IG Group Holdings (LSE: IGG) has secured its place among Britain’s largest listed companies after joining the FTSE 100 index in March, following roughly two decades in the FTSE 250.
The investment and trading platform operator finally achieved a market capitalisation large enough to warrant inclusion in the prestigious large-cap index.
The company operates a business model that allows it to generate revenue regardless of whether markets are rising or falling, giving it a structural advantage over many peers.
When markets climb, investors and traders tend to be more active in an effort to capitalise on gains, driving higher platform volumes and transaction revenues.
When markets fall, trading activity can also remain elevated as participants take profits, rebalance portfolios, hedge positions, and buy dips at lower prices.
IG is also well positioned to benefit from long-term retirement investing trends in the UK, offering both Stocks and Shares ISAs and SIPPs through its main platform.
The company also owns Freetrade, an investment platform that similarly offers Stocks and Shares ISAs and SIPPs, broadening its reach across different segments of the retail investing market.
That diversified positioning has translated into considerable momentum heading into 2026, with IG raising its annual and medium-term revenue forecasts for the second time this year following strong first-quarter performance.
Market volatility boosted Q1 organic revenue, and the company now expects organic revenue growth of between 10% and 15% for 2026 as a whole.
In the medium term, IG is targeting sustained organic revenue growth of 10%, signalling management confidence in the durability of its current trading environment.
Beyond its growth credentials, IG is also a highly profitable business, carrying strong gross profit margins, operating profit margins, and a high return on capital employed.
Companies with high returns on capital employed can often compound their growth significantly over time, making IG’s profitability metrics particularly relevant to long-term investors.
The stock also offers income, with a dividend yield currently sitting at around 2.6%, alongside an active share buyback programme that further returns cash to shareholders.
On valuation, assuming earnings growth of 10% this year, the stock trades at a price-to-earnings ratio of around 15, a modest premium to the broader market average.
Analysts at Barclays have recently raised their price target on the stock to 2,010p, suggesting they expect the upward trajectory to continue.
Risks do remain, including growing competition from platforms such as Robinhood and the possibility of a prolonged equity market downturn reducing retail interest in investing.
A sustained bear market could dampen trading volumes and weigh on revenues, which remain sensitive to broader market sentiment and volatility levels.
Nevertheless, the combination of a resilient business model, improving revenue forecasts, strong profitability, and a reasonable valuation makes IG Group a stock that appears worthy of further research for investors weighing their options.
