Satellite Communication Stock Soars 800%, Drops 6% the Next Day

Shares of Viasat Inc. (NASDAQ: VSAT) closed at $81.44 on May 29, down 6.06%. Volume topped 3.57 million shares, and market capitalization stood at roughly $11 billion (about KRW 15.5 trillion), erasing approximately $630 million (around KRW 900 billion) in a single session. The stock had surged about 835% over the past year, nearing its 52-week high and stoking concerns of short-term overheating.

After the market closed the previous day, Viasat reported its fourth-quarter and full-year fiscal 2026 results, highlighting improvements in earnings and cash flow. However, its fiscal 2027 guidance fell short of investor expectations, triggering profit-taking. That same day, Barclays reaffirmed its equal-weight rating on Viasat and maintained a $49 price target, implying significant downside from current levels.

Headquartered in Carlsbad, California, Viasat provides residential, enterprise and in-flight internet; military satellite communications services; and satellite and ground terminal equipment. Its 2023 acquisition of UK-based Inmarsat expanded its footprint in the global satellite communications market, and contracts such as those with the U.S. Space Force have emerged as key growth drivers.
