Its stock fell about 17% on July 29. The AI infrastructure company's second-quarter earnings beat expectations, but its revenue fell short of Wall Street's expectations, and that was enough to sink the stock.Then the company's CEO went on television and told investors to calm down."This is a temporary issue," Giordano Albertazzi said on CNBC's "Mad Money." "Nothing has changed in the long term of our trajectory."That's a bold claim to make while the stock is down double digits.But it matters whether he's right. Anyone holding VRT has a stake in the answer, and so does the broader group of AI data center stocks riding the same buildout.What the Vertiv earnings report actually showedVertiv reported adjusted earnings of $1.52 a share, ahead of the $1.43 analysts expected, according to Yahoo Finance, Revenue came in at $3.27 billion, short of the $3.38 billion Wall Street predicted. So earnings beat expectations and sales still grew 24% from a year earlier. The problem was the miss on revenue, which came in roughly 3% below the target.For a stock priced for perfection, 3% was enough to cause a drop.Vertiv builds the power and cooling systems that keep AI data centers running.SOPA Images / Getty ImagesWhy a small revenue miss triggered a big Vertiv stock dropVertiv entered earnings trading at about 40 times its updated full-year profit guidance, Investing.com reported.At that price, investors expect the company to hit every number cleanly.When a highly valued stock misses even slightly, the selling tends to be sharp because there is little room built into the price for disappointment. That is what happened here.More AI Stocks:Overlooked AI stock is growing faster than Nvidia
