“Man on tv. You ll be under water. You ll be losing money in other other words. The dividend gain is not worth the principal loss whoa.
I can t the pain. That s when you want to be a buyer alex the world of investment advice is a crowded and noisy place the good news is you can turn down the shouting. And you also don t have to follow stock quotes. Minute by minute in order to be a smart investor in the next few videos.
We re going to lay out some rules for smart investing no we re not going to tell you how to get rich quick. But we will give you some good advice for getting richer slowly and steadily now let s start with investment rule. 1. Ignore the expert stock pickers what if i told you that a blindfolded monkey throwing darts at the financial pages could select a basket of stocks that would do just as well as one chosen by the experts.
That was the controversial claim made in 1973 by economist burton malkiel. In his book. A random walk down wall street years later one of his undergraduate students turned out to be journalist..
John stossel and stossel. He set out to test this claim now blindfolded dart throwing monkeys. They re not easy to come by and the lawyer s a little bit worried so stossel threw the darts himself. John my darts landed on 30 companies how would they do compared to the stocks.
Recommended by managed mutual funds oops better alex sure stossel got lucky on his throws. And he reaped high returns. But the lesson here turns out to be correct random picking does just as well as the professionals. Let s take a closer look most people invest in the stock market by buying.
A mutual fund. A portfolio of assets like stocks and bonds managed by professionals. There s thousands of mutual funds. Some of them are actively managed they have experts picking stocks and charging fees the other type of mutual fund is called a passive mutual fund passive funds don t try to pick winners.
Or avoid. Losers they simply invest in a big basket of stocks such as the s p 500. Now this chart shows the percent of mutual funds that were outperformed by the s p 500..
You can see that in most years the s p 500 beat a majority of the actively managed mutual funds okay so perhaps you re thinking i got it most mutual funds don t beat the market. But what if i invest in the ones that do beat the market. The problem with this strategy is that the funds that beat the market are different every year in other words past performance does not predict future performance. The funds that beat the market this year.
They probably got lucky and they re unlikely to beat the market next year in fact one study looked at the 25 best performing funds. How many of these funds were still top performers just. Two years later less than 4 and after five years. Only 1 of the initial top performers remained in the top quarter.
So funds. Which are great this year. They re probably not going to be so great in the future they probably just got lucky okay. What about those very very few funds that do beat.
The market over many years hasn t warren buffett for example. The world s most successful investor hasn t he shown that you can beat the market. Maybe..
There s no denying buffett s a very smart guy. He s made some very good choices. But it s actually harder to distinguish luck from skill than you might imagine let me explain imagine that we started with a thousand so called experts. Except all the experts do is flip a coin those who flip heads say the market is going to go up this year.
Those who flip tails. Say the market is going to go down this year at the end of the year 500 are going to be right purely by chance now suppose that those 500 then flip. The coin again and they make a new prediction at the end of the second year 250 of these so called experts. They ll have been right two years in a row again purely by chance now keep going with this logic at the end of 5 years just 32 of the original 1000.
They will have been right about the market 5 years in a row. Now these 32. They ll probably be labeled market geniuses. They ll show up on television.
Their services will be in high demand. Perhaps some of them will write books about how to predict the stock market and get rich quick. What the laws of probability tell us..
However is that out of the initial 1000 experts about 32 were going to predict the market. Correctly. No matter. What the market did so are some market geniuses.
Truly skillful sure. But it also helps to be lucky. And it s sometimes not obvious. Which is more important in recent years in fact buffett s investments haven t done all that well so lesson number one is ignore the people who shout stock tips at you man on tv dividends funded by debt and not excess free cash flow are just too risky to own from now on alex.
And definitely don t pay big bucks for professional money managers. But what if you have some information about what looks like a great investment can you beat. The market well we re going to cover that and the efficient market hypothesis in the next video narrator check out our practice questions to test your money skills next up tyler will show you how a tragic space shuttle explosion can teach us about investing click to learn more music ” ..

In this first video in our Personal Finance section of Macroeconomics — and also our new course on Money Skills — we ll begin to lay out some smart rules for investing.
Today, we ll tackle Rule 1 ignore the expert stock pickers.
What s the basis of that rule? Well, in his 1973 book, A Random Walk Down Wall Street, economist Burton Malkiel made a controversial claim. He claimed that a blindfolded monkey, throwing darts at the financial pages, could select a basket of stocks that would do just as well as a set chosen by the pros.
One of Malkiel s later students, the journalist John Stossel, set out to test that claim. Stossel did throw darts at the financial pages. The darts landed on 30 companies. Turns out, Malkiel did have it right the randomly-selected stocks did better than professionally-picked ones.
The point here is, random picking roughly gives you as good results, as trusting the pros. Consider in most years from 1963-2008, the Su0026P 500 Index outperformed most of the managed mutual funds. And in a different study, researchers took the top 25% best-performing funds. Two years later, less than 4% of the original set remained in the top quarter. Five years later? Only 1% stuck around.
Basically past performance doesn t guarantee future results. Chance often tends to win out.
To show you what we mean, take a hypothetical set of 1000 experts making market predictions. Let those predictions be based on a coin toss. Experts who land heads will say the market will surge this year. Those who land tails say the opposite. At the end of the experiment s first year, 500 of the 1000 experts will have been right, solely by chance. Now, say the remaining 500 toss again. At the end of the second year, 250 experts will have been right, again by chance. Continue with this logic, and by the end of the fifth year, roughly 32 of the 1000 will have been right, five years running.
Perhaps these 32 will be hailed as geniuses, but remember, they only came about through a coin toss.
So, what s to conclude from this? Two things.
First, luck and chance matter. In some cases, it can be hard to differentiate luck from skill, as proven by the genius 32. Second, no need to spend big bucks on a money manager. After all, the studies prove that random picking often works just as well as professional management.
That said, what if you did have market information? What if you knew something about certain stocks, that made you think they d do well? Could you beat the market then? That s what we ll answer in our next video, when we tackle the efficient market hypothesis. Stay tuned!
