Keeping scoreHere's a simple question. How important is the purchase price of my investments?
Here's a simple answer. Not at all.
For a long-term investor (which I am, or would like to be), there can't be any debate about this. Once I have put down my money, the deed is done. If I own 1000 shares in company XYZ, it doesn't matter if I paid 1p or £1 for them. Any decision to sell the shares, or buy more, must be purely rational based on the current share price, and not take any account of my purchase price.
The only reason to keep track of the purchase price (besides tax reasons) is to keep score. Interesting, perhaps. But not relevant to any future decisions.
I need to be on my guard here. My instincts are to place huge weight on purchase price:
- Not wanting to sell at a loss. This would be tantamount to admitting a mistake, which is hard to do.
- An urge to average down when share prices fall. If I'm 50% down I want to double my investment so that I'm only 17% down.
- Not wanting to increase my holding at a higher price than my initial purchase. If I'm 50% up I don't want to double my investment and end up only 25% up.
Now this doesn't mean that it is irrational to buy more shares when the price falls - as long as I'm doing it for the right reasons, i.e. because I have spare cash and want to increase my holding because the share is good value.
Equally if I buy shares at a 50% discount to true value, and they then shoot up 80% without any change to the real value, then there is no point buying at only a 10% discount.
Timing
An attempt to rough out my investment strategy for the next 2 years.
H1 2008
I would like to build a reasonably diversified portfolio. But I want to buy shares cheaply. I think the next few years will give me the opportunity to do this. I need to be on my guard for opportunities as they arise, but I need to be patient as well.
So far I have a large number of bank shares, bought too soon. Patience would have paid off here.
I have a moderate number of building shares, bought too soon. Patience was definitely warranted here.
I have a large number of chemicals shares. No particular timing problems.
I have a large number of diverse IT shares. No particular timing problems.
I have a small number of pub shares. These are hard to call - I think they will probably go lower. I have probably bought too soon, but will be patient before buying more.
I have various ETFs. No particular timing problems.
H2 2008
I have some money left to invest. I will get some more in a month or two. I will get more in November, and a lot more in January.
For the moment I think my focus should be on increasing my ETF investments. I think a 50/50 split between ETFs and my own choice of shares is a reasonable split. I'm currently at 28/72. I will try to focus on that for the rest of the year.
H1 2009
I will look at bank shares again in the light of a full year's results. I believe RBS's earnings will remain robust, and that banking shares may be amongst the first to benefit from a recovery.
If a general bear market has been in force, I will look at defensive shares such as GSK, DGE, in the hope of picking them up on the cheap.
I will look out for any heavily oversold quality shares in sensitive sectors such as housebuilders, big-ticket retailers, etc..
H2 2009
In the hopes of recovery I will look at builders, retailers, office owners and others that have suffered in the downturn, trying to pick up a mix of quality companies well placed for a recovery.
H1 2010
Assuming a recovery is taking hold, I will look at companies that will benefit from expaning corporate investment: software services, building supplies, etc...
