combat gender diversity issues in silicon valley. hugee: we know there is a gender imbalance and there is a pipeline issue. i would talk about it more broadly, across the world there are less women were as mobile as men. there is some unconscious bias that goes into selecting women to take a work opportunity at a different location. a womanloys assume that is not going to take that career and is not going to want to move because of family reasons. i encourage companies to be the starter of that and encourage female employees to take mobility opportunities. we know there is a direct link with mobility and leadership, and it is a way to make your

leadership pipeline much more diverse by moving more women into mobility opportunities. emily: i was the is impossible to predict the implications here, but will we are seeing impacting the town flow in silicon valley over the longer term? brynne: i think it is going to affect it. people feel a different tone in the u.s. and are looking at other markets. i lived in london for seven years and we saw similar dynamics in the. u.k. u.k., we sawn the the pipeline of applications from outside of the u.k. plummet dramatically overnight with brexit. i have a concern that there will be a similar effect happening in the valley people -- of people wanting to come, and that could be crippling for the technology industry. kennedy, thank you

the social media giant also announced a new plan the battle fake advertisements. facebook will no longer require more disclosures for advertisers want to push a political viewpoint. this means verifying your location if you are buying -- facebook will now require disclosures, i should say. kirkpatrick david -- david, i have been dying to talk to you about what is going on with facebook. david: that's do it on the air. emily: the news keeps piling up. i cannot believe the story i read about facebook executives able to unsend messages. it seems to be one thing after the other, adding up to more reason why we shouldn't trust this company. david: it goes contrary to the way mark's talk about this company this week that he should have deleted his side. he did that in a string that

involved me, by the way. i think unfortunately, they still don't really have a clear message of how they are responding to this set of crises. and it it is pretty sad is not getting them out of trouble at the rate they would like. i am afraid it is not going to get them out of trouble at any speed at all. the trouble is likely to be long-term, and there is a number of very disturbing signs in my opinion. this is a big problem that is unresolved. emily: let's talk about how they are responding to it. they admitted they are slow but not executives are out there. mark zuckerberg did in our blog call with reporters where he took unfiltered questions. i sent them with sheryl sandberg yesterday, and i asked how personally responsible you feel?

she said she feels deeply responsible and i am sorry. we make mistakes. take a listen to what she didn't do enough of. we also didn't build our operations fast enough, and that is on me. onhad 10,000 people working security at the beginning of the year, and that the end of the year will double to 20,000. we're massively investing in smart technology. and we are doing all of this to make sure that we get to a place where we can proactively protect people's data. emily: david, what do you make of what sandberg is saying? interesting and great they want to proactively protect people's data now. it is great that mark zuckerberg said it was a huge mistake that he had done it earlier. the key question is, why didn't they do it earlier?

i have to say one reason is, the profits have been flowing in so gushingly for so long, that they got confused about why they were at this whole game. i think they said two things this week that i was distressed by. when mark said, basically and that very good press conference -- it is good and he had that. i do think he has ever been a press conference. emily: i think that was a first. david: it is great that he did that in response to crisis, too bad he didn't do it before. one thing he said is our business -- he was impressed by a reporter. he said, our business is connecting the world and building global community, and the ads are a way to pay for it. and cheryl and her interview with you yesterday made a major faux pas when she said we never optimize for profitability.

as a shareholder i would have been appalled. i don't think any business executive should ever say that. it should not be the case. the fact she is saying that mark is saying the thing about me a connection being more important than at targeting business -- it says to me that they aren't being honest with themselves about why this all happened. it happened because they were focusing too much on the profit and not enough on the security. it is as simple as that. it is self evident to all outside observers. they can't seem to confront it, and that is a painful reality to them and they have to confront it. emily: where does the buck stop here? i tweeted the sandberg interview and i got a ton of replies from angry users. mark zuckerberg is going to speak before congress, that it

doesn't appear leadership is going to change. cheryl still believes in mark's leadership. what is next? what can the company do to repair its reputation, or is this going to blow over and people are going to forget? david: i don't think it will blow over, i think this is a long-term readjustment that is going to take years, and probably never and. the thing that worries me from a macro point of view is the company faces challenges two sides. the statement zuckerberg made about the checking of political and policy adds. he talked and a note of hiring thousands of new people to implement that. the costs are going up in order to do a lot of the wonderful things they said they are going to do. i would to make clear they said they are going to do a lot of great things, and i am that they are doing that. on the other hand, one thing we don't know is the impact and what it is going to be on the at

targeting business of the large number of changes they made to the way personal data is managed and flows inside the system. analysisotten any real of what all those changes are going to mean for the ability for advertisers to get the exact targeting that has been the primary reason they advertise on facebook. mediumhe most targetable in the history of media for advertising. emily: david kirkpatrick, we can go on and on. thank you as always and we appreciate your thoughts. in washington dc covering mark zuckerberg's testimony next week, and i will speak with the newly minted ceo of sci-fi on monday. this is bloomberg. ♪
