Price 170.50 TWD · Downside -10.8%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then (4.71 TWD per share) are deliberately not added.Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.
Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card.62/100

What shareholders gained per year (last 5 years), in TWD ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate. Measured in TWD: this currency has depreciated against the euro and dollar over the long run, so part of the nominal rate is currency erosion that never reaches a EUR/USD investor.

Growth Forecast
A lot of optimism in the price
The price assumes more growth than the company has delivered so far.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).

After inflation (Taiwan: IMF forecast 1.6% a year to 2030, 1.5% from 2016 to 2025) that is about +52.8% a year for the price.

What is a reverse DCF?
A reverse DCF turns the usual calculation around. Instead of deriving a value from assumptions, it takes today's price as given and asks: what free-cash-flow growth would a company have to deliver for exactly this price to be fair? The result is not a forecast but the expectation already priced in. For Tai-Tech Advanced Electronics Co Ltd that is +55.2 % per year for five years, then slowing evenly to 2 % by year ten, using the same discount rate (13.0 %) and the same formula as our fair value.

When it exceeds the discount rate of our models (13.0 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.
