Investec Group (LSE: INVP) is emerging as one of the more compelling dividend stories on the FTSE 100 for ISA investors seeking tax-efficient income growth.
A Stocks and Shares ISA remains one of the most effective vehicles for building long-term wealth, given its exemption from both income and capital gains tax.
Unlike private pensions, ISA holders can make withdrawals at any time, adding a layer of flexibility that appeals to a broad range of investors.
The rise in the FTSE 100 over the past year has pushed down dividend yields on many stocks, as returns fall when share prices climb higher.
Investec, the international bank and wealth manager, stands out with a current dividend yield of 6.3%, more than double the FTSE 100’s 3% average.
Analysts expect that yield to climb further, reaching 8.2% by the end of 2028, making Investec a notable prospect for income-focused investors.
A £20,000 investment, the maximum annual tax-free ISA allowance, placed into Investec could generate £25,284 in dividends over 10 years, assuming an average 8.2% yield with dividends reinvested.
Extending that timeframe to 30 years, and applying the same compounding assumptions, that figure rises dramatically to £212,146 in accumulated dividends.
Including the original £20,000 stake, the total holding would be worth £232,146, generating a projected yearly income of £19,036 at that point.
Sustaining those payouts over the long term depends heavily on the company’s ability to grow profits consistently across its banking and wealth management operations.
Analysts forecast Investec’s profits will grow at an average rate of 13.1% per year through to the end of 2028, a notably strong projection for a financial sector firm.
Return on equity, a key profitability metric for banks, is projected to reach 15% by that same point, indicating robust underlying financial health.
Risks remain, including potential tightening of financial sector regulation that could increase compliance costs and restrict parts of its operations.
A prolonged period of lower interest rates could also squeeze margins across its lending business, adding uncertainty to the longer-term income outlook.
Despite a share price rise following its promotion to the leading index on 22 June, Investec still appears undervalued relative to its peer group on several metrics.
Its price-to-earnings ratio of 7.9 sits at the bottom of its competitor group, which averages 12, with peers including St James’s Place at 10.8, Aberdeen at 11.5, ICG at 11.6, and Man at 14.2.
Investec’s price-to-sales ratio of 2.4 and price-to-book ratio of 0.9 both sit below peer group averages of 2.9 and 2.4 respectively, reinforcing the undervaluation case.
These valuation gaps suggest that if profits grow as expected, the market may re-rate Investec’s shares closer to sector norms, offering potential capital gains alongside dividend income.
Simon Watkins, who owns shares in Aberdeen and Man, noted that existing holdings in the same sector preclude him from adding Investec without unsettling his portfolio’s overall risk and reward balance.
For investors without that constraint, Investec’s combination of strong forecast profit growth, a rising dividend trajectory, and apparent undervaluation makes it a stock worth serious consideration.
