Thanks for the great reply. Indeed I am interested in you expanding more. I've been a long-term "valueish" investor, following the preachings of Warren Buffett for over 15 years. My long-term portfolio is pretty well balanced, Apple, to banks, to Berkshire Hathaway, Amazon, Ford, AMD, and SPY.
Recently, when the market got way overdone and oversold, I'd even call some of it panic selling with the bottoming happening Christmas Eve. I am curious how I can be more analytical, and data driven to make decisions during these events, rather than just gut feeling of panicking, negative news, and oversold conditions. Well I did add to my Apple position in this late December, I should have pulled the trigger more. I was somewhat conservative, missing the huge runup last month in January of most all stocks.
I can give some advice, but you should take it with a grain of salt :) I have been more of an infrastructure guy, and building the platforms with quants/traders, and not really trading myself. I am also more familiar with HFT trades overall.
I think you're on the right track regarding value investment, if you're thinking about it long-term, and it's for personal investments. Passive index funds like SPY are the best bet for most people. Finding companies or following trends you in particular have some insight on can also help. Things like "having worked in industry X, and having read their whitepapers, this new company is clearly overbought and is all marketing hype".
If you want to get more analytical, look at portfolio theory, different hedging strategies, and try and find "alpha" - roughly meaning the extra factors explaining the price of an instrument that gives you an edge over others. Check out Quantopian - they have some nice articles too. The key is coming up with a model that accurately captures the risk of your assets which would allow you to properly allocate your money amongst them.
