I reported this bug over 5-6 months ago and still haven't seen it fixed.
For some reason, the investment section is not recognizing the correct stock symbol as being reported by Fidelity for the UHAL/B stock symbol. Instead it's pulling the stock price and data for the UHAL stock symbol. It would be nice to see this fixed sometime soon so my gains are accurate and not skewed because QS is pulling up the wrong stock symbol!
