443018 impressions with a click through of 0.37% leading to a 0.29% install conversion rate would be awful be most apps... but you're targeting a tiny niche market - "people with money to buy shares who want a 'free' app to track their portfolio" are going to be incredibly rare. People who bother to track their shares tend to own a lot of them, so a $20 app isn't a problem. Plus, iPhones come with a stock tracking app installed, albeit a bad one, so you've got to get past that too.

I'd hazard a guess that your banner ad is actually very good and is attracting lots of attention, but the product isn't something many people want, hence lots of clicks but few installs. Maybe CPC marketing was a poor choice.

Thanks! Why though would people click on the ad which is clearly about stocks, if they don't want a stocks app?

It's difficult for me to understand this.
