Thank you for your comments. I don't have any major disagreements with what you've written, just modifications/ amplifications.
I don't take a conventional approach to valuing companies. My main criterion is whether I think it will deliver my target return of (say) 6% to 7% a year over the next n years. Like Warren Buffett, my ideal holding period is forever, i.e. n approaches infinity. I recognise that I've erred in not giving enough consideration to the reality of having to sell at some future date, and the uncertainties around what price I'll be able to sell at. I'll come back to this point later.
Looking at Renishaw as a stock to be held forever, the analysis is straightforward. Over long periods, it has consistently delivered double digit growth in earnings and a slightly lower rate of growth in dividends (the lower rate of growth in dividends means that it's now reinvesting a higher proportion of profits back into the business). I only have records for the last 13 years. Over that period, EPS has grown by 13.7% a year on average and dividend per share by an average 8.9%. The period over which that 13.7% average growth rate was achieved spans 2009, when EPS fell 79%, to just 21% of the 2008 figure, but it bounced back the following year and hasn't looked back since.
Unlike most fast-growing companies, growth is almost entirely organic rather than by acquisition. Total share capital now is exactly the same as when I bought my first shares in 1998: no new shares were issued in the meantime, and none bought back. The company has no borrowings; it owns a high proportion of the properties it occupies all over the world, and has over £100 million cash in the bank, so growth wasn't achieved by leveraging up the balance sheet and taking on extra risk - another common, and risky, formula for fast growth.
The formula for growth is, and always has been, to invest around 15% of revenues in R&D each year. The vast bulk of this "investment" is expensed through the P&L account. Thus, a massive asset is being created (in the form of patents, know-how, new products in the pipeline) that is almost completely unrecognised in the balance sheet. Companies sometimes acquire such know-how by buying other companies. They can then recognise the value of acquired R&D in the balance sheet. It's a peculiar quirk of accounting. Renishaw keeps it all hidden away - and is happy to keep it that way.
Because of the durability of the growth formula, I am confident that EPS will continue to grow in future (providing they keep investing 15% of revenue in R&D). I've factored a 9% average EPS growth rate into my calculations. Assuming dividends stay at a constant percentage of profits, I can also expect dividends to grow by 9% a year on average. My desired return is "only" 7% a year, so I'm prepared to pay a good price for that sort of payback.
Of course, the share price will gyrate all over the place, but those gyrations don't affect the above reality. The share price is only relevant if I want to sell (or buy, but I'm now very much a seller). The plan is to sell my shares gradually over the years, taking advantage of elevated share prices to sell, and holding on when it's depressed. I did sell some shares when the price was at £56, but I admit that, while I thought £56 was a bit rich, I didn't think it was mad, so I only sold a small proportion of my holding. Also, as I wrote in my last diary update, I bought back around a third of what I sold when the price dipped below £52. Now that the price is down to £37.82, I'm sorry that I didn't sell more at the higher price, but I'm not going to die of depression over it: I'm still convinced that the growth formula is intact for the longer term. Yes, it will be squeaky bum time if we get a repeat of 2009, because of the problems in China (a major market for Renishaw) but Renishaw is better placed to ride out a severe recession than most other companies (the cash position was boosted by another £15 million since 30 June, to £115 million by the end of September). I hope that I too will be able to ride out a recession - if one comes. Nevertheless, I recognise that, as I get older, I should be giving more consideration than I've given hitherto to the price at which I may have to offload stock. One lesson learned - painfully.
@joe sod: you're right about CGT being a constraint on selling. I'm not going to rail against it; I accept tax as a fact of life, just like the weather. The government would probably get more revenue from this tax if they reduced it: people would buy and sell more, and it would also be better for the economy. Anyway, I'll try not stray into politics. Some of my shares are in the ARF/ AMRF, so I don't have to worry about CGT on those; I also hold some in the spread bet account, which is exempt from CGT, but I repeat what my spread bet providers are obliged to tell me every time they write to me: 78% of their retail clients (79% for another provider) lose money on spread bets, so be warned!!!
