Source: SEC Form 13F-HR. Positions are as-of quarter end (filed up to 45 days later) and cover US-listed equities only — shorts, non-US listings and most derivatives don’t appear. Values as reported by the filer. “Our call” is TENK/calls’s independent SEC-grounded verdict, not the fund’s view.

Research and education only — not financial advice. TENKis not a registered investment adviser or broker-dealer and gives no personalized advice. Every call is impersonal — identical for all users, generated on a schedule from SEC filings plus a delayed/third-party price feed — may be wrong or out of date, and is not a recommendation to buy or sell any security. The operator and an affiliated trading operation may hold or trade the securities TENK rates; see Disclosures. Past performance does not guarantee future results. Do your own research.
