Natural way of expressing changes in percentages in the financial markets

Observing the gyrations in the stock market, at some point today the NASDAQ was up 0.30%, and as I tried to verbalize this figure, I realized how unnatural it is to say "it is up zero point three percent." OK, it may not be that bad, but what about the Dow being up right now "0.11%". Do people in finances say "up point eleven percent"? Do they revert to fractions?

• I think I just got the answer after entering the right Google search query: Basis points. So 30% up would be "up 30 basis points"? There may be other ways, so I'll leave the question up. – Toni Feb 6 '18 at 18:23
• You are right. BPS (basis points) is the common unit for expressing changes. But the conversion goes like this: 1 basis point equals 1/100%. So 30% up will be 3000 basis points. 0.3% is equal to 30 basis points. – Kannan Feb 6 '18 at 18:52
• Up eleven percent is 11/100 not 11/10,000. You can go with approximate fractions (1/10 of a percent) or basis points (11). Either way, we're not going to brag about the gain ;->) – Bob Baerker Feb 6 '18 at 18:53
• @BobBaerker Re: 11%, and to avoid confusion, I wrote "point eleven", meaning 0.11%. I wonder if the "point" part was overlooked in your comment. – Toni Feb 6 '18 at 19:14
• @just questions - 0.11% is expressed as point one one percent not point eleven percent. – Victor Feb 6 '18 at 21:22
