Wondering why on someday xiv did not track vxx correctly?

I thought everyday XIV should gave similar absolute return compared to VXX. But my backtest shows one day there's a big difference. Where did I go wrong? I've attached a simple backtest. Need your help guys.

I think you hit the nail on the head. It attempts to track it, but it isn't totally successful.

@Viridian It's a 4% vs 8% return.

I don't understand what you need help with.

They're offered by two different companies. XIV is Credit Suisse. VXX is Barclays. They don't necessarily employ exactly opposite methods of tracking VIX. In addition, all ETFs and ETNs can stray from their NAV.
