Thoughts on FI and the 'AI Premium' – Is it Sustainable?

Been watching $FI today, trading around 63.8, up slightly on the day from its open around 62.67. It's a solid company, no doubt, but the current valuations across much of the tech sector, especially those even tangentially related to AI, feel increasingly stretched. We've seen this narrative before – good companies get a 'premium' tacked on because they're in the right space at the right time. The move from 62.67 to 64.18 today isn't huge, but it's another tick up in a longer trend.

My concern isn't about the fundamental business of a company like Fiserv, but rather about the market's enthusiasm being priced in a bit too aggressively. The argument for continuous upward movement often leans heavily on future growth projections that might be optimistic. It makes me wonder if we're seeing another cycle where the 'AI premium' is starting to overshadow the underlying financial metrics. I'm keen to hear if others are viewing this similarly, or if I'm missing something crucial in this current market dynamic. Is this truly sustainable, or are we just setting up for a sharp correction when the narrative shifts? Push back if you think I'm off base.
