When it comes to the long -term investment in stock and ISA participation, I have long admired the idea of ​​iron strategy that invests in two parties.

At one end, the investor can accumulate in defense companies with stable cash flows and profit distributions that quietly put a mark on the background. On the other hand, high-volatile growth, risk-fraught shares are added, but they are able to freely charging ISA if they delivered them.

This division is what makes the approach very attractive. In theory, the defensive hemisphere provides the sober wallet when the markets fluctuate, while half of the growth gives an opportunity for huge returns. The trick, of course, is to find the right mix.

For investors who are keen to implement this strategy, here is one share of each camp to look at.

Unilever: The defensive anchor

Few stock embodies reliability like Unilever (LSE: ULVR). The consumer goods giant pays profits for more than 20 years, and with a return of 3.3 %, it is a constant motivation for those looking for an income.

More importantly, the nature of its products – daily elements such as food, soap and cleaning products – means that the demand does not fall as a cliff during the recession. This makes it shares that many investors may think on the ISA defensive aspect.

Now, it is true that the stock price was not completely exciting. Over the past five years, only 80.7 % have risen. Compare this to the names of the contestant technology and it appears slow. But the work is very profitable, as it publishes a 28.8 % return (ROE), which talks about using effective capital.

The risks are still present. Inflation has pressed consumers to trade with cheaper alternatives, and this is the margins. In fact, debts now go beyond stocks, which do not sit comfortably for the company that is believed to be very safe.

However, with a global imprint and a variety of products, I think Unilever still represents a good share of stability within ISA.

Babcock International: aggressive play

On the growth side, Babakuk(Lse: Bab) was one of FTSE 250The brightest stories. The shares have increased by 355 % in the past five years, reflecting both strong implementation and market enthusiasm for defense contractors.

ROE is 49.75 % striking, while revenue increased by 10 % on an annual basis. The profits also jumped by almost 50 % – not something that is seen every day in a sector often dominated by slow and steady growth.

The UK recently obtained a defensive deal worth 13.5 billion pounds with Norway, which should help strengthen the sector. With geopolitical uncertainty, it does not disappear any time soon, the demand for these services may remain strong. In general, Babcock is the high growth type that the investor may think at the other side of the iron.

Of course, there are defects. Defense companies live and die due to government contracts, so political transformations can turn very quickly. Large-range projects also carry the risk of implementation-they can take delay or cost excesses a bite of profits.

Budget

Arrows and stocks do not need to be fully tilted towards safety, and not completely growing. The Barbell approach is both mixing, allowing reliable names such as Unilever to compensate for wild companies ’fluctuations such as Babcock.

For me, it is an elegant way to invest with balance. Although the risks should not be ignored, this mixture of brace and ambition is a frame worth considering any long -term ISA strategy.
