I have no intention of opening the eternal debate twixt speculation and investment as it normally stands. Rather, to take possibly the best definition of investment ever written, and contrast it with speculative practices. The initial quotes simply highlight from the blogosphere the most difficult aspect of speculation.
Today I had a couple of trades that ran well. A little while back I really want to milk these kind of trade for big profits. Since I am trading small, 100-200 share positions, I always want to capture $1-2 moves. I usually end up giving back all my gains by holding too long. A lot of times the stock would pull back and stop me out before it runs again. In many of my trades I would be up over $1 if I had taken profits, but end up with only 1/3 of that. Now I am not going to be that greedy.
I think taking profits is helping me psychologically, since I am taking in steady gains during the day. I am able to see things more clearly and take more trades.
The same problem.
On to the weekly recap of my trading. I ended the week profitable but only slightly. I missed my weekly goal of $1,000.00 in profits by about $800.00. That’s a big miss!!! The problem came from an old cliche about trading: Let your winners run. There were multiple instances of me being in a winning trade and exiting before there was any sign that the trade was slowing down. I’m not talking about instances where a trade will pause during the middle of a trend, trade sideways to slightly up and then resume in its current direction. No, I’m talking about taking a short trade and the stock does not print a single green bar but I am exiting anyway, only to see it move straight down another dollar. I even go back and watch the video and hear myself saying: ” I think I’m getting out now even though I believe it will keep going my way and has showed no signs of moving against me”. That’s messed up. So I know I have to figure out why I am doing this and either be able to fix it mentally or mechanically, i.e. trailing stops. Also i have found multiple instances of over trading during the middle part of the morning. I want to make money so I am attempting trades when the market has no real direction and just chops around. Got to fix that!! There were also two or three times when I would exit a trade before my stop was hit only to see the trade go my way very quickly. I would feel anxious about losing money on the trade, even though my stop loss was well within my average loss limit, and just bail so I would not have to feel the anxiety of having a possible loser. And then when the trade would start to go without me I would revenge trade and lose money. So instead of keeping the winner and making $400.00, I exit, jump in another stock and lose $160.00. Another problem to fix.
A “Mechanical” solution?
Taking the trades tomorrow will feel like I’m getting back on the same big ass bull that just bucked me, except now I’ve got my tailbone shattered, my chest gored, and hands rope-burned.
But what else can I do? If I do not take the trades, then I may miss a crucial turning point. Or not. They may just generate more losses. In fact, if all 5 trades stop out, they will erase all of my gains from the last 2 months.
The point is, one doesn’t trade a system if he can see the future, or if he can accurately predict market turns. One trades a system because it provides an edge that is assumed to be better than what can be offered from his mental faculties.
In other words, when one overrides a system, a variable is introduced which has typically not been tested. To make matters worse, this variable is more likely to introduce error and chaos, due to the fact that it is usually discretionary, a byproduct of one’s psychology, biases, etc. Remember, one would not be trading a system in the first place if he was programmed mentally to trade with an edge. What I have found is that intervention seems to capture the worse elements of the system, and magnify them.
What makes system trading hard for me is that it is very difficult to reject the urge to intervene. I’m not sure why I’m having a problem with it. It may be that I’m relatively new to the concept and just have not gotten used to being completely mechanical.
Let me now reproduce an older post [posted under expectancy]
Expectancy is your profit percentage per win multiplied by your win rate minus your loss percentage per loss multiplied by your loss rate. I will use an example of Expectancy from Dr. Van K. Tharp’s Book: Trade your way to Financial Freedom:
Expectancy = (Probability of Win * Average Win) – (Probability of Loss * Average Loss) Expectancy = (PW*AW) less (PL*AL)
PW is the probability of winning and PL is the probability of losing.
AW is the average gain (win) and AL is the average loss
So let’s do an example using another basic approach (assume $12,500 per position, a $100,000 portfolio using 1% equity risk):
If my trades are successful 40% of the time and I realize an average profit of 20% but I lose an average of 5%, my expectancy is $625 per trade.
(0.4 * $2,500) – (0.6 * $625) = $1,000-$375 = $625
I lose 60% of the time yet I show a profit of $625 per trade. If I have a system that produces 65 trades per year, I would realize an annual gain of $40,625 (hypothetical scenario). A 40% gain on the original $100,000 (minus all commissions, fees, taxes and compounding).
Let’s look at the calculation one more time using only percentages:
PW: 40%
AW: 20%
PL: 60%
AL: 5%
(40% * 20%) – (60% * 5%) = 5.00%
What this tells me is that I have a positive expectancy of 5% or $625 per trade from the original $12,500. It doesn’t mean that I will make $625 on every single trade but my system will average a profit of $625 per trade over the course of a year with a combination of winners and losers. I can always make more trades or fewer trades in a year so my total profit will be adjusted accordingly.
I also wish to add to this post with “the” definition of investment, made almost 100yrs ago, quite remarkable that in the intervening years, rather than being surplanted by an improved definition, it has simply been proven through the passage of time;
“An investment operation is one which, upon thorough analysis, promises safety of principal and a satisfactory return. Operations not meeting these requirements are speculative.”
There are some similarities twixt the rules of “expectancy” and the definition of investment. Are the similarities enough to qualify the rules of expectancy, rigorously applied, the sobriquet of an investment operation?
