There are very large funds that focus on tech. And since tech has gotten so big relative to the market, even if a fund doesn't specialize in it, they still have to understand it.

Since they have so much money at stake, they have an interest in understanding it. Not doing so will cost them their jobs.

"Understanding" is "in the financial sense" of course. They mostly care about the volumes of money going in and out, and expectations for that.
