I re-read Michael Lewis' Liar's Poker once every few years. In new reprints he's added a prologue where he says something along the lines of "I tried to write a book about the horrors of wall street and instead it became a recruiting tool for wall street" In a similar vein whenever something like this comes up I write something that says don't try and do this and inevitable I get 10+ emails from people saying "Ok I u…

If you get to 5, make sure you are judgement proof, and any loaned money is unsecured credit card money.

I honestly couldn't care less about credit card money losses, but I've seen too many people with assets(home, profitable website, really good job, nice cars) get reamed in bankruptcy court. Or, they lie about assets. Lie about assets, but make sure they never show up anywhere.

And just because you lied about your income on that cc form; in 99 percent of the time, it won't be mentioned in bankruptcy court. Credit card companies use your credit credit score to give you of money, and I believe they still redline(give more to certain individuals). Bankruptcy lawyers know most people lie on those cc applications. Yes, it's technically fraud, but try to prove it. They just don't. Nolo Press has a glaring error concerning income, fraud, and potential bankruptablity. It think newer editions corrected it?

If you get onto financial troubles, try to be proactive. Learn about what assets are legal to transfer. Learn about statue of limitations. Protect yourself from these bottom feeders.

(I don't want to debate anyone on the ethics of the cc industry. I just got a cc plea offering me a 29 percent offer, and if I could do it again, I would have ripped up that first cc card sent to me upon graduation, endorsed by my school.)

Isn't it the case that essentially no traders beat the performance of index funds long-term?

It isn't, there's fanous people like Warren Buffet of course, but I personally know of 3 individuals in investing forums who post all their trades and handily beat indexes over long periods.

Since you mentioned him: http://finance.yahoo.com/news/buffett-most-mportant-investme...

> Nearly a decade ago, Warren Buffett made a million-dollar bet: that by investing in a completely unmanaged, broad-market low-fee index fund, he could beat the gains earned by a high-powered hedge fund with a team of managers at the helm. His opponent was Protege Partners, LLC, a New York City hedge fund with $3.5 billion in assets under management.

[...]

> His simple Vanguard S&P 500 (VFINX) fund has delivered returns more than 40 points higher than those of the hedge fund. “I believe this is the most important investment lesson in the world,” he said.

It's just slot machines with a more respectable coat of paint.

Agreed! _A Random Walk Down Wall Street_ convinced me that asset allocation and saving regularly were the true ways to wealth in the stock market, especially if you consider $/hour of effort.

This is not how the math works, and it shows a common statistical fallacy. We cannot assume that the chance that a person loses money one year is uncorrelated with the chance that the same person loses money the next. Here is a simple model a mathematician might realistically use to model this. Given N traders, let P_1..P_N be iid Beta(α, β), and let the chance that trader n loses money during a year be Bernoulli(P_n…

I think he was just doing a play on words with the ambiguity and you went full math on him. >only 80% of them lose money over one year, but as time continues over multiple years, the percent [that loses some] money approaches 100%.

I'm probably going to continue going "full math" in the foreseeable future.

If we assume day trading is gambling, I wonder what the house odds look like contrasted against other forms of gambling (e.g. blackjack, poker, slots, horses, etc)?

I guess what I am asking is, if we take it for granted that it is gambling (and I am happy to do so) is it gambling with the best odds around?

Warren Buffett is not a day trader. To paraphrase, "My favourite holding period is forever."

He is a good data point to demonstrate that long term investors can beat the indices. Most don't, however, and it is my understanding that day trading is even worse. Just as there are professional poker players that can consistently make money, I'm sure there are some day traders that do very well, but it is not a skill that most people have.

This blog post did not answer it's own question because it's conditions were not day trading (over 3 trades in 12 months). That condition selects for people choosing individual stocks hoping for a moonshot, for which people tend to choose riskier stocks rather than stocks actually likely to make them money. So no wonder 80% lost money. On the other hand, notice that the 20% who do make money have a large power distribution curve.

A better way would have been to compare performance versus frequency of trading (I don't expect this to prove one way or another though). The fact is, there are many strategies one could take, and it's how well you execute them that counts.

Personally, I don't find daytrading riskier than holding stocks. By far my biggest losses come from holding the wrong stocks for a long period. It just seems riskier because you have to confront yourself with the possibility of loss each day, rather than hold "long term" and deny that you are wrong.

I now take the Doyle Brunson approach. The poker champion loved to pick up small pots and felt it was critical to do by aggressively playing small hands. That way, these little wins pay for the risk of playing bigger hands over time. I've had the same experience - my daytrading tends to be small money but it stems from work done for holding long term stocks. So why not put it to use?

But, to actually make good money daytrading is still really difficult. Commissions alone can make you have to be 55/45 correct, but there is also the steamroller affect where people tend to hold on to losses and double down further. So it's also about mastering yourself in addition to your market. Otherwise, there is not reason why you can't be better: you are putting in more work than others to make good decisions, and that's how you profit. Trouble is, when are you still outgunned informationally?

@chollida1 , you should write a book; help drive Michael Lewis' point home. In my last project for a brokerage system, I developed features for day traders. What was most surprising to me how much money the brokerage system generated for the bank regardless of the outcomes for the day traders.

With commissions per trade, brokerages love day traders. The more activity, the more money they make. They hate people that buy a stock with 3% dividend yield and don't touch it for 10 years.
