What it means
An exchange-traded fund, or ETF, is a basket of investments that trades on a stock exchange like a single share. SOXX follows an index (a published list that tracks a group of shares) of semiconductor firms, so its value rises and falls with those companies.
Semiconductors are the building blocks of modern electronics, so the sector reflects demand for technology, data centres and devices. Chip companies can be very profitable in good times, but their earnings swing as demand and inventories change.
Investors use an ETF like this for diversification within a sector, convenience and low cost. They avoid having to choose which company will win, though they still carry the risk that the whole sector falls.
The convenience of a single trade also makes it easy to rebalance. Funds charge an annual fee called the expense ratio, taken from the fund's assets, and the investor also faces trading costs.
The ratio is small compared with many actively managed funds, but over many years the fee still reduces returns. Concentration is the main risk.
A few large companies often make up a large share of the fund, and the sector depends on global supply chains, government policy and a few key customers, so one event can move the whole fund. Check the fund provider's current factsheet for the index followed, holdings and fees, because these details can change.
Nothing here is investment advice.
In practice
Real-world examples.
Example
A technology company's chief financial officer wants to invest part of a long-term employee reserve in a sector fund. After a board discussion, she allocates a small percentage to a semiconductor ETF, while keeping most funds in broadly diversified holdings to limit risk. The board agrees that no more than 5% of the reserve may sit in any one sector.
Example
A self-employed consultant believes demand for chips will rise because of artificial intelligence and data centres. Instead of choosing one manufacturer, she buys a semiconductor ETF share so that she benefits if the sector grows even if her favourite company stumbles. She accepts that she will also own companies she does not particularly like.
Example
A financial adviser reviews a client's portfolio and notes that already 30% sits in technology shares. Adding a chip sector fund would increase the overlap, so she recommends a smaller allocation than the client first planned. She documents the discussion so that the client's final choice is recorded.
Formula
Calculation
Annual fee cost = investment value x expense ratio
Value after one year = investment value x (1 + return) - annual fee cost
An investor puts $50,000 into the fund, which has an illustrative expense ratio of 0.35%. The annual fee cost is 50,000 x 0.0035 = $175. If the fund's holdings rise 12% in the year, the gross value is 50,000 x 1.12 = $56,000. Subtracting the fee gives 56,000 - 175 = $55,825, which is a net gain of $5,825 or 11.65%. In a falling year the same fee would be charged on a smaller balance, so the cost is not tied to performance.Case study
Seen in the real world.
Halden Capital is an illustrative, fictional family office that held a diversified portfolio but wanted modest exposure to technology. The investment lead recommended placing 5% of a $10,000,000 portfolio, or $500,000, into a semiconductor ETF.
In the first year, chip demand slowed and the fund fell 25%, reducing that holding by $125,000. Because the position was only 5% of the portfolio, the overall portfolio fell by about 1.25% from that holding alone.
The illustrative lesson was that sector funds can be very volatile, yet position sizing limits the damage. The family office kept the holding, rebalanced when it grew too large and reviewed it at least once a year. The investment lead wrote a short rule that any holding above 7% of the portfolio would be trimmed back.
Watch out
Common mistakes.
- Assuming an ETF is automatically low risk, when a sector fund can be as volatile as the industry it tracks.
- Ignoring overlap with other holdings, so a portfolio becomes heavily concentrated in the same few technology companies.
- Looking only at past returns, which can be unusually high or low and do not predict the next period, and a sector that has just surged may be due for a pause.
Questions
People also ask.
What does SOXX stand for?
It is simply the ticker symbol used on the exchange, and it is linked to the semiconductor theme of the fund.
How is an ETF different from a mutual fund?
An ETF trades throughout the day on an exchange like a share, whereas a traditional mutual fund is usually bought or sold once a day at a set price.
Does the fund pay dividends?
Funds of this type typically pass on the dividends received from their holdings, but the amount varies, so check the provider's information.
