Met 15 euro voor de aankoop van één aandeel is dit de duurste broker”: Pieter Slegers test 6 beursplatformen en geeft ze punten – HLN

Pieter Slegers identified a significant disparity in brokerage costs after testing six different trading platforms, finding that one provider charged 15 euros for the purchase of a single share. The analysis, reported by HLN on July 21, 2026, used a scoring system to evaluate the platforms based on pricing, usability, and accessibility for retail investors.

Brokerage Fee Disparities in Retail Trading

The cost of executing a single trade varies sharply across the six platforms tested by Slegers. According to the HLN report, the most expensive broker charged a 15 euro fee for one share, a price point Slegers highlighted as the highest among the group. This cost represents a substantial percentage of the total investment for retail traders purchasing low-priced stocks.

Slegers applied a point-based system to rank the platforms. This methodology focused on the friction points investors encounter when opening an account and the direct impact of transaction fees on small-scale portfolios. The results indicate that while some platforms offer low-cost entry points, others maintain high minimum commissions that can erode potential returns for those not trading in large volumes.

Analysis of Platform Performance and Scoring

The testing process involved a direct comparison of six brokerage services. Slegers evaluated these platforms not only on the raw cost of a trade but on the overall user experience. The scoring reflected how easily a user could navigate the interface to complete a purchase and the transparency of the fee structure before the trade is executed.

The HLN analysis suggests that the 15 euro fee is an outlier in the current market, where many “neo-brokers” have pushed for zero-commission or low-flat-fee models. The disparity suggests a divide between traditional brokerage services and newer digital-first platforms.

Impact of Transaction Costs on Small Investors

For an investor purchasing a single share of a company, a 15 euro fee creates a high hurdle for profitability. To break even on such a trade, the stock price would need to rise by 15 euros just to cover the initial cost of the transaction. This makes high-commission brokers impractical for those employing a “buy and hold” strategy with small amounts of capital.

The report emphasizes that the choice of platform can be as influential to an investor’s net return as the performance of the stocks themselves. Slegers’ point system serves as a guide to identify which platforms align with different investment scales, contrasting high-fee professional tools with low-cost retail apps.
