IG Group shares plunge 25% as Peel Hunt flags revenue and margin downgrade

IG Group shares fell nearly 25% to 962p after the online trading firm cut its 2026 revenue-growth outlook to mid-single digits, versus prior guidance of 10%-15% and roughly 12% market expectations. Peel Hunt said the weaker outlook could trigger a high-teens percentage reduction in consensus earnings forecasts; it retained a hold rating and 1,100p price target.

Analysis

The key equity issue is not the lower top-line trajectory itself but operating leverage: IGG’s largely fixed technology, compliance and marketing base means a mid-single-digit revenue path can translate into a disproportionate EPS and free-cash-flow reset. The market will now question whether the prior growth algorithm was structurally overestimated, which can sustain multiple compression beyond the initial estimate cuts; a one-off reduction is investable, but a second downgrade to FY27 assumptions would recast the stock as an ex-growth yield vehicle.

Near term, the likely pressure point is a rolling sell-side de-rating cycle over the next 2-6 weeks, particularly if management does not quantify expense flexibility, client-acquisition payback, and the mix between higher-margin OTC activity and lower-margin exchange/stock trading. CMCX and PLUS are useful read-throughs, but should not be assumed to have identical exposure: relative performance versus those peers will distinguish an IGG-specific execution/client-retention problem from a broad retail-trading activity slowdown.

The contrarian case is that the initial price adjustment may already discount much of a high-teens EPS reduction if capital returns remain intact and the lower outlook reflects deliberately reduced marketing spend rather than deteriorating client economics. That thesis is falsified by declining active-client metrics, a material cut to dividend/buyback capacity, or evidence that revenue growth remains below mid-single digits after volatility normalizes. The next 1-3 months should be treated as an estimate-reset period; the 6-18 month upside case requires proof that incremental revenue can again convert at historical margins.

Key Decisions for Investors

• Maintain an underweight/short bias in IGG through the next formal trading update or consensus-reset cycle; use a rebound toward 1,050-1,100p as a better entry zone rather than chase the gap down. Target a further 10-15% downside if FY26 EPS estimates fall by the indicated high-teens amount; cover if management demonstrates cost offsets sufficient to limit EPS erosion to less than 10%.
• For market-neutral exposure, consider short IGG versus long PLUS or CMCX only after confirming peer client-activity and revenue commentary. The trade isolates an IGG-specific execution reset, but should be avoided if both peers signal broad contraction in leveraged retail trading volumes.
• Do not underwrite a dividend-support long solely on the post-drop yield. Require confirmation of net cash, regulatory-capital headroom, and unchanged shareholder-return guidance; a capital-return reduction would remove the principal valuation floor.
• Set alerts for active-client trends, net trading revenue per client, marketing spend as a percentage of revenue, and FY27 consensus EPS. A second guidance reset or sustained peer outperformance over the next quarter supports the short; stable client monetization and margin preservation would warrant closing it.
