Bold claim: Drip-feeding £500 into the FTSE 250 could transform your retirement prospects. But does it really hold up? This rewritten version keeps the core ideas intact while improving clarity, expanding with practical context, and inviting discussion.
Investing in the FTSE 250 has delivered solid returns over the past decade. On average, it has produced about 5.4% annually since late 2015, which generally outpaced leaving cash in savings. In recent years the index has sped up, with double-digit gains over the last 12 months.
So, is now the moment to target long-term wealth by buying mid-cap stocks? And can a return figure like 5–10% annually be enough to build a sizable retirement fund? Let’s break it down.
Recent performance snapshot
Since late 2022, the FTSE 250’s average annual return rose to around 8.6%. On a 12-month view, it delivered roughly a total return of 10.6%. This may surprise some given ongoing weakness in the UK economy. Since about half of the index’s earnings come from within the UK, domestic conditions have a meaningful impact.
What’s driving the higher returns? One key factor is improved political stability in Britain in more recent periods. Between 2015 and 2022, Brexit and pandemic-related disruptions dominated, ushering in policy volatility and affecting appetite for domestic shares.
Another influence is broader demand for European equities. A more volatile U.S. political scene has nudged global investors toward diversification into overseas markets. UK and mainland European companies have also become attractive due to relatively attractive valuations.
Can this momentum continue?
If the FTSE 250 maintains its recent outperformance, many would say yes, there’s still potential for meaningful wealth creation. A 12-month return of about 10.6% implies that a monthly £500 investment in a low-cost tracker could, in theory, accumulate to around £1.4 million over 30 years. However, extrapolating short-term gains into long-term profits is inherently risky.
A more realistic approach emphasizes long-term averages rather than rapid, one-year bursts. Patient investing tends to yield a clearer picture of what’s achievable over decades.
Economic and political headwinds in the UK could temper future gains. Although stability has improved recently, the political climate remains unsettled, and the economy faces challenges such as labour shortages, productivity declines, trade frictions, and high public debt. These factors can influence corporate earnings over the long run.
A smarter way to pursue wealth
The FTSE 250 certainly includes standout companies, but buying individual shares can be a more effective way to pursue high returns than simply riding a market-cap-weighted index. Personal experience supports this approach, with examples like mid-tier names such as Greggs and Primary Health Properties forming the core of some portfolios.
AJ Bell (LSE: AJB) stands out as another compelling option within the FTSE 250 space. The financial services group has delivered impressive results well before its larger peers, posting an average annual return of about 13.3% since its London listing in late 2018. The sector is intensely competitive, yet AJ Bell has demonstrated resilience and growth.
Recent trading highlights reinforce this potential: customer numbers rose by about 19% in Q3 to roughly 644,000, while inflows lifted assets under management to new highs. This points to continued demand for comprehensive financial planning services.
If you’re seeking a high-conviction FTSE 250 idea today, AJ Bell earns a place on the short list alongside other mid-cap opportunities. That said, a diversified approach—covering a mix of well-chosen mid-caps and selective larger incumbents—tends to balance risk and reward over the long haul.

Important risk notes
All investing involves risk. Stock prices and dividends can fall as well as rise, and past performance is no guarantee of future results. Do not invest money you cannot afford to lose, and consider speaking with a qualified financial adviser to tailor any strategy to your personal circumstances. FX and overseas investments may add to costs and risk, including exchange-rate fluctuations and additional regulatory protections.
