FORTUNE — I’ve long since given up on Google GOOG  as fair arbiter of business news value (see Has Google Finance’s news feed got it in for Apple?). I’d assumed, however, that it could be trusted to deliver accurate market data.

But reader Hank Vaccaro points out that according to Google Finance, Apple’s AAPL $450 billion market cap was eclipsed overnight by the $1.03 trillion valuation the site assigned to Regis Corp. RGS , the world’s largest hair salon chain.

Yahoo Finance puts Regis’s market cap at $1.03 billion. That sounds more like it.
