Colm, I have been caught on the naughty step a few times in the past, hence my title - please read it backwards
I agree with your philosophy. Having carried out due diligence, and seeing rising momentum in the share price, the trend is your friend - until the story changes.
We can only rely on the accuracy of published data and, if lucky, the chance to look at the whites of the eyes of the executive directors in open forums, such as AGM's, where you can assess their competence by raising questions and viewing performance in the flesh.
Having taken an initial position, it is not unreasonable to increase the size of holding, by degree, particularly when momentum is on your side.
Sadly the old card trick of 'adjusting the pack' has been played in this case.
It is now common the quote both adjusted and reported figure. Which to believe? The factual number, arrived at on the reporting date or the one dressed up to make the reader believe that all is right with the company and to just ignore the adjustments, because they will just go away.
Hmmm... You are absolutely correct to look at the cash position. That does not lie, it is either in the bank, or it isn't.
It has become all too easy to hide indiscretions and problems under the heading of adjustments, and to make believe that they are non-recurring. In most cases, they are there for good reason. The numbers quoted are subjective. The auditors will have looked at the arguments put forward, to justify the numbers. The final outcome will usually only be known, somewhere down the track, when the problem has been addressed, and the money spent. Again, it is easy to window dress spending to flatter the outcome, losing attributable costs within normal operating expenses.
It is then a value judgement to let go of the holding. If it subsequently bounces, you kick yourself for jumping too soon, but how many times do you see a share re-rated downwards, and then continue to fall even further.
Once the story changes, for the worse, caution is the by-word. Better to lose 6,7 or 8% than 60,70 or 80% plus!!
By preserving the remaining capital, you have a better start point for the next train that comes along.
Good hunting
