Price action = sentiment. Buy sell or hold are the only determinations of sentiment and the number on your screen is the score.
There fore control the price action you also control sentiment.
So I guess you could say sentiment is the sum of market forces at a given, if your personal sentiment is at odds with the the market you are going to have your arse kicked unless you have the muscle to change market.

If an analyst reports oversupply and the broker at the desk opposite deploys considerable means to cripple the price its just bs market activity that really has very little to do with the lithium story but it will change sentiment and as a small fish you can only go with the flow.
