Wisestguy,
I disagree very slightly with your post (no. 61) about holding losing shares in a portfolio. If one has a £100,000 portfolio of shares and at the end of the year the realisable value is £60,000, then there is a paper loss of £40,000 or 40% even though the loss has not been realised. If one had been unfortunate enough to buy Japanese shares at their peak 20 years ago, one would be carrying losses forward every year and your portfolio would reflect this at the end of each accounting period.
To take it further, if you had also made £50,000 trading alongside your portfolio, your net gain for that year would be £50,000 - 40,000 (unrealised losses) = £10,000. If you were registered as a trader with the Inland Revenue, that is the way they would prefer to treat your situation for tax purposes. Also, if you were managing funds for other parties, you would reveal all the information.
Nevertheless, we are all agreed that one can manipulate data and figures to suit one's purposes and this is why long term investors have to check carefully before buying shares.
