Compared to many people here who buy index funds and rebalance, or people who buy a balanced active fund like Wellesley or Wellington, I guess I can call myself an active investor.
I did not even know about the Bogleheads before I surfed this forum. I did not even know that my style was called slice-and-dice, so I could claim that I independently discovered this method.
As I started to experiment with buying individual stocks in the late 90s after rolling out my megacorp 401k after leaving it, and read different books on investment strategies, I observed that there were always hot and cold sectors. And I thought to myself that if one just rebalanced between these sectors, I could make a bit more money.
Of course, it would not help if one kept buying horse buggy sectors in the early 20th century, so it is not that simple. So, my performance has been a bit mixed. Some years I did well and beat the S&P500, some years not so. I take full responsibility for my action, but am reluctant to talk about it. It's simply an individual choice.
So, does the above make me an active investor? I do not do day trades, and can claim that my portfolio turnover is even lower than Wellesley, which is lower than most active funds. Of course, there have been times when I thought to myself that I would do a lot better if I did not hold on to my winners that long and if I traded more.
