The fund is managed by Global X, trades on Nasdaq in U.S. dollars and launched on Oct 25, 2019. On Nov 9, 2026 it held $2.07B in net assets and its expense ratio was 0.50%. BUG is a low cost fund of cybersecurity companies.
Investors search for BUG ETF because they want a clear answer to four practical questions. What does it cost to hold each year, what does it pay, what is actually inside, and how does it fit in a Roth IRA, a traditional IRA or 401(k), or a taxable account. This guide answers each one with dated figures from the issuer, and marks anything the issuer page does not publish as Not captured.

What BUG holds.
The 10 largest stock positions inside BUG, as of Nov 9, 2026. Pick a number to see how much of the fund they make up.
The ten largest holdings and the group split are shown below from the issuer page. A theme fund puts much more weight on a few industries than a broad market fund does, so a handful of names can move the whole fund.
BUG yield and distributions.
BUG has paid once a year, in late December or early January, with one extra payment in mid 2020, which makes it an annual payer. The issuer page showed a yield of -0.25% SEC (Nov 10, 2026). The most recent payment in the log was $0.0119 per share with an ex-date of Dec 30, 2025.
A yield is a snapshot, not a promise. The payment moves each period with the dividends and interest the fund receives, and some years include capital gains or return of capital that do not repeat. Read the year by year table below before building a plan around a single quarter. If you reinvest distributions, the payment still counts as income for tax purposes in a taxable account.
Recent distributions per share
Total distribution per share is shown on each bar. A tinted bar includes a reinvested year end amount.
Every payment, and the year by year record.
The ex-date is the cut-off, so you must hold shares before it to receive that payment. Amounts are per share in U.S. dollars from the issuer page.

What BUG costs to hold each year.
The expense ratio of 0.50% means the fund keeps about $50 a year for every $10,000 you hold. That cost is taken out of the fund price in small daily amounts, so you never see a bill, but it lowers your return every year. Over ten years on a flat $10,000 the expense ratio adds up to roughly $500, before any growth.
Two other costs sit outside the expense ratio. Trading commissions depend on your brokerage, and most large U.S. brokerages now charge nothing to buy ETFs. The bid and ask spread is a small cost you pay each time you trade, and for the largest funds it is usually tiny.
Expense ratio cost at common amounts
| Amount held | Per month | Per year | Over 10 years, flat | Hypothetical 2.00% fund, per year |
|---|---|---|---|---|
| $1,000 | $0.42 | $5.00 | $50 | $20 |
| $5,000 | $2.08 | $25.00 | $250 | $100 |
| $10,000 | $4.17 | $50.00 | $500 | $200 |
| $25,000 | $10.42 | $125.00 | $1,250 | $500 |
| $50,000 | $20.83 | $250.00 | $2,500 | $1,000 |
| $100,000 | $41.67 | $500.00 | $5,000 | $2,000 |
| $250,000 | $104.17 | $1,250.00 | $12,500 | $5,000 |
Flat estimates at the current expense ratio with no growth and no change in fee. Trading commissions depend on your brokerage and are not included. The 2.00% fund is a hypothetical used for scale.
Where the cost shows up
- Not as a bill. The share price and returns are already lower by the expense ratio.
- Trading cost shows up as the bid and ask spread each time you buy or sell, and as a commission if your broker charges one.
- In a taxable account, dividends are reported on Form 1099-DIV and taxed in the year they are paid.

Sector exposure
What the ride can look like.
BUG can lose value, and the period returns from the issuer show the range so far.
- Market risk. The fund falls when stock markets fall.
- Industry concentration. The fund depends on one industry or theme, so a setback there hits the whole fund.
- Concentrated holdings. A few large companies carry a high share of the weight.
- Valuation risk. When prices rise faster than company earnings, later returns can be lower or negative.
- Distribution risk. Payments are small, change each period and are not guaranteed.
How investors use BUG.
BUG is most often used as a satellite holding, a smaller piece added on top of a broad market core. An investor who owns it is choosing to tilt the portfolio toward one industry, which is a bet on that theme rather than on the market as a whole.
Because a theme can lead or lag the market for years, many investors cap it at a small share of the portfolio and rebalance. That choice is worth checking against your own situation.
Before buying BUG, check four things on the issuer page. First, confirm the expense ratio matches the figure on this page, since fees can change when an issuer cuts costs. Second, confirm the fund is eligible for the account you plan to use. Third, read the latest tax breakdown if you hold it in a taxable account. Fourth, look at the bid and ask spread on the day you trade, since a wide spread is a cost that the expense ratio does not show.
Several comparable funds exist, with expense ratios of HACK at 0.60%, CIBR at 0.58%, ITA at 0.37%, XAR at 0.35%, so weigh cost together with what each fund holds, how it pays and the account you use.
No single fund is right for everyone, and this guide describes the product rather than recommending it. The figures come from the issuer and are dated. Distribution amounts, yields and holdings change, and past returns do not predict future returns. For a decision with large amounts of money, read the prospectus and the shareholder reports, and consider speaking with a licensed adviser about your own situation.

Where BUG fits.
Qualified withdrawals from a Roth IRA are tax free, so dividends and gains compound without a yearly tax bill and the expense ratio is the main drag you carry. BUG is an ordinary exchange traded fund, so most brokerages let you hold it in a Roth IRA.
Tax is deferred until you withdraw, and withdrawals are taxed as ordinary income. A 401(k) offers only the funds on its menu, so check whether BUG or a similar fund is in your plan.
Distributions are small for most theme funds. Dividends that meet the holding rules are taxed as qualified dividends at lower long term rates in a taxable account, the rest is taxed as ordinary income, and gains are taxed when you sell. Your broker reports the amounts on Form 1099-DIV after year end, and those figures are what count on your return. ETFs also tend to pass out few capital gains because of how shares are created and redeemed.
General education, not tax advice. Rules change, so confirm with the issuer tax documents or an adviser.
Buying BUG in five steps.
- Pick the account. Roth IRA, traditional IRA, 401(k) or taxable. Most brokerages let IRAs hold ETFs like this one.
- Search the ticker. Type BUG in your brokerage and choose the U.S. listing, priced in U.S. dollars.
- Use a limit order. It sets the most you will pay and avoids surprises at the open.
- Check the cost. Most large U.S. brokerages charge no commission on ETFs, and some charge a small fee per trade.
- Set a routine. Add money on a schedule and decide whether to reinvest distributions.
