If you follow the analyst and market sentiment, you will be with the TREND & after all TREND IS YOUR FRIEND. If you stay alone with your decision, you will definitely miss the trend. Only real long term investors can stay alone with there solo decision.
For trading do your home-work but also stay tuned with analyst and market sentiment. But you have to differentiate who are real analyst and anal-shit. You can differentiate them by analyzing there predictions which got materialize in the prospective study.
Rest is your decision because no one is sharing there profit with adviser. Its bullshit to blame others if you incurred loss.
