Quote from MDCigan:
Couple of thoughts here because I think this is potentially a dangerous line of thinking because it has the potential to make one give up on the idea of trading options or the opportunities that exist.
I really see this as analogous to the line of thinking in equity world which says the market is perfectly efficient, you've got tons of professional analysts covering stocks, all FA and TA is bunk, so why bother trying to trade equities.
1. PhDs and their models. Frankly, I've never been impressed by this argument when applied to anything. IMHO, having a PhD doesn't imbue one with some sort of God-like quality that makes non-PhDs unable to compete. And all those ultra-sophisticated models are just that, models. There is no trader's intuition of just plain trading common sense or experience behind those models. I've got 4 letters as far as PhDs and their models. <b>**LTCM**.</b> Right there, you supposedly have some of the most brilliant PhDs period and some of the best constructed models. What happened? They blew out pure and simple. Bottom line, IMHO, having a PhD and a model doesn't mean you have the trading intuition and experience that is just as important for long-term profitability.
2. Regarding Upstairs Traders. Maverick, GA (other former MMs), correct me if I am wrong, but my understanding is the upstairs guys are playing an <i>entirely different game</i> then what we are talking about. My understanding is they are trying to exploit ultra short-term price discrepancies, looking to do reversals, conversions, any kind of short-term riskless arbitrage, and/or make profits from very short-term order flow effects. What we are discussing here are position trades that are longer term in nature, at least compared to what they are doing, and that rely on correctly forecasting future price, future volatility, or profiting from the passage of time, nothing related to any kind of pure arbitrage. I don't see how anything they do even remotely impacts the sort of trading opportunities we are talking about.
I do concur with everything you just said. It is a very different game. And we could expand on the list of names beyond LTCM and Susquehanna. Ever heard of BAM? Beacon Asset Management. THese guys had the smartest quants in the world doing mortgage back securities arbitrage and did very well for ten years until last fall when they lost 700 million in one month!!!!!!!. After making 15% to 20% for 10 years they lost 50% in one single month and to make matters worse they lied to their investors saying they were only down about 20%. Needless to say, they shut down and have massive lawsuits filed against them. Real smart guys. Ever heard of D.E. Shaw? He is a former market wizard. Runs a huge and highly secretive quant shop in NY. He did well for many years but then damn near blew out the firm in 98 when bond losses got out of control. The list goes on and on.
What I have noticed is this. These guys have the technical expertise to exploit and extract nickels out of the market on an intra-day basis not so much because of how smart they are but the technology they have and their ability to execute. But whenever they try to speculate on longer time horizons they get killed. Why? Because math doesn't mean f*cking squat over time. In fact, one could argue that you could graph math prowess over time with a p&l line and you would discover that as you go out in time, the element of luck and chance increases while the mathematical certainty decreases. So as all these guys take on bigger and bigger positions that have longer duration reducing the mathematical edge they have and exposing themselves to luck and chance at a higher frequency. This is why there is a pattern that when they quant guys start out small and make money and then they have more money to put into the mkt so they increase the duration of their trades and then blow up. Very predictable pattern.
So I think what most guys do on this forum has no relevance to these quant guys and thank god, with their longevity record, I'm not sure I would want to have anything in common with any of them. The bottom line is this, with options, you need to have a very good feel for what you are doing. You need to manage your risk and create positions that will allow you to profit under the most scenarios. This is why I believe and continue to believe that options are better then stocks and futures. Because you can place so many bets in so many different directions that any number of things can happen to make you money. The key is controlling your risk.
I think if there is a so-called edge that upstairs guys have its called connections. For example you give me a call 10 minutes before the close telling me that your top analyst is going to downgrade stock XYZ to a sell and then we load up on puts. Don't think that happens. Ha. I use to take the calls! That's the edge my friend. Inside info will make you 100 times as much money as any group of quants creating computer models that just took a nickel out of the market. Of course like anything else you have to weigh the legality of it. Some of the guys will never see the fortunes they made because they will be getting to know bubba who sleeps on the bunk above them and likes to take long walks and likes to cuddle after sex. LOL.
Therefore, I think by playing the game straight up, we don't run that risk. There is more then enough opportunity out there for us to put on positions. There must be over 10,000 equities and with retail options trading breaking new records every day, the little investor is going after options with a vengeance. Add the emergence of more electronic exchanges and you have yourself a recipe for a beautiful money making stew.
It's funny, I have met many of these so-called quants and they don't even know what a support and resistance level is. They have no idea what buying the rumor and selling the news means. They use to ask me why stock XYZ was down 5 pts after hours when they just blew out their earnings report. I use to laugh and then think, wait a minute, am I smarter then these guys?
If you really want to get some good insight into the validity of quants and the true return on their money they really get, read Taleb's "Fooled By Randomness". He has a great chapter that says, "If your So Smart, Why Aren't You Rich?" He completely debunks the use of quants in finance and trading, and he is a Quant!!!!
Well, that is my latest rant. I should get credit for multiple postings when my posts are this long! I'll never catch Metoox at this rate. LOL.
