If you're the type of trader who pays attention to momentum indicators, a couple of communication services stocks might be worth watching closely right now. As of December 24, 2025, both New York Times Co. (NYT) and Array Digital Infrastructure Inc. (AD) are flashing overbought signals that could matter for short-term performance.
The Relative Strength Index, or RSI, is basically a tool that measures how strong a stock is on its up days versus its down days. Think of it as a momentum thermometer. When the RSI climbs above 70, conventional wisdom says the stock might be overbought and due for a breather. It's not a guarantee of anything, but it gives traders a sense of whether a stock has gotten ahead of itself.
New York Times Co.
New York Times (NYT) has had quite a run lately. On December 23, Citigroup analyst Jason Bazinet maintained his Buy rating and bumped the price target from $72 all the way up to $81. That kind of analyst enthusiasm tends to get noticed.
The numbers tell the story: The stock has climbed around 11% over the past month and recently hit a 52-week high of $71.07. The current RSI reading sits at 79.3, which is well into overbought territory.
Shares of New York Times edged up 0.3% to close at $70.71 on Tuesday. The stock carries a momentum score of 82.74, though its value score comes in at a more modest 49.71.
Array Digital Infrastructure Inc.
Array Digital Infrastructure (AD) has its own momentum story to tell. Back on November 7, the company reported better-than-expected quarterly sales, and management sounded pretty upbeat about it.
"We are off to a great start as an independent tower company," said Doug Chambers, Array Interim President and CEO. "The new T-Mobile MLA commenced on August 1, and the team has been doing an outstanding job on the implementation effort. This new MLA drove a 68 percent year-over-year increase in Site rental revenue, excluding non-cash amortization. We have also made great progress monetizing our spectrum as we entered into additional agreements to sell our remaining spectrum and have now closed or signed agreements to monetize 70 percent of our spectrum portfolio."
The stock has responded accordingly, gaining roughly 15% over the past month with a 52-week high of $79.16. Its RSI currently stands at 73.2, above that 70 threshold that suggests overbought conditions.
On Tuesday, shares of Array Digital Infrastructure dipped 0.2% to close at $53.60.
For momentum traders, these RSI readings are worth keeping an eye on. Overbought doesn't automatically mean a stock will fall, but it does suggest that the easy gains might already be priced in. Whether these stocks take a breather or keep climbing depends on whether the fundamental stories can justify the momentum.
