Blume Capital Management, Inc. holds a diversified book of 356 reported positions worth $674.4M as of Q2 2026 (disclosed Jul 27, 2026, a ~27-day 13F lag). This quarter Honeywell Aerospace Inc first appears in 13F filings (one of 3 new listings in the book), a listing rather than a purchase; they opened C&S Fut Of Energy Active ETF and trimmed Alphabet Inc-CL C. Their largest long position is Alphabet Inc-CL C at 6% of the reported non-option book. They also disclosed $9.3M in put options (a bearish bet) and $2K in call options (bullish), shown separately below and excluded from the non-option book. Cloning the disclosed picks since 2024 would be +53% (+25.5%/yr). That is a simulation of the disclosed long book, not audited returns.
Following at the filing date actually beat the quarter-end book by 3.6 points over this window.
Growth of $10,000 cloning Blume Capital Management, Inc.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~27 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.

Put / call positions from the 13F — totals include every disclosed option leg
| Type | Underlying | Notional value | Underlying shares |
|---|---|---|---|
| PUT · bearish | SS SPDR S&P 500 ETF TRUST-USSPY | $7.5M | 10K |
| PUT · bearish | INVESCO QQQ TRUST SERIES 1QQQ | $1.8M | 3K |
| CALL · bullish | ODDITY TECH LTD-CL AODD | $2K | 100 |
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.
