This Blog Series covers some pretty complicated stuff and I recommend that you read Parts 1 and 2 before you attack this one - you can find them here:

This subject is quite complicated so if you have not read the first Part then it is probably best to look at that first - you can find it here:
http://wheeliedealer.weebly.com/educational-blogs/the-mechanics-of-a-trade-part-1-of-3 Example 2 - You want to buy 3 Shares in Company XYZ but this time you use a ‘Limit Order’ The basic Assumptions are as I listed at the start of Example 1. This time you still want your 3 Shares in XYZ but because it got kicked back at you in Example 1, you have decided to use a Limit Order through your Broker, where you indicate a maximum Price you are prepared to pay for the Shares. For this one, here are the steps as your Order flows through the various Processes:
It’s funny the things in life than can really get under our skin and something that really grates with me is when I see people on Twitter sending out a Tweet to the effect of “A big Buy for 200,000 Shares just went through on XYZ……” (heck, even just typing this is getting my Blood Pressure up !!).
Apart from the fact that the vast majority of people who Tweet sh*te like this are probably Rampers (or perhaps they are just not very clued up on what is really going on), the big issue with this is that if there is a Buy for any Shares then it is a simple truth that there is always one or more Sells on the other side. So if you are taking notice of a Buy Trade and thinking that this is a good thing, then you must be making the cognitive leap that whoever was on the Buy side knows more than whoever is on the Sell side. Without knowing who the individuals are, that is obviously impossible to know and even if you did know who was Buying, you are making an assumption that they are correct (no one is 100% right - even Warren Buffett gets things wrong).
Following on from a different Blog I put out recently that was inspired by some text written by Chris Dillow in Investors Chronicle, again I have been reading one of his Articles and taking inspiration from it. This one appeared in the Magazine from 13th July to 19th July 2018 which had ‘Income Majors’ on the front cover and the Article was entitled ‘In the genes’ and appeared on Page 16. If you are a subscriber to the Magazine then I suggest you go onto the online version and do a search for the article because it is well worth reading. Having said that I have reproduced a few sections of the text here so this will give a good flavour of what is in it.
The starting paragraph is based on some Research that had been done which suggested that Investment Performance was related to our genetic make-up (presumably intelligence levels and Chris mentions the genetic factors that increase our potential Educational Attainment) and that factors such as ACTUAL Educational Attainment, Income Levels and inheritance had less influence. So this suggested that our genes predict how well we save and invest and further on in the article he mentions that such Genetic Factors explain about a third of our Investment Results; and I take from this that at least a part of the other two-thirds is down to how we manage our Portfolios in terms of things like Running Winners, Chopping Losers, Averaging Down at the right time, Avoiding AIM Garbage, TopChopping, Risk Management, Hedging, etc. And of course another chunk of that two-thirds will be down to pure dumb Luck (but if we control as much as possible of the other stuff then the Luck is less of a hindrance and of course sometimes we will get Good Luck which is the sort I like !!). |
