Perhaps its human nature, impatience, a lack of discipline, or a combination of all three, but our apparent willingness to seek short cuts probably accounts for the frequency with which savers and investors ask themselves whether, by doing A or B, or maybe investing in X or Y, they can bank a quick profit. Frankly, unless theyre incredibly lucky, the answer is a resounding no. James Dysons experience proves the point. While developing his eponymous vacuum cleaner, the inventor, industrialist and all-round good guy exhausted his savings and, incredibly, produced a staggering 5,126 prototypes before creating the perfect vacuum. The temptation to take an occasional short cut must, at times, have been overwhelming, but Dyson persisted; today, hes worth an estimated £3 billion. Not surprisingly, almost all of our attempts to boost our bank accounts in double-quick time are undermined by an uncanny propensity to miscalculate, misjudge or misinterpret. Lets just say were prone to errors of judgement. This conclusion should not, however, prevent us from trying to tip the scales in our favour, but the most effective way in which investors can do this is by not losing money, or giving it away unnecessarily, in the first place. Indeed, there are a series of simple rules to which investors should adhere which will enable them to retain more of what is theirs. The first, and most obvious, is to reduce the impact taxation has on your savings. Im not advocating the establishment of some opaque offshore tax vehicle which deliberately evades tax, but something very simple and extremely tax efficient. Taking advantage of annual tax allowances makes enormous sense, which explains why people pour money into ISAs every year. Cash ISAs are understandably popular, although returns are modest, with fixed interest accounts currently offering no better than 1.60% a year. Savers seeking to improve upon this might prefer the stocks and shares ISA, into which they may place up to £20,000 during the current tax year. Admittedly, not too many people have a spare £20,000 knocking around with which they can embark upon their ISA journey, but nowadays, its possible to open an ISA with just £1. It follows that getting the ISA ball rolling is one of the best saving-related habits you can have. Investing just £150 a month in a stocks and shares ISA, assuming a 5% annual compound return, would build to £10,200 in only five years, the gain on which (£1,200) would be completely tax-free. If ISAs are a good idea, so too is awareness. By this I mean it helps if you know what type of investor you are. Researchers have discovered that our investment choices are often influenced by factors that could be genetic or determined by our backgrounds. For instance, people who experienced hard times during their youth are likely to own fewer investments than those who were at the opposite end of the economic scale when growing up. In addition, psychologists at Harvard University found that sad people save less, while folks who are happy or angry are inclined to accept more risk than normal when making their investments. And lets not rule out wishful thinking. In other words, theres no point believing returns will suddenly soar simply because youve opened an ISA, but what type of return can you expect? Research by Barclays shows that annual stock market returns have averaged around 5% since the end of the nineteenth century, so its reasonable to assume a similar level of return over the longer term. Finally, theres enormous merit in embracing the get rich slowly mantra. While a lottery win or a handsome return from those Premium Bonds you received for your 21st birthday might solve burgeoning financial woes in an instant, the laws of probability almost certainly exclude such a likelihood. Instead, accept that, just as its easier to lose weight slowly, so its simpler to save more over the long term in an attempt to reach your saving goals. To conclude: yes, a one-off boost of several million would be perfectly acceptable (I do not subscribe to the view that all that money would make you unhappy), but consider this: you have a greater chance of being decapitated by a frisbee than winning the Euromillions jackpot. Worth bearing in mind when mulling over the benefits of opening an ISA THE WEEK IN NUMBERS 12 years The annual measure of train punctuality has fallen to its worst level in 12 years. In the 12-month period to mid-August 2018, a total of 14pc of trains were late. 112 At 112 years old, Britains most elderly lady is Mrs Grace Jones. Mrs Jones attributes her longevity to a glass of Famous Grouse whisky every night. Whisky is very good for you, explains Mrs Jones. I never miss my nightcap. Presumably the marketing department at FG have already despatched Mrs Jones a few crates of their very best stuff. £ 33,127 According to the Halifax, the average deposit required by first time house buyers has risen to £33,127, an increase of 71% in the last decade.
