Advent Capital Management holds a diversified book of 203 reported positions worth $3.4B as of Q1 2026 (disclosed May 7, 2026, a ~37-day 13F lag). This quarter they opened Jetblue Airways Corp and trimmed Bank Of America Corp. Their largest long position is Bank Of America Corp at 5% of the reported non-option book. They also disclosed $31.6M in put options (a bearish bet) and $211.5M in call options (bullish), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2013 would be +91% (+5.2%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +201.4%, a 109.9-point gap that is the cost of the ~37-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Advent Capital Management's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~37 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
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 non-option book, weighting, concentration and sector figures above.
