Advent Capital Management holds a diversified book of 203 stocks worth $3.4B as of Q1 2026 (disclosed May 7, 2026, a ~45-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 equity 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 equity book. Cloning the disclosed picks since 2013 would be +45% (+3.0%/yr). That is a simulation of the disclosed long book, not audited returns.

Growth of $10,000 cloning Advent Capital Management's disclosed long 13F book, rebalanced on each filing date (so it reflects the ~45-day reporting lag, 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 equity book, weighting, concentration and sector figures above.
