Thermo Fisher Scientific Hits All-Time High of $694.33 Amid Guggenheim Buy Reiteration

Thermo Fisher Scientific shares reached an all-time high of $694.33 on October 15, 2026, as positive analyst sentiment continued to build around the life sciences company. The milestone came on the same day Guggenheim reiterated its Buy rating on the stock, reinforcing confidence in TMO's outlook.

Thermo Fisher also appeared among a batch of new initiations on October 15, alongside a broad list of tickers across sectors, signaling continued Wall Street attention to the name. The stock was also mentioned on CNBC's "Halftime Report Final Trades," where it appeared alongside Pfizer and others, though the featured trade from Short Hills Capital Partners chief investment officer Stephen Weiss was a U.S. 10 Year Treasury rather than TMO directly.
