A DCF process is not finished when price reaches fair value. That is exactly when the investor needs discipline. The original thesis may have played out, the business may have improved, or the market may have moved beyond the evidence. MyLinedChart can help keep the exit decision connected to the original valuation work.

Quick Answer

When price reaches DCF fair value, the investor should review whether the original thesis is complete, improved, weakened, or still underpriced. The decision should not be automatic, but it should be structured.

Fair Value Decision Rules

A fair value zone should trigger review, not emotion. The investor should know which evidence would justify holding beyond the original valuation and which evidence would justify trimming or exiting.

MyLinedChart can preserve the old thesis note next to the current price zone so the investor can compare intent with reality.

Fair value should start a disciplined review, not end the thinking.
Situation	Review Question	Possible Decision
Price reaches base fair value	Did the thesis simply play out?	Trim or exit
Business quality improved	Did fair value move higher with evidence?	Update model and hold
Price outruns evidence	Is upside now mostly multiple expansion?	Reduce exposure
Catalyst still pending	Is expected value still attractive?	Hold with review date
Thesis weakened	Did price hide a business problem?	Exit or rewrite thesis

Avoid Thesis Creep

Thesis creep happens when the investor keeps raising the story only because price keeps rising. The antidote is a written decision trail that shows the original valuation, the current evidence, and the new fair value if one exists.

If the model cannot justify the new value, the investor should admit that the position has changed from value to momentum or sentiment.

FAQ

Should investors sell when price reaches DCF fair value?

Not automatically. They should review whether the thesis is complete, whether business evidence improved, and whether the revised expected return is still attractive.

What is thesis creep?

Thesis creep is when the investor keeps changing the story after price rises without new evidence that supports a higher fair value.
