Oak Grove Capital LLC holds a focused book of 97 stocks worth $1.4B as of Q2 2026 (disclosed Aug 13, 2026, a ~44-day 13F lag). This quarter they opened Devon Energy Corp and trimmed Coherent Corp. Their largest long position is Micron Technology Inc at 22% of the equity book. They also disclosed $444K in put options (a bearish bet) and $741.5M in call options (bullish), shown separately below and excluded from the equity book. Cloning the disclosed picks since 2025 would be +48% (+62.1%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +59.8%, a 11.7-point gap that is the cost of the ~44-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Oak Grove Capital LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~44 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.
Top-heavy: focused book
Share of the disclosed book in its largest positions. A higher top-5 share means a more concentrated, higher-conviction portfolio.

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 equity book, weighting, concentration and sector figures above.
As-of date vs the date the SEC received each filing
Holdings from SEC EDGAR 13F-HR filings, updated quarterly, filed up to 45 days after quarter-end. Public domain. The book and weighting are long equity only; 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.
