What you're describing is the exact opposite of the oversold/overbought principles.

The market will value the company and the SP will follow. As the price falls more buy pressure builds, it's why you always see ranging in a share price. It never goes in straight lines up, down or sideways.

Make a decision on whether you're comfortable with the profit/loss the current price means to you, decide whether you think the near future direction is up or down and what that means to you. Make your own decision on whether the time frame is suitable for your particular situation.

Then sell or hold.

No-one can make these decisions for you, that's up to you.

Good luck.
