ΣL Cycle Summary
This excellent periodic feature in Lithium, which we have tracked for several months now on Sigma-L, is due the next trough iteration shortly. We can observe some dwindling power of the wave during the larger downtrend but stationarity in frequency is well maintained. This is shown in the time frequency plots by the absence of any surrounding power in the vicinity of the main feature, around 80 days. Bulls will hope for an increase in power as the next trough is established and price moves back up into mid August.
