Trouble is with tips and analysts you get a tip and the market makers mark up the price and then it drops back later.
As for analysts they fall well short and self analyst is the best path to go down.
I think you are right about following winners and cutting losers its important though to watch mms cos many a shareholder has been hit with stop losses through market maker jiggery pokery by simply marking down for no reason !
Small companies can be volotile so some allowance has to be made there.
