It looks like it might be in the top 100 though. Considering these are changes per day, and the chart covers around 100 years or 25,000 trading days, this puts it in the top 0.4% of largest percentage daily losses. So, it does appear to be a significant losing day if 99.6% of such days are smaller in magnitude.

It's also significant given the overall state of the market.

Even accounting for an overall growth trend (e.g. real GDP) the market is looking quite overbought and prepared for a major crash. Signs of weakness like this are significant. It certainly doesn't guarantee a crash, but it's newsworthy IMO. Especially in the context of a decade of QE and the fed raising rates.
Dow has more up days than down. So among down days this is closer to 1% than 0.4%.
But then you could compare a different day and say it's in the top 200. Or the top 300. At which point does "X falls within top Y" no longer means anything?

About 0.3% of days are my birthday.

Despite the downvotes, the point seems valid on its surface. We should expect a losing day this bad or worse more frequently than once per year, which doesn’t sound that scary.
On the other hand, I wouldn’t expect losing days to be evenly distributed (in the short to medium term at least) but rather clumped together.
