Kevin, you mentioned above couple times. Can you say a little more on this subject. Your opinion is valuable.
For long time I sticked to this mantra and in consequence I didn't trade large just because mixture of risk and my style of trading was to dangerous for my liking. Now I try leverage, very conservatively, and just looking around while stepping in this area. Do you base your stance on some studies, on some facts maybe (plenty of them) or is it mostly personal opinion?
Marcas,
My opinion is based on my personal experience. I have been through margin calls before and they weren't pleasant experiences. Brokers can increase their margin requirements overnight without explanations. While those were unpleasant experiences for me, I have known personal friends who got wiped out completely because of their over-leveraged positions. I have been through several market meltdowns - 1997 Asian financial crisis, 2000 dot com bust, 2008 global financial crisis. In every one of these, I knew people who got wiped out. These are very intelligent and once-successful people. Couple of them went from positive tens of millions to negative. All due to over leveraging. Those are life lessons for me and the reason why I made a promise to myself never ever to get caught in that mistake. If the trade off is sub-optimal returns, then let it be.
If you have read the story about LTCM, again that collapse was due to over leveraging as well. More importantly, before they got hit, people in LTCM were viewed as geniuses, and their strategies were considered super safe. As yield became smaller and smaller, they convinced themselves that they had a low risk strategy and hence they increased leverage. Of course, as the saying goes... the rest is history.
To me, a highly leveraged strategy is like playing Russian roulette with a gun with 1000 chambers. Although the chances of getting hit is extremely small, but if the cost of getting hit is death, then my decision is not to play the game. The end-result is less profit but I'm guaranteed to not have to deal with a consequence that I'm not prepared to accept. Therefore, I made it a red line. I try not to even analyze the decision too much because the more I analyze, the more I could rationalize away the risk and convince myself perhaps this time it's different.
So that's very much a personal decision. Many people will disagree and that's perfectly fine. But having said that, what I'm talking about is highly over-leveraging, meaning leveraging 100% to even 1000% of your capital. Those are the cases that will get us into trouble. Occasionally, if we need to slightly go over our capital temporarily, personally I think those kind of leverage is fine.
