Hey man,
Some of this will be useful when researching other sectors, but I am geared towards the resources sector, so this will be mainly about finding stocks within that sector.
I have only been investing in the spec stocks for a year and the way I track momentum in sectors is multiple things. First I keep an eye on price movements in metals I usually use
http://www.infomine.com/investment/precious-metals/ , obviously if the price of a metal is going up then stocks in that sector should go up as well. Infomine also has the top companies gainer/losers in metals across the global and also for individual metals just got to choose which metal you are interested in. Next I use
http://www.rsc.org/periodic-table/ which tells you the supply risk of elements, I mainly use this to get a basic understanding of that the element is used for and then I can decide if I think it will be needed/has a big supply risk in the near future. Next After I have found a metal I think is going to be hot, I will go to the ultimate guides on
https://*********.com.au/nickel-stocks-asx-ultimate-guide/ the rest of the guides are at the bottom of the page. ********* also has a good amount of info on everything in the asx ********* world, very useful. After I have found a couple of companies that I think are good I put them all on a watch list. I also have a twitter account for the purpose of following people I respect in the trading market and also for following websites like *********, *, HC and multiple others. The trick is not to overload yourself with info, what I want when I scroll down my twitter is an overview of the stocks/metals I am invested/interested in and an overall feel for where the market is going. What I don't want is a whole heap of people trying to sell me some company. Another website I have found useful is
https://www.bullmonitor.com/ it monitors the most twitted/HC commented stocks, so it is a good way to see what people are talking about. Anyway I have only been doing this for a year and hope some of this helps
