Looking at its own history, LFUS is currently trading cheaper than 100% of the last 5Y on P/E. This places it in the 0th percentile of its historical range, a level that has historically coincided with attractive entry points.
Our discounted cash flow model estimates LFUS's intrinsic value at $279.56 per share, against the current market price of $391.46. This implies a premium to fair value of -28.02%. The current price sits well above what projected cash flows justify, implying investors are paying for growth that has not yet materialized.
The Piotroski F-Score of 5/9 puts financial quality in a middling range, neither a standout strength nor an obvious red flag.
Bottom line: LFUS appears richly valued on our framework, with a Smart Value Score of 43/100. At current levels the risk/reward is skewed against the buyer. A materially lower price or significant operational improvement would be needed to change the picture.
