EchoStar (NASDAQ: SATS) landed in the S&P 500 on March 23, 2026, and it arrived with baggage: 21.5% of its float is sold short. That combination is rare. Passive index funds are now structurally obligated to buy and hold the stock as long as it remains in the index, while a meaningful portion of the market is betting against it.
Why the S&P 500 Matters for Shorts
Index inclusion creates sustained demand. Every dollar flowing into S&P 500-tracking ETFs and mutual funds buys EchoStar shares. As the index rebalances and new money enters, passive funds must continuously hold the stock. For short sellers, that sustained structural buying pressure cannot be outrun simply by waiting.
The short interest data underscores how uncomfortable that position is. Days to cover stand at 7.68, meaning shorts would need more than a week of average volume to fully exit. The peer group average short interest is 19.5%, so EchoStar’s short interest is notably higher. Short interest increased 4.23% from the prior January 2026 report, suggesting bears were adding into the inclusion announcement rather than retreating.
The stock has already punished shorts severely, with shares up 312.4% over the past year. Anyone short through 2025 has absorbed enormous losses.
Why Shorts Were There in the First Place
The bear thesis is not irrational. Forward EPS is −$52.93, making EchoStar deeply unprofitable. Its legacy businesses, including DISH TV, Sling TV, and HughesNet, are in structural decline. A securities investigation was launched by Robbins Geller Rudman & Dowd in June 2025 regarding potential federal securities law violations. Insider selling has been aggressive: CEO Hamid Akhavan sold 71,005 shares on March 6, 2026, while COO John Swieringa disposed of 50,088 shares at prices near $113 to $114 on March 4, and CLO Dean Manson sold 19,031 shares near $114.50 to $114.60 on March 5.
What Changed the Thesis
Two spectrum deals rewrote the story. AT&T has agreed to buy EchoStar’s spectrum for approximately $22.65 billion, pending regulatory approval, with an expected mid-2026 close. Separately, SpaceX agreed to purchase AWS-3 licenses for approximately $20 billion plus $2.6 billion in SpaceX equity. Morningstar raised its fair value estimate to $120, calling EchoStar “increasingly a bet on SpaceX.” The SpaceX equity stake represents optionality ahead of a potential IPO. Analyst consensus sits at $129.60, with three Buy ratings, two Holds, and one Sell.
The Counterargument Remains Real
The AT&T deal is not closed. Regulatory approval is not guaranteed, and the bear case survives if the deal collapses. Insider selling at current price levels signals that management sees fair value closer to where the stock trades today than where bulls project. Reddit sentiment scores a bearish 28, with the most-engaged post referencing a SpaceX “rug pull” in the space sector.
The conditions for a squeeze exist. The AT&T deal closing is the catalyst that determines whether those conditions trigger one.
