They’re mathematically designed to decay and both go down over time, unless there is persistent trend/direction. Without a trend (financials being volatile and going up and down) they’d both decay to nothingness.
Answer is straight forward. Both starts with F A. Z is voiced. S is voiceless. (phonetics). That is why there is correlation
agree. I looked at the 10 year performance, factoring in all the market pops & drops along the way till EOD yesterday. Approx $1800 loss on a 10 year hold on the total $20k investment. FAS growth with splits you'd have $18,135 on the $10k original investment FAZ growth/decayed with reverse splits/consolidations ended to $61 on the $10k original investment. https://www.stocksplithistory.com/?symbol=fas https://www.stocksplithistory.com/?symbol=faz the FAS/FAZ pair buy & hold is a losing investment
%% Both trend sloppy; even though FAS has had some good uptrends above 200 day moving average.I cut a 3% loss on FAS + good riddance;when I was in it, it moved up worse than my other longs
