Gnasher epitomises all that is perfect about a naughty boy's dog - it was more than willing to take part in almost any kind of mayhem (with gusto), and in some cases pushed Dennis' admittedly limited boundary of self-control.
Perhaps we all have a mental investing Gnasher that we don't always keep under control.
Gnasher came to mind because I have just sold National Grid (LSE:NG). [If you haven't spotted it yet - an anagram of Gnasher is - NG Share.]
I have spend a couple of weeks sitting on my hands for a couple of weeks, biting my nails looking at the uneven rise of the share price (a rise for no apparent reason that I can identify). This Monday morning, the sun is shining NG is up again and I'm feeling reckless. My Gnasher brain takes over - "just sell it, yeah!"
As income shares go, NG has been a model. I bought it back in 2011 and since then it has oscillated in value but always paid a welcome 5%-plus dividend.
As regular readers will know, I have a weakness for grabbing a profit but I discipline myself by holding on until I have made a capital gain equivalent of 5 years' current income. I had to review my holding in April 2013 when they changed the dividend policy - but I held on. This time I held on a bit more, because of the continuing good yield and also the positive price trend - heading back to the 52-week high of around £8.50 (which I dithered on and missed). However, the yield cover has crumbled away, meaning that there should be a flashing red light on this share for DIY Income Investors.
Momentum being what is it, the price may well continue upwards but today Gnasher said "sell": 41% capital gain is too attractive a bone to just leave lying on the street.
[Sell price: £8.34]
