Thanks @1invest
Here's the 48 mth cycle placed into a composite Index (RED line is the comp Index / BLUE line is price) - As you can see of late its been accurate, in the 2000's it was out of whack - 2008 INVERTED into a high or came early, I prefer the Inversion as when these cycles Invert they act (price wise) as its done in the spike to a high then collapse
Ideally we'd like much more price data to snip out the longer term cycles - For trading purposes, we can move down to the WEEKLY time-frame and run cycles off that chart to find the weekly cycles that move the Monthly charts etc
Although I personally prefer to wait for bullish confirmation of a low around the expected low date, employing a strategy of just buying long around these low dates is fine, as long as the trader/Investor is happy to have some heat on further price falls before it turns
I tend to do a set and partially forget with these types of trades and buy into an ETF for my SIPP and its usually an ALL IN purchase once the bullish confirmation comes in and its a min doubling expectation - Once I've double checked the cycles valid etc - there's structure to the purchase that I've not mentioned, so its not a blindly buy in and hope
This works great with stocks too if a stock displays cyclic patterns on these long term cycles - you buy in near the long term cycle lows and quickly double your money, obviously its not guaranteed, but it happens a lot over the decades - when I say quickly it takes months, but in the grand scheme of things etc
I doubt most Investors/Traders look out decades to see if any patterns exist, because they believe that markets are random and what's the point in wasting an hour scrolling through monthly charts etc, but it is very much worth while
I'm writing a journal on the Journal forum and at some point this year I had planned to write a few posts on the subject - but before I do I'm laying the ground work from easy to complicated and we're not there yet
