This is an actively managed equity ETF that selects undervalued value stocks from a contrarian perspective, pursuing capital growth and current income together. It places no restrictions on market capitalization, adds holdings at the management team's discretion, and is classified in the US large-cap value category.

It suits investors who want exposure to undervalued stocks by relying on the management team's value-selection skills rather than on an index.

It is an ETF managed by Invesco using an active management approach.

The fund does not track a specific index. Instead, the management team picks stocks it judges to be undervalued, using a contrarian approach. It holds a broad range of companies that look undervalued from a value perspective, regardless of market capitalization, and aims for both capital growth and dividend income. Additions and weighting adjustments are made at the management team's discretion.

• Active strategy based on contrarian value selection
• Broad stock selection with no market-cap restrictions

Assets under management (AUM) total $184.8M, and the total expense ratio is 0.35% per year.

Management fees are somewhat higher than those of index-tracking core ETFs, and performance depends on the management team's selection skills.

Performance in the value category tends to fluctuate with interest rates, the economic cycle, and relative strength versus growth stocks. Because of the nature of an active selection strategy, the fund may move differently from the market average, so its trend varies by period.

Fund flows into active value ETFs vary with market conditions, and demand tends to diverge between periods when growth stocks lead and periods when value stocks recover. As this is a relatively newly listed category, fund flows should be observed alongside management performance.

Its strengths are the management team's value-selection skills and market-cap flexibility, while its weaknesses are the burden of active fees and performance uncertainty.

BLCR, EAGL, AVLC, and OAKM, shown in the table, are active or core ETFs in the same US large-cap category, and they are natural comparisons in terms of management style and fee level. For broad value exposure at a low fee, you could also consider the value-style ETFs VTV and SPYV, or IWD, which tracks a US large-cap value index.

Here are the points to review before investing in CSTK. Because this is an active value ETF, it is wise to check in advance the fee burden, management performance, and suitability for the current value-stock cycle.

An active selection strategy may underperform the market average depending on management results, and a value strategy may lag when growth stocks lead. The cumulative effect of fees over the long term should also be taken into account.

This is an active ETF suited to investors who want to rely on the management team's value-selection skills rather than on an index. If your priority is broad value exposure at a low fee, it is also worth comparing index alternatives such as VTV and SPYV.
