Netflix Plunge Deepens Nasdaq’s Correction

Netflix shares fell 22% after the company late Thursday reported slowing subscriber growth. It was the streaming giant’s biggest single-day drop since 2012. The stock was on pace for its biggest drop since 2012. Other streamers followed, as investors sized up their growth prospects in the face of Netflix’s news. Roku Inc., fuboTV and ViacomCBS Inc. VIAC -7.35% all retreated at least 7.4%. Even those outside of the Nasdaq fell, with Walt Disney Co. shedding nearly 7%.

Streamers and other tech stocks had already been falling prior to Netflix’s report, and investors say the pullback likely has yet to reach a bottom. The Nasdaq entered into a correction—defined as a drop of 10% or more from a closing high—on Wednesday.

“Monetary policy is no longer skewed in one direction: to ease. It’s just the opposite,” said Michael Rosen, managing partner at Angeles Investments. “We’re facing an enormous change of monetary policy we haven’t seen in a very long time.”

Although clients of his aren’t panicking, he has raised cash levels by selling stocks in recent weeks, Mr. Rosen added.

Thursday looked like it might deliver a reprieve for the group after the Nasdaq rose more than 1% in morning trading. However, it ended down 1.3%, marking the first time in more than 20 years that it erased an intraday gain of more than 1% and closed off more than 1% on back-to-back days, according to research firm Bespoke Investment Group.

The Nasdaq had been on the verge of a correction over the past two weeks, as the rapid run-up in bond yields and concerns about how quickly the Fed would tighten monetary policy to combat inflation eroded investors’ longstanding devotion to the tech trade.

About 72% of the stocks that trade in the Nasdaq are down at least 20% from their recent highs, a level that’s considered bear territory. More than half are down 40% or more.

Much of the selling has centered around unprofitable tech and other so-called stay-at-home stocks, many of which saw big gains during the first year of the Covid-19 pandemic. As the market confronts the prospect of a series of rate increases, along with the fast rise in bond yields, the valuations for those stocks have fallen as analysts and investors factor in the prospect of lower cash flows.

Companies like Zoom Video Communications Inc. and DocuSign Inc. are down at least 20% this month, and at least 58% over the past six months. Peloton Interactive Inc. has fallen even further amid slowing sales and a report Thursday, contested by its chief executive officer, that the fitness company was temporarily halting production of its connected-fitness products. Shares are down nearly 80% over the past six months, but were up 12% Friday as investors bought the dip.

Despite the dip-buying in Peloton, analysts and investors said they don’t expect to see a broader sustained rebound yet. The picture on interest rates and how aggressively the Fed will move to contain inflation remains fuzzy, some said.

“We have a preference for cyclical sectors, such as energy,” wrote Mark Haefele, chief investment officer of UBS Group AG’s global wealth-management arm, in a Friday note to clients. “In technology, we have advised investors to be more selective.”

Investors who have been buying the dip so far have mostly felt more pain. Cathie Wood’s flagship ARK Innovation ETF has been adding to some positions in January, including buying more shares of Roku and telemedicine company Teladoc Health Inc., another pandemic favorite that has been beaten down this year. Her fund is down 24% in January, trading at levels last seen in June 2020. The ETF fell 5.7% on Friday.

“This is the most complex time to be an investor,” said Nancy Tengler, chief executive and chief investment officer at Laffer Tengler Investments. “As always, once the volatility starts, investors pile on.”
