Everyone is currently talking about Novo Nordisk - and many are buying it after the massive price drop because the share is now supposedly "cheap".
But be careful: a price drop of -70 % can be a bargain - but it doesn't have to be.
At the end of July, Novo Nordisk collapsed after a forecast reduction by a further 33 %. The new price simply reflects weaker growth and new risks - not necessarily an undervaluation.
The crucial question:
How do I find out whether a share is actually cheaply valued - or whether the market has simply become more realistic?
There are several approaches to this. One of the most popular - and in my opinion the most sound for many investors - is the discounted cash flow method (DCF).
📌 Important:
- The model cannot macro events (interest rate shocks, recessions) or political surprises - such as a sudden price cap on 🍊 medicines.
- A sharp fall in prices can trigger a short-term technical countermovement (rebound) in the short term - this can be interesting for traders. But for long-term investors, the decisive factor is whether the share is fundamentally is undervalued.
💡 Why DCF?
DCF analysis is so popular because it not only looks at current key figures such as P/E ratios or price/sales, but also evaluates the true core of a share:
How much money will this company earn in the future - and what is this cash flow worth today?
The model forces you to make all important assumptions openly:
- expected sales growth
- profit margins
- Investment requirements (CapEx)
- capital costs (WACC)
- and a long-term, realistic growth target (terminal growth).
Although this makes DCF somewhat more labor-intensive than simply "comparing the P/E ratio with the industry average", it provides a company-specific fair value. company-specific fair value instead of just a relative market opinion.
🤨 Sounds complicated?
There are ready-made spreadsheets for calculating the DCF where you have to enter current data manually.
It's easier with AI.
Particularly capable models such as ChatGPT-o3 or "deep research" (ChatGPT, Gemini, etc.) do not provide an infallible analysis (always double check), but they do research the necessary data for you.
✏️ DIY-Prompt (Disclaimer: Can produce widely varying results - I am working on a more detailed prompt with more clearly structured specifications)
"Calculate a 5-year DCF for [ticker] based on the latest quarterly figures, with WACC 7%, terminal growth 2% and show me a sensitivity analysis for WACC ± 0.5 pp."
🔍 Mini glossary for the prompt
- Last quarterly figures: Starting point for your cash flow estimate - real, fresh data instead of old annual figures.
- WACC (Weighted Average Cost of Capital)The average return required by all investors - your discount rate.
- Terminal growth (g): Long-term "perpetuity rate", usually 1-3 %, so that the model remains conservative.
- Sensitivity WACC ± 0.5 ppTests how much your fair value rises or falls if the discount rate changes by half a percentage point.
📌 DCF analysis results of 3 examples:
📉 Novo Nordisk $NOVO B (+1,26%)
- Share price ≈ DKK 309 (-66% from high)
- Forecast 2025: revenue +8-14 %, FCF DKK 35-45 bn (≈ USD 5-6 bn)
- ⚖️ DCF fair value: ~ DKK 315 → practically fairly valued to slightly undervalued
- Braking factors: Regulated pharma market, price pressure, production capacity & patent dependency - earnings surprises more difficult than in tech.
Alphabet $GOOGL (-2,86%)
- Share price ≈ 190 USD
- Q2 revenue USD 96.4 bn (+14 %), TTM-FCF USD 66.7 bn
- ⚖️ DCF fair value210-230 USD → 10-20 % undervalued
- Plus points: Scalable advertising & cloud models, free pricing, network effects → slightly positive earnings beats.
☁️ Microsoft $MSFT (-3,8%)
- Share price ≈ USD 525
- Q4 revenue USD 76.4 bn (+18%), Q4 FCF USD 25.6 bn despite high AI CapEx
- ⚖️ DCF fair value580-620 USD → 10-15 % undervalued
- Plus points: Subscription margins, cloud scaling, pricing power (Copilot), even gigantic investments pay off quickly.
🧩 Core takeaways
- Share price decline alone does not make anything cheap. Novo Nordisk fell sharply, but is now only fairly valued - not a sell-off.
- Tech can be attractive despite high share prices. Alphabet & Microsoft are still trading below their intrinsic value because enormous cash flows support growth.
- DCF brings clarity. Only when market price is significantly below DCF fair value is and you have a margin of safety then "buy the dip" really makes sense.
