The index has risen in price by X points…..

I do not understand what semantic and informational load is carried by the message that the index has risen / fell in price by a certain number of points? Еду, for example, cycling with headphones, listening to the radio, say CP added five points, Nasdaq девять пунктов, Dow30 twenty pips. Well, it doesn't tell me anything at all — a lot of it, a little bit? Which index looks stronger today? Can not understand anything. I have to remember which index is how much and correlate these increments with the value of the index., better, certainly, on the calculator — then the situation, maybe, will clear up. And not only on the radio — in some terminals indexes, реально,  during the day, are monitored only in points. Для кого это сделано, unclear. Russian terminals and exchange information facilities are more advanced in this matter. — always write as a percentage. Understandably, plain and simple. I suspect these point traditions are the legacy of sex traders with three grades of education., traded in the pits of Chicago and New York, who had to show everything on their fingers and percentages for them are the same as for me integrals and logarithms :)
