ION Fund Management Ltd holds a focused book of 52 reported positions worth $845.3M as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter they opened Veeco Instruments Inc and trimmed Solaredge Technologies Inc. Their largest long position is Teva Pharmaceutical-SP ADR at 17% of the reported non-option book. They also disclosed $729.9M in put options (a bearish bet) and $1.6M in call options (bullish), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2026 would be +20% (+37.0%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +25.8%, a 5.7-point gap that is the cost of the ~45-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning ION Fund Management Ltd's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~45 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.

13F filers disclose option positions at the market value of the underlying the contracts reference, not the premium paid. A put is a bearish bet (it gains if the stock falls); a call is bullish. “Underlying shares” is the share count the contracts control, not a share holding. These legs are excluded from the non-option book, weighting, concentration and sector figures above.
As-of date vs the date the SEC received each filing
Reported 13F total per quarter. Raw filing totals can include option notional.
Holdings from SEC EDGAR 13F-HR filings, updated quarterly, filed up to 45 days after quarter-end. Public domain. Book totals and portfolio weights cover reported non-option positions, which can include notes and warrants. Disclosed put/call options are listed separately and excluded from those totals. The performance line is a simulation of the disclosed long book, not an audited return.
