I find this most striking in the shops: mostly I browse and don't buy. But once I've bought something, I'm likely to buy something else.
Investing can be like that too. For example, today I sold something that I probably shouldn't have sold - but I feel better now that I've done it and I can't wait to sell something else.
Regular readers will know that, when I sell, it is usually because I am cashing in a capital gain of 5-years-worth of income (in this case, dividends). I have this sell rule to stop me constantly agonising about whether a security value is going up or down - I hold it until it goes up that much, then sell it (but it's not always that straightforward). The sale gives me psychic relief - but it comes with a big potential downside, as I am 'selling winners', the supposed big investment 'no-no'.
Today's sale was AstraZeneca (LSE:AZN), which spiked up this morning, fell back then pushed up again. My sale realised a capital gain of 29% since I bought it in June 2011. The side-effects of this action may result in an upset stomach, when the price continues to shoot up - particularly after the annual figures and strategy update on 6th February, when the detail of the supposedly good news on the product pipeline will be revealed.
Now, if you were looking at AZN afresh, it would look quite attractive: yield over 4%, dividend cover 2.5, good news, etc. But let's not forget AZN froze the dividend just last year. so for an income investor, it means that they are to be treated with caution: perhaps they were being prudent or perhaps shareholder returns are not uppermost in the mind of the management?
In any case, I'm off those drugs for now.
