If I was starting out now building my pension portfolio, these are two investment trusts I'd seriously consider. : When you’re approaching pension age, I think the best investments to go for are mature companies which are generating sacks of cash and paying out sustainable and rising dividends. Safe income is what I’d want, not the risk of unproven prospects. But when I talk to young people who are just starting out and have decades of investing ahead of them, they tend to think that’s a bit boring and want some excitement from growth opportunities.
