As the Nasdaq sets new records, a reminder how highly valued tech stocks are today

Today the tech-heavy Nasdaq Composite closed at an all-time record high of 8,814.23, up 0.91% on the day.

The Nasdaq is up more than 32% on the year. Turning the clock back, the Nasdaq Composite is up around 60% from the end of 2016. Compared to the anti-records set in 2009 during the doldrums that followed the 2008 crisis, the Nasdaq is up a staggering 594%.

The huge run in value of technology stocks since the last recession is historic. And, given the length of the current global economic expansion, somewhat lost on regular folks.

Times are good, and it’s worth reminding ourselves of how good. After all, the private markets — the world of startups, venture capital and the next big companies — follow the public markets’ lead. If we understand what’s going on with tech stocks, we’ll better understand what is happening with your local startup cohort.

Or more precisely, if you’ve been confused about why every startup is worth a bajillion (plus or minus) dollars, this is why.

A record run

Putting today’s Nasdaq level into historical context is a bit difficult. It has been so long since the last, lasting correction in the value of technology companies that their aggregate share price chart is simply up and to the right. Can you recall the last time tech stocks dropped real value, and stayed down?

Probably not. The reason why is that compared to the post-2008 expansion, the 2000-era technology bubble appears small, pathetic and short-lived. Via YCharts, here’s a look at the Nasdaq Composite going back into the ’80s:

That, in a nutshell is why there are so many unicorns in the market; that chart is why SaaS multiples are still around 10-11x ARR (per Bessemer, which is rebuilding its cloud index page at the moment). That chart is a part of why Uber’s valuation got ahead of its real value. It’s also why venture capital funds have gotten larger, private equity deals more expensive and SoftBank may raise a second Vision Fund despite a host of high-profile wobbles. It’s how Microsoft added mow than 50% of its total value this year.

You get the idea.

The stock market is incredibly strong right now, a fact that is pushing lots of private investors to pay more for growth in anticipation that companies’ revenue multiples will stay high (as dictated by public comps, or what larger companies are willing to pay for startups). So long as the Nasdaq keeps going up, that bet makes the punters look smart.

So what?

We could have written this post a few times in the past week, let alone this year.  Of course, we can’t post a similar entry every time a tech-focused index hits a new record high — you’d fine it repetitive. But we also can’t not mention it every time, as it is critical to recall that today’s warm climate for startups is predicated on a public market trend that will not — cannot — last.

When will things change? No one knows. So far this December there’s no mini-crash to worry about. Things just look good, and healthy, and flush with new records.

Instagram hides false content behind warnings, except for politicians

Instagram is giving politicians the same free rein to spread misinformation as its parent company Facebook. Instagram is expanding its limited fact checking test in the US from May and will now work with 45 third-party organizations to assess the truthfulness of photo and video content on its app. Material rated as false will be hidden from the Explore and hashtag pages, and covered with an interstitial warning blocking the content in the feed or Stories until users tap again to see the post.

This goes an important step further than Facebook’s early attempts to append warnings on links alongside content but that still let users immediately consume the misinformation. In October Facebook announced it would use a similar interstitial warning system.

Instagram will use image matching technology to find additional copies of false content and apply the same label, and do this across Facebook and Instagram content. That could become a talking point for Facebook as it tries to dissuade regulators from breaking up the company and spinning off Instagram. On the other hand, it’s a valuable economy of scale for protecting the internet. Breaking up Facebook, Instagram, and WhatsApp might lead to worse enforcement through fragmented resources, though it could lead the apps to compete for the best moderation.

Instagram is trying to beef up its safety practices across the board. Today it began alerting users that the caption they’re about to post on a photo or video could be offensive or seen as bullying, and offer them a chance to edit the text before they post it. Instagram started doing the same for comments earlier this year. Instagram is also starting to ask new users their age to make sure they’re 13 or over, which I’d previously written it needed to add since it was otherwise feigning ignorance to dodge Child Online Privacy Protection Act violation fines.

One group that’s exempt from the fact checking, though, is politicians. Their original content on Instagram, including ads, will not be sent for fact checks, even if it’s blatantly inaccurate. This aligns with Facebook’s policy that’s received plenty of backlash from critics including TechCrunch who say it could let candidates smear their rivals, stoke polarization, and raise money through lies. Instagram CEO Adam Mosseri has maintained that banning political ads could hurt challenger candidates in need of promotion, and that it would be tough to draw the lines between political and issue ads.

Instagram is luckily less dangerous in this respect because feed posts can’t directly link out to websites where politicians could raise money. But verified users can attach links to Stories, and everyone can have one link in the profile. That means false information could still be knowingly weaponized by politicians on the app further their campaigns at the expense of truth…and people’s perception that they can believe what they see on Instagram.
