London Stock Exchange Group (LSE:LSEG) Stock Could Trade At A Premium Following The Octus Deal

London Stock Exchange Group has delivered a 39.7% share price gain over the past 5 years, which puts a spotlight on whether the current price still lines up with the returns the business earns on its capital. With the stock recently closing at £91.86 and fresh corporate moves in play, investors are asking if that track record of value creation inside the company matches the valuation outside it.

• Over 5 years, a 39.7% return means long term holders have seen meaningful value creation. The open question is whether those returns on capital inside London Stock Exchange Group justify where the share price sits today.
• The planned US$3.54b cash acquisition of Octus, alongside higher medium term targets for revenue, profitability and free cash generation, can reshape how efficiently London Stock Exchange Group puts new capital to work and how long it takes for that spending to translate into shareholder returns.
• If you'd rather focus on earnings, this one's for you. See what London Stock Exchange Group's 31.1x P/E says about the price.

The stock's next move may depend on whether the returns London Stock Exchange Group earns on its capital are strong enough, and durable enough, to support the current market valuation.

Is London Stock Exchange Group Getting Expensive on Excess Returns?

The Excess Returns model looks at what London Stock Exchange Group earns on shareholders’ equity above its estimated cost of capital. The inputs here point to a business expected to keep generating returns above that hurdle, with a stable EPS assumption of £5.51 per share against a cost of equity of £3.58 per share and an excess return of £1.93 per share. Average return on equity sits at 13.87%, while book value is put at £37.63 per share and nudged slightly higher in the steady state to £39.69 per share, both based on estimates from 8 analysts.

That profile means the model treats London Stock Exchange Group as a company that can reinvest at returns above its equity cost. However, the Excess Returns projections put the estimated intrinsic value meaningfully below the current share price of £91.86. The planned US$3.54b Octus acquisition and raised 2026 guidance help explain why the market is willing to pay up for the stock despite what this valuation framework suggests.
