And fairly safe if I stick to low risk shares?
High risks should equal high rewards, low risk normally returns low rewards.. it depends on your risk appetite.
This is how a rank them...
Under the mattress, please tell me where you live... lol
Saving accounts, zero risk but inflation will eat away at the value.
Premium bonds, low risk you may "win" enough to beat inflation you may not.
Other bonds, gilts or treasury, low risk.. do the maths in how much you expect to return and if you think inflantion will go up or down.
Market trackers, low to medium, it's alpha but it may not beat inflation in the short term.
employee share schemes, low to medium.. good chance to get discounted shares that may have a back out plan that only means you lose out to inflation or opportunity costs.
invidual company shares, medium to high... good luck doing research, big (large cap) companys don't tend to increase or drop that much, unless there's lots of hype or bad news, small companies can 100x but you can lose all your money next day.
Commodities, medium to super high... depends what you are buying frozen OJ or bitcoins or NFTs (if your stupid?! lol)
It's about spreading across as many assets as possible and allocating the correct percentage of your cash into the each one you want your finger in to the level of your risk appetite.
