I've seen an argument made that it was wrong to track a potential breakout on TOTAL3ES or TOTAL3ESBTC by tracking the RTY breakout because the correlation coefficient on the 1M for TOTAL3ES and RTY has gone into negative for the first time and claiming they have de-correlated. Tracking correlation on the monthly chart is crazy because it can be an extremely lagging indicator esp. when comparing it to a volatile asset class! Now if you look at the correlation for RTY and TOTALES on the weekly instead, you can already see the correlation getting back above zero. You can see a similar dynamic before past alt runs too where the correlation dips below zero briefly. Correlations can change.
