Why Does BELFA Stock Spark Debate?
Founded by 26-year-old Elliot Bernstein during the electronics boom after WW2, Bel Fuse (NASDAQ: BELF.A) provides electronic systems and devices to the telecommunications, networking, transportation, and industrial sectors.
Two Positive Attributes:
1. Outstanding Long-Term EPS Growth
Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
Bel Fuse’s EPS grew at 47.7% compounded annual growth rate over the last five years, higher than its 7.7% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.
2. Increasing Free Cash Flow Margin Juices Financials
If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.
As you can see below, Bel Fuse’s margin expanded by 11 percentage points over the last five years. This is encouraging because it gives the company more optionality. Bel Fuse’s free cash flow margin for the trailing 12 months was 10.2%.
One Reason to be Careful:
Lackluster Revenue Growth
We at StockStory place the most emphasis on long-term growth, but within industrials, a stretched historical view may miss cycles, industry trends, or a company capitalizing on catalysts such as a new contract win or a successful product line. Bel Fuse’s recent performance shows its demand has slowed as its annualized revenue growth of 2.7% over the last two years was below its five-year trend. We’re wary when companies in the sector see decelerations in revenue growth, as it could signal changing consumer tastes aided by low switching costs. 
Final Judgment
Bel Fuse has huge potential even though it has some open questions, and with the recent surge, the stock trades at 32.8× forward P/E (or $221.95 per share). Is now the right time to buy? See for yourself in our comprehensive research report, it’s free.
