I have not invested the time and effort to become proficient at reading charts and how to apply the various different techniques to time the market. This website has been invaluable to me in growing my account through reading the market commentary and reading a number of people's market analysis (Uptrend, Coolhand, JTH, etc). However, I had a tough time taking my emotions out of my trades. I avoided the majority of 2008's losses, but what bothered me was that I also missed the majority of 2009's gains because I was too scared to get in. I was convinced that we were not done testing lows and as soon as I entered the market we'd go south again. Looking back on that, I figured there had to be a better way.
Spreadsheets are something that I love tinkering with, so that's what I did. Simply put, due to our IFT limits I decided that I didn't need a system that would get me in and out of the market every month - trying to hit the gains and avoid the losses. So what I ended up with is a modified Birchtree account. My system plays percentages - not market indicators. When we gain a certain amount, I take some off the table. Go down a certain amount, I buy back in. During a bull market there's a good chance that I'll be heavily invested for a year or more. To mitigate losses though (like 2008), when there's a steep drop and I've absorbed a certain percentage loss, I get 90% out (I never go 100%). My system shows better returns if I'm 100% out, but it's not significant, and I find it easier on my mind if I always have a little skin in the game. With a big loss like that, I've noticed turmoil at the bottom, so I don't go 100% in again until the markets have regained a certain amount. Just like bull markets, if we're in a bear market that triggers me to get out, I could be out for a year or more until the choppiness stops.
If anyone is interested in tracking my system, know this. When it's in the market, that's what it means. It doesn't matter which fund (C, S, or I), it just means be in one of those - it's more the percentage invested that matters. Right now I like the S fund, so that's what I invest in. When I take some out, it can go in the G or F fund. Personally I usually go to the G fund. I don't like losing money when in my mind it's supposed to be safe. Of course also know that I'm not a professional, you follow my system at your own risk, etc etc.
I tend to ramble a lot... Hope it made sense!
