@Arbu, have you stopped what you were doing?
It seems to me that for whatever reason, you weren't able to assimilate enough of the technical bits and pieces , with a productive mindset, to do anything other than keep your pot on the downtrend.
Nothing I'm saying ever is recommendation, OK, so don't throw anything back at me again. All is up to you.
What you probably could do, which is what I've been trying/doing sort-of in the background, is watching momentum. By that I mean what's doing well, right now. There are lots of sector scanners for that. EG I wouldn't dump all my investments into highest tech right now, because it has been pretty choppy over the "few days" timescale. OTOH the FTSE has been trending up. China, India, Japan are worth watching. CHina large cap has generally been moving up recently, whereas India and Japan are showing better signs, but not much consistency yet. SImilarly, Utilities is the one sector (iirc) which has ignored the dips, and Financials is interesting atm..
EG (not a recommendation) If the FTSE does well for a while, watch out and as long as there's no sign of much changing, find as good a pullback as you can and put some money in it and keep a close eye on it. bear in mind the 0.5% tax (which will be there in the ETFs spread too , probably), and there's a good chance that it'll carry on up
some. The odds are in your favour.
You can use things like the MACD or Commodity Channel indicators to identify a short term dip. If you get it micro-wrong, the macro-uptrend will
probably recover you if you hold.
It's "the same" as day trading, but you have more time to reflect on your entries and exits, so you can be more considered and maybe less emotional.
Try it in the SIM for a couple of weeks. It's like swing trading, but only on a trend.
Stooging about I found Macdonalds, an often-suggested long term hold. I bought a tiny bit, I'm looking for a bottom. It's a bit slow, but has been ranging in the same rising channel for ~5 years. I don't know of any reason why it's reatively down now, reports say family budgets squeezed is all. They've released a $5 deal - sounds good.
It would be better to find something which didn't go down when the spy did go down, but these guys results were decent and good for their sector. Maccy D's are still very popular with US kids. The wave theorists seem to think they're near a bottom. No Sh.. Sherlock.
Come back in July/August...?
