S&P 500 is hiccup. How investors should think about long -term returns.


However, there are concerns for those who know where to see, though. This year, the S&P 500 similar weight index is doing better than the regular index, dominating the tech behemoths. Is this a change in leadership? Defense sectors are rally. Healthcare, one of the worst artists of last year, is the best of this year. According to the BOFA Securities, the price stocks led to the 3.9 percentage points in February by 3.9 per cent, which is one of the top 5% for relative price returns. Meanwhile, shares in Europe and China are performing better than the US this year.

All this will release the indexes who are torn to fidel with their funds. Three UK professors have released a report that does not directly address the subject, but provides a clue of how investors should think about long -term returns. Paul Marsh and Mike Stonton at London Business School, and Elroy Dimson at Cambridge University compiled evidence on stock, bonds, bills, currencies and consumer prices and consumer prices and time periods in countries, including Wall Street not usually included in their glossy brochure.

The three presented their findings in a book near the turn of the Millennium, which is called the Triumph of the Optimists: 101 Year of the Global Investment Return, and since then offered annual updates, including the latest, 125 years data sponsored by Swiss bank UBS. Yes, I have read it, and no, I am not allowed to send you a copy, dear reader, as much as you are one of my favorite. But here are some observation that stand outside:

America has moved from extraordinary to extraordinary-aer. In 2000, the US was the best performing stock market of the former century, which was swelling from 14% to 49% of the world market. This is probably uncertain, with the two world warfast destruction in Europe and Japan, given its economic dominance and relative insulation. More surprising is how American dominance continued only, but developed, last year reached 64% of the world’s stock market price and 73% of developed markets.

Major markets do not have to lose their place to slip into underperformance. It is all necessary that good news is fully reflected in stock prices. But there are also Stark lead changes. The UK is 3% of the world stock markets, below a leading 24% in 1900. And this is not the most extreme example….

Gang Ho is not a commercial comedy. This is an investment horror prequel. Yes, I am talking about the 1986 film starring Michael Keaton. A Tokyo Auto manufacturer attempts to improve efficiency at a Pennsylvania plant. Given 33% positive ratings on cheerful ensues, or not, rottentomatoes.com. The plot reflected the Angest Americans felt at the time of ending their corporate dominance for Japan, which increased by 40% of the world stock market by 1989, vs. America at 29%. It turns out that only a huge property was bubble. Japan is below 6%today. Buy time? Maybe, but …

International diversification has worked. Except Americans. Putting money abroad was not one thing for most American investors unless a 1974 paper on the subject argued that doing so could be half the risk. Money was soon cheated, then swept away, then there was a flood in international funds. Investors in most countries get promised benefits. But for risky returns, American investors would have better to stay home. It is true whether they started at the time of that paper 50 years ago, or in 1980, 1990 or 2000. The US stock market has performed better, and non-US markets have demonstrated high volatility.

This is in a strange position of the theoretical support for an American eye -sight foreign shares, which has not been proved in the real world results. “Even for an American investor, it makes sense to diversify internationally,” says co-writer Marsh. “But this is not guaranteed.”

Bond smell. But you probably need them. The average real, or subsequent, returning to government bonds since 1900 was only 0.9% per year. And they are not as safe as you can. Return volatility for bonds has been less than shares, and shares have seen worse accidents, but Bond has also experienced more time. Investors who buy stock at peak before the Great Depression require more than 15 years to return to their early points, adjusted for inflation. But those who bought bonds at the peak of their 1940s required more than 50 years.

The real reason for buying bonds is that there are less relations between him and shares. In other words, buy some bonds-the ways will probably smell for a long time, but you will be happy during the rough ride for stock.

Stocks are great. Not just most of them. US stocks made an annual return of 9.7% in the last century and 6.6% in a quarter, or after inflation. It was enough to change a dollar in $ 2,911 to buy a dollar. Even if you buy stock everywhere, but America, you have made an annual 4.3% and changed a dollar to $ 194. A epic is not bad for missile. In fact, the stock was the best performing asset for all 21 countries with a continuous 125 -year investment history.

But most individual stocks are not great. Or good. Professors pointed to a 2018 study, showing that 57% of US shares had life returns that were worse than the Treasury Bill. The net profit for the US stock market in the last century is explained by only 4% shares. This is the real reason for keeping a large basket of shares like an index fund. This is not to dilute the loss from your losers. Most of them will be losers. To illuminate the winners, it is to widen the net significantly. If you own an S&P500 fund, you are growing rapidly on Nvidia since 2001. Congratulations on your foresight.

The US stock market looks focused. Or maybe not. Three companies recently made 19% of the market. Concentration is the highest in 92 years. Give something, or is it? The market was more concentrated in 1900 – it was 63% railroad. Somehow shares have done well since then the railroads are now less than 1%. And have you seen the concentration elsewhere? In France, three stocks are 23%market, Germany 36%, Korea 40%and Taiwan 59%. Among the dozen the world’s largest markets, the US is less than a third-less concentrated behind Japan and India.

Returns seem stinger but still fine. US stocks have made a comeback in the last quarter to a real 4.9% in a year, 7% versus one year as compared to the former century. Professors predict life returns by generations, and no one matches baby boomers. The generation can expect a real 3.9% in a year on a 60/40 portfolio of Z stock and bond – badly compared to other generations, which contains a point less than millennium, but rarely serious.
