The key to this is deciding: what is the ideal number of different investments we should hold at any one time?. This is a balancing act.
Risk and reward: As a club we do need several different investments in order to spread our risk, but if we have too many our portfolio starts to look like a tracker fund and we're reducing our chances of beating the market.
Dealing costs: Spreading our money across a large number of shares costs slightly more, due to one-off dealing costs
Analysis: It's harder to keep track of a large number of shares and decide which to sell and which to keep
So it's something we need to decide on, and the ideal number may change as the club grows. In our old club, what we did was something like this:
I think we decided on 5 as the optimal number of investments to hold at any one time. Every month, we would either buy or sell a share. Initially, we would always buy - until we reached our optimum number of shares (5). From then onwards, we would alternate between buying and selling so we always had around 5 investments at any one time. The procedure for selling was similar to that for buying: according to a rota (but sometimes with volunteers), 3 members would each be asked to nominate a share to sell (from our existing holdings). A poll would run for a set time (a week or so), and then we would automatically sell the share that received the most number of votes (chairman gets the casting vote)
Now you might say that this approach lacks flexibility. What if you one month it didn't seem like a good idea to sell any of our shares? A natural concern, and we found that members were ,always keener to buy a new share than sell an old one.
But I would argue that, as an online club, we benefit from having a fixed process that forces us to choose - and hence means we don't get tempted to build up too many different investments. It also releases funds for us to invest in a new share
The questions of how much to invest and how often do we buy/sell are interrelated. It makes sense to try to spread our money as evenly as possible across our investments, but it will not always be practical to do this.
In the short term, our club can't commit to monthly buy/sell decisions because we don't know the level of funds that will be available. But what we can do is come up with a formula that says "We make a new investment once our cash balance exceeds the average of our existing holdings."
Let's say for the sake of argument we decided on a target of 5 investments. We currently have 4 (we should ignore our holding in Share PLC for this purpose) worth a total of £2267.25 - an average of around £567 per holding. So as soon as we have at least £567 in spare cash to invest, we should do so.
Once we go above our optimal number of investments (i.e. we reach 6) then the next decision we take should be to sell one of them. So our number of holdings will then keep switching between 5 and 6 as we buy and sell.
The advantage of this approach is that we have fixed criteria for when we are supposed to make buy and sell decisions, rather than relying on someone to start a discussion and then debate it at length bfore we even get any share nominations! I think an online club such as ours can only be workable with fixed rules like this.
What does everyone think about this approach?
BTW When I do our next valuation (next weekend) I expect we'll have enough funds to make a purchase under the above formula. So the sooner we agree on this process and get a next set of nominations, the better
