Investing in stocks because of patterns seen on a chart has made people billionaires, too.
Nope, not really. There's a reason that there isn't a famous technical analyst billionaire like there's a famous value investor like Buffett: because technical analyst billionaires don't exist. They get paid low six figure salaries to make fools of themselves on CNBC, or they get paid big bucks if they're good enough salesman to sell picks on a website or convince investors to give them money to invest, for which they charge a huge fee (to deliver sub-par results, of course).
That's why technical analysis is alive and well today. He11, there are probably lots of people who have read a charlatan like Kiyosaki and have become millionaires buying and selling real estate and shunning the stock market like he espouses. However, just because "numerous" people have made money using any particular method (pick your favorite) doesn't automatically validate a particular method nor does it prove that one is destined to make market beating returns in the future.
You should read the same article I mentioned to RedDog earlier: "The Superinvestors of Graham-and-Doddsville." Buffett specifically addresses your argument here. The short version of the article is that if you had 200k investors all studied, and 250 of them beat the market over 30 years, then that wouldn't be statistically significant. It could easily be an aberration with those kinds of numbers. But if you found that all 250 (or even just a third of them) all went to the exactly same school and invested using the exact same methods, then suddenly it becomes very statistically significant. To the point that it's no longer possible that it's just chance. And that's exactly the case with true value investing. Buffett goes through a big list of them in the aforementioned article and shows their results. Give it a read.
According to Wikipedia (the source of all truth), there are about 14,000 mutual funds in the US today. Out of those 14,000, there are probably 1,000s of mutual funds that undertake a fundamental analysis of the companies they purchase. They DO have the time to make accurate analyses of just about any company they want. These funds hire the best and the brightest the financial services industry have to offer. They have a huge amount of computing power at their fingertips. They hire highly educated guys/gals with lots of initials after their name who work 80+ hour weeks.....yet.......
When you look at the financial performance of mutual funds (for example), especially over long periods of time, they underperform their benchmarks. Depending upon who you're reading, over a 10 year period, 70%-80% of mutual funds underperform their stated benchmarks, not even taking into consideration survivorship bias. Look back 20 years and the record is even worse.
So my question is this....if what you say is true. If all one has to do is undertake a proper fundamental analysis of company stock before making a purchase, why do mutual fund managers continually underperform? Even the ones that use fundamental analysis? Even the ones that make concentrated bets and few trades using fundamental analysis? Even the ones that make lots of bets and make lots of trades using fundamental analysis?
We're not just talking fundamental analysis here. We're talking a very specific subset of fundamental analysis: deep value investing in the vein of Graham, Dodd, Buffett, Munger, Fisher, etc. The kind of investors who don't pull the trigger on a purchase unless they see a discount to intrinsic value of 30+%.
But there's also another reason that you don't see great performance from mutual funds, even with the best and brightest: because nobody is willing to pay a management fee to a money manager who goes months between making trades. Managers feel the need to constantly be showing work. They need to be buying and selling something, otherwise they worry that investors will feel they aren't doing their job and take their money elsewhere. That's why you see even funds that Morningstar would classify as "value" funds with turnover rates over 50%. Are these really value funds? Absolutely not. They're only value funds by comparison to the growth funds, which sometimes have turnover rates of over 100%. Turnover kills profits, and no true value stock matures to its intrinsic value in less than a year.
