You’re predicting the future what, 20, 30, 40 years until you retire?!
If you really want to forget all about your savings, or just pay in £X a month, then traditionally XLK (tech) would give best returns.
If you’re going to look at it at all, then I would say it all depends how frequently.
What I do is look at the screeners at the big fund holding co’s (AJ Bell, ii, Fidelity etc) to see which fund or sector has been doing best over the previous week, 3/6/12 months. Make a table in a diary. T212 is fine for some things, except there’s no screener.
Going back a year or so that has been India, running at 55% pa. I use that, but keep looking. Other sectors come to the fore, but some very briefly. There have been, usably, the tech sector, semis, Japan, small cap US, Utilities, and real Estate, in about that order. India has dropped to around 45%, whereas say the better Real Estate fund/ETFs have been getting me 3% a week. There are always corporate binds, with one I use at 25%pa, pretty steadily. Oh yes and the SPY 500, but there is almost always something better over a period of a month or so.
I used KWEB (China) for a while but it didn’t stay long enough. The others have been OK though.
If something goes too flat I sell it. It takes a few days to “settle” in a fund holder, but when it does it’s quick to jump into something on the rise with the freed-up cash. I assess how long something has been doing well, and what the catalyst is, such as the 0.5% rate drop.
Not everything is on every platform, but there’s usually something on T212. (Not a great India ETF/P, or range of shares, sadly, but look at ICICI bank).
I have used NVD3 for a few weeks when it’s been imitating a mountain goats, but those need watching .
A monthly adjustment, with a couple of mid month extra sells, would have got me 70+% this year without anything leveraged.
If I have sold a couple mid month if they’ve finished a good rise, it gives more time to look around.
I bought some SABRA at start of month, now up 10%. If I sold it now, well 10% in a month is OK. It’s on T212, so that one’s quick.
I tend to keep checking, so eg, another swingable R.E. related one is NAIL That’s only available on T212 on CFD though, which costs too much to keep overnight.
At the moment I have a mix of mostly India, Real Estate, and Utilities because they’re currently beating India.
Everything is on the phone of course, so for me the idea of leaving and forgetting is arcane.
