Therefore, I think C3.ai stock could trend higher -- potentially even toward its average P/S ratio -- if the company's upcoming Q2 report shows a further acceleration in revenue growth. If its P/S does reach its long-term average, that would imply an upside of 65% in the stock. Past performance doesn't predict future results, but C3.ai stock is trading 13% higher since reporting its Q1 results, which might bode well for its upcoming Q2 report. While there is reason to be optimistic about potential upside for C3.ai stock in the weeks and months ahead, investors should always focus on the longer term. AI could be a multiyear technological revolution, which C3.ai CEO Thomas Siebel compares to the dawn of the internet and the smartphone. Citing research by Bloomberg, Siebel believes the AI opportunity will be worth a whopping $1.3 trillion by 2032, so investors will have to stick around for the long run if they want to capture as much of that value as possible.
