At Optarix, like everywhere else, we monitor how share prices
are doing for all positions that we already own or companies that we might be
interested in. And while we enjoy if a positions goes up in price, we are
equally aware that prices can come down, too. There always seem to be shares,
sectors, industries, geographies, etc. that are in favor or out of favor. As a
result companies may be overvalued or undervalued. In almost all cases we don’t
know if that is the case. We don’t know if selling or buying will be at a good
price. We know that for any given trade we will not get the timing right.
On the other hand, with enough trades over time and
following a set of rules, on average we get acceptable prices when we sell or
buy. One of the rules that we use is that we sell stocks when their price has
increased by a certain percentage. This percentage is not fixed and depends on a
number of other factors, e.g. the share of the position in the overall
portfolio.
Let’s look at our position in T. Rowe Price (TROW). We bought
shares in July 2016 at a price of about USD 74.00. Their share price has
developed quite nicely. Along with that the size of their share in our US portfolio
increased as well. As that share increases, the risk associated with this
single position increases as well. We don’t mind taking risks. However, we aim
at taking calculated risks. In this case, we decided to reduce our position to
some degree. We sold shares at about USD 125.00 which represents a realized
gain of 68.92% since July 2016. This is quite a decent result and it freed up
some cash that we then used to start a new position in a company that we
believe is a good addition to our portfolio. At the same time we reduced our exposure
to TROW.
Another aspect is timing. There is very well the case we got
the time wrong. Perhaps we sold too early. In that case we continue to
participate in the share price increased with the remainder of our position,
admittedly to a somewhat smaller degree. Perhaps we didn’t sell enough and
there is some bad news around the corner. We are not aware of any and don’t
want to start a rumor either. But there’s always this thing call “black swan”
event. How do we know what we don’t know? And in case that should happen and
TROW’s price isn’t going anywhere, we have now taken some of our money off the
table and put it into a new position that helps us spreading the risks.
We posted about the approach of taking some money off the
table previously when we discussed our position in Brown-Forman (BF.B). Looking
at that example and now TROW, here is a table with the realized gains of these two
examples:

Please note, that this performance is the past. And while we
aim at having an annualized performance similar the S&P 500, we are only
interested in the long-term performance. These examples are intended only to
demonstrate a technique that helps with the following:
- Rebalance your portfolio in terms of risk and potential,
- Decide when to sell some of a position,
- How to reduce exposure to a given position
- Free up cash to increase a different position or to start a new position
We’ll also share information where we bought additional
shares in a company because we got the timing wrong because the price decreased
after the start of the position. Fundamentally we think that most of the time we
get the timing wrong, so will use approaches that average out such transactions
long term.
Happy investing!
