Its usually a bad idea for individuals to hold specific stocks.

Its never a bad idea for individuals to learn some basic code.

virincognito• 14 years ago

While I don't agree with your first point, it's certainly up do personal opinion. However, it's never a bad idea for people to understand how to invest and manage their money. From my understanding, that was what the author was talking about.

managing money != trading stocks

It's never a bad idea to learn how the stock market works and how political/social/economic/etc... changes affect stock prices.

yannickt6• 14 years ago

This reads like a request for a startup to teach people how to pick stocks. I am not sure this would be particularly useful, and I fear it could be dangerous. There is plenty of evidence that the average investor, instead of obsessing over the return on investment, would be better off putting their money in index funds and focusing on things that are in their control, like their savings rate, (tax-efficient) asset allocation, or minimizing investment fees. There is no shortage of accessible material on the subject.

Also:

"The old model of financial advisors, mutual fund managers and brokers is dying fast."

Is there any evidence to support this? I.e., are mutual fund managers making less money? And if formally trained investment professionals, as an aggregate, are not good at managing money, is it reasonable to think that individuals will do better with a code academy for stocks?

Do you have any evidence to supper your assertion that it is dangerous to train people in investing? I know its popular for people to throw up their hands and give up and claim that index funds are the way to go. I also know that many people who have done so, would prefer to think that they are doing the smart thing, and so they claim that this is the smart thing, despite the fact that it is really easy for anyone who thinks about it for a few minutes to beat those returns. Take an index- say the Dow Jones[1]. The companies in the index don't change very often at all. It would be very easy to buy a few shares of each company and simply hold them. You have the commission fees in the first year, but with discount brokers, that's pretty small, and then there would be no more fees. Meanwhile the people who gave up and just handed their money over to be "managed" in an index mutual fund are paying %1-%2 a year in fees. Spending an hour making a spreadsheet and you can keep your replica of the Dow Jones balanced by adjusting where you put new money in.

Why pay %2 of your investment, every year, to managers for something that would take you an hour to do once?

Over 10 years that's %20 of your investment, not even counting the effects of compounding.

Over 40 years that's %80 of your investment, not counting the effects of compounding which will be much more significant.

[1] IF you don't have the funds to buy the whole index, you can buy just the heaviest weighted ones. Further, when companies do leave or get added to the index, you can trade this when its announced, rather than have to wait like the index fund does, which means you get a better return because the index has to buy them after they've appreciated due to being announced as being added to the index.

Most good index funds have fees much less than 1%. Vanguard offers them for about a 0.15% fee.

yannickt6• 14 years ago

I never said that it is dangerous to teach people about investing. I am saying that investing is about a lot more than stock picking. Since passive investors beat active investors after costs [1], I think it is better for the average investor to focus on things that they can control to a large extent, like savings rate, fees, tax efficient asset allocation, diversification, investment horizon, etc.

Also, I do not advocate buying just any index fund, just those that are a good proxy for the market as a whole. The S&P 500 is much more representative of the US stock market than the Dow 30, and the Wilshire 5000 even more so. It is may be easy to replicate the Dow 30, it is much harder to replicate the S&P 500. And this assumes that one is only invested in US stocks, and is not diversified across other asset classes, such as international equities or emerging markets.

There are plenty of index funds that charge much less 1% in fees. Many charge 0.25% or lower. The following page has a spreadsheet that calculates the impact of fees on mutual fund investors:

http://wheredoesallmymoneygo.com/detailed-breakdown-of-the-r...

(Canadian, but the idea is the same for any stock market)

Using the spreadsheet, let's assume an initial contribution of 100K, an annual contribution of 5K, a 5% growth rate, no trailer commission and no advisor payout.

After 25 years, an investor who put the money in a fund charging an MER of 2% would have lost 33.72% to compounding costs versus a 0% fee portfolio.

An investor who put the money in a fund charging an MER of 0.25% would have lost 5.07% to compounding costs versus a 0% portfolio. I don't think that's a bad deal for the average investor at all.

The difficulty in this is that there's a much more cohesive perception of how you program javascript than there is on how you invest in stocks. In fact, for much of javascript there's little debate, yet for stocks there are large numbers of people who have been sold falsehoods and have become emotionally invested in believing them. Even the people who haven't fallen for snake oil are rather diverse in their investing strategies. For instance, my preferred vehicle, stock option spreads, are considered "too risky" by many people, and for others they just have trouble wrapping their heads around them.

