I plot the difference in prices of two S&P 500 tracking ETFs, SPY and IVV.
There are predictable and pronounced spikes in the middle of every March, June, September and December.
Do you think it is just an illusion?

Hello Yawer,
I plotted the difference as a percentage of the average price of the two ETFs. The dips are fractions of a percent--seems like it'd be hard to realize a gain (assuming that the differences are real).
