HIVE and STEEM Correlation

Looking at the last half a year hive has been very correlated with steem. This could allow people to make some interesting arbitrage trades if there is a pattern that emerges that either one flips the other frequently then you can buy the one that is lower and sell the one that is higher and wait for a reversion back to the middle area. Having both steem, hive and stables would be necessary to do this as well as a automated bot to find when the prices diverge enough to warrant a position. The same could be done with SPS and GLX or SPS and DEC etc to see if there are any patterns or use SPS and its market cap for some additional trading signals.
