Shares have taken a bit of a pounding. Unusual for the end of October. Still these are unusual times. The temperature outside our house is not bonfire weather at all more like lunching on the lawn weather.

Shares are down because profit takers are at large, rather than big economic bad news. There isnt a lot of that. We all know employment figures are high, but the rate of increase is getting smaller. And Tescos announced that they are taking an another 1000 workers.

Tesco (LSE: TSCO.L - news) is a difficult choice should we buy shares in the giant or not? One reason I have shares in them is that they are so blinking huge that one could never imagine their getting into trouble. But then, didnt I think exactly the same about the Royal Bank of Scotland (LSE: RBS.L - news) and Lloyds TSB? I rather think I did.

Even so, Tesco wont deal in strange financial waters like the banks did. They will make profits on the amount of food they sell. Oh yes, and all the other stuff they do which seems like everything. Insurance, lending and loads of financial stuff as well as selling no food.

I also buy Tesco grub because they do a very good delivery service, which no other supermarket does in my area. Not to the same extent, anyway. Being a very busy chap ok, a lazy one I cant afford to spend half a day driving to the supermarket and trying to find my way round ever changing displays. One in every seven or eight pounds is spent by Britains with Tesco. Hows that for market saturation?

The trouble with my Tesco shares, however, is that they dont race ahead. They are probably too big to be taken over, so the share price can only go up with profits. And these need to grow year on year. Will the time come when Tesco grows so big, it can only shrink. Possibly. And thats why I may sell a few Tesco shares soon but not perhaps for a week or two. The Santa effect may send the price rising a bit more yet. Rock on.
