So, the problem is so many people think they can find an edge by NOT buying and holding. But, as has been proven time and time again, it is EXTREMELY hard to beat buy and hold over any meaningful time period (several years plus).
So, why fight it? Why not just incorporate buy and hold?
So, here is what you do. You put 100% of your capital into SPY. In a margin account.
You've done your back testing, you know some scenarios where you should go in BIGGER or go in LESS. Like, for example, in some other thread someone said on days when the SP500 has had 3 down days, if you buy and hold for 3 days, you 3 days you hold will be, on average, far more positive than your average day.
But you are NOT going to NOT buy and hold, because the number of times such a scenario comes up are relatively few. You just could not compete with buy and hold.
So, again, you are going to be 100% invested in buy and hold. HOWEVER, on those days where you've done your back testing and you have statistical proof that being long or short those days were significantly outperform, you will go long or short ON MARGIN. So on those special days you might instead be 105% invested. Or 110% invested. Or 90% invested. You can adjust for your risk tolerance.
Now, if your back testing is even half arsed, and remains relevant for future time periods, you know you are going to profit on those trades. So you guesstimate what you anticipate profiting on those trades. Of that guesstimated profit, you buy some tail protection. Maybe like SPY puts 30% out of the money or something. Something so that, when 2008 comes around again, you are well protected. And those you are buying on margin, to be funded by the profits you make from your margin special trades. All the time remaining 100% invested (subject to less on those special days), thus buy and hold.
So what do you have? You have a portfolio that on average has all the benefits of a pure buy and hold strategy, but you have some marvelous tail protection. On average your portfolio will perform at least as good as a buy and hold, but with SIGNIFICANTLY less drawdown.
And that, my friends, is creating edge and beating the market...
