Tortoise Investment Management, LLC holds a diversified book of 252 stocks worth $1.3B as of Q2 2026 (disclosed Aug 7, 2026, a ~38-day 13F lag). This quarter they opened AB New York Inter Muni ETF and trimmed Ishares Core S&P 500 ETF. Their largest long position is Ishares Core S&P 500 ETF at 8% of the equity book. They also disclosed $48K in put options (a bearish bet), shown separately below and excluded from the equity book. Cloning the disclosed picks since 2025 would be +8% (+10.4%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Tortoise Investment Management, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~38 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: diversified book

Put / call positions from the 13F — totals include every disclosed option leg

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.
