This is why we have cash ISAs but not the investment ones. The building society is a safer bet right now.
But cash is only ever going to generate around 5 - 7% pa (give or take). That's only a little bit above inflation (certainly not enough above the inflation rate for me) and certainly no way to generate long-term wealth if you've got a long-term outlook (and time).
I'm assuming ISA's are a form of superannuation - is that right??
Hmmm,
I'm struggling with your logic. 5% gain or ??% £12k loss. As one of my pensions is tied up with stocks and shares I'd rather have some cash investment as well. I'll only ever be rich if you buy me the winning lottery ticket for the next double rollover so I'd rather run a more Never good to have all your eggs in the same basket.
What I was getting at is that cash investments will be steadily upwards at, for example, 5% pa. So you have certainty of your return but the chances for out-performance are limited. Shares will be up and down but historically the trend is upwards at a higher rate. However, you will have volatility. If you have time (and a long-term outlook), then you're better off with the majority of your portfolio in growth investments (shares, property etc). Of course, that will depend on each individual persons risk profile.
Granted, you need something in cash, but personally I wouldn't have any more than 10-15% in it, but that's just me, and I've got 15 - 20 years before I retire so I have time to ride out the rough patches.
But everyone should also keep an eye on their investments and review them every year
