if a stock with 130m cap is down on low volume so essentially a fake drop and you want to unload a motherload of shares when it is down 4% and a large order buyer wants to purchase bulk would they buy above the bid price by 4% or more
You would be playing a guessing or timing game.
It don't work that way. If I were you, I would look into
Fidelity's Bio-tech fund (FBIOX) Outstanding returns.