So, I think the first thing that you'd need to do for such a startup, is to limit your audience to people who are independant thinkers, people who want to invest themselves and want to take control over their financial lives and haven't given up on the idea that they can be successful doing so.

This may have been obvious when you were writing the RFS, but I'm not sure what percentage of the market that is.. and if you want to address the whole market, you've got a lot of myths to deal with. (like the idea that the market is efficient, or that individuals can't pick stocks, or that mutual fund managers are better at managing money.)

Or, put another way, maybe the first module in such a system would be disproving these myths.

Like http://volcube.com ?

nirvana9• 14 years ago

That's interesting. It seems very focused on specifically training traders, and in options, for market makers, and the like. Something like that targeted at a broad audience might be really useful.

rayhano2• 14 years ago

I can make an intro to one of the founders for a chat...

andr• 14 years ago

There is a generally-accepted way to write software that works, even if there are alternative approaches.

With finance, there is not one generally proven way to make money. Once you get your feet wet in a financial market, there are no rules on how to make money or value stocks and other investment instruments. Experienced finance types lose money all the time. Someone that only completed an interactive learning game is bound to lose their savings.

nirvana9• 14 years ago

Think Or Swim, is an options trading platform, that has some very good software for analysis. You can get a free paper trading account from them. Probably some of the best training you can get would be to take that paper trading account, reduce the amount of cash (it starts with $1M) to the amount you really have to invest, and then start investing.

It lets you go back in time and buy or sell on specific dates in the past. This allows you to back test mechanical strategies. But for working with real time events, paper trading lets you make your trades with no knowledge of the future, see how you do as time goes on and have no money at risk.

Always a good idea if you're going to do anything with increased leverage (like shorting or options).

IceCreamYou2• 14 years ago

I sort of tried doing this for the PennApps Hackathon in January: http://unstock.me/

It turned into a silly little linear game. We realized that intelligent investment in the stock market requires setting up advanced models that require math beyond what most people can manage. If you're not working with such a model, you're probably losing money to the people who have one. There are some general concepts to learn about the stock market that don't have to do with math, but they're mostly pretty obvious and hard to make into a fun, game-like format.

IceCreamYou2• 14 years ago

Also, it's not just the math -- it's the data. Successful investors spend large amounts of time every day poring over financial reports to find companies whose stated value is different than their actual value. That's not something really teachable; you just have to want to sit there for hours doing it.

nirvana9• 14 years ago

Its really easy. You find companies with trustworthy management and sound businesses, look at their growth, find a reasonable discounted expected future growth, then calculate the net present value of discounted future growth. If the stock is trading for that amount, then you pass. If the stock is trading at a discount to that, then you buy.

Those who think the market is efficient are saying that there are no stocks like that... but if you look around, its not hard to find them.

When I was a buy and hold investor, I made %50-%100 returns each year spending about 5 hours a year in investigation (and most of that was just because I liked checking out possibilities. Most of it was fun. Once I'd found the keepers, it took me an hour each year - about 15 minutes each quarter- to update the numbers in the spreadsheet.)

veyron3• 14 years ago

The real problem is that the biggest lessons you have to learn (e.g. self control, ability to tolerate a small draw-down, discipline to act on winners and losers if your theory doesnt pan out) require a real-money test. You can learn modeling etc from a book, but the experiential knowledge requires you to play with cash.

yannickt6• 14 years ago

This is a great point. Most people I know largely overestimate their risk tolerance, and go from aggressive to conservative at the first hint of a market crash.

nirvana9• 14 years ago

Just because you are unable to be disciplined, does not mean you should project it onto everyone else. You may have jumped in and done stupid things- that's not uncommon- but deciding to give up afterwards, and then claiming that nobody else is capable of being rational-- is an error. You went so far as to say the idea of teaching people about investing was "dangerous".

That's quite a bit of overcompensation on your part!

corkill• 14 years ago

Except Codeacademy you are learning a skill which can be used to create.

Stock picking is essentially staking your money on something which you have no control over. I'm not against people learning about it. But yeah tons of better things to learn about, don't think it would take off. Seems like something to cover this would need to be more like an ongoing game and a lot less like code academy lessons.

Why do stock analysts, market experts etc even exist when they can hardly predicate things better than the average investor? Because there is a demand for them.
