Analysis & Notes #
IBKR Performance Deterioration: The portfolio lost $3,560 in market value this week. RACE was the largest drag, falling $2,711 alone as the stock declined from $393 to $366. The stock portion of the portfolio is now down $22.8K unrealized, compared to $19.8K last week.
Option Writing Continues: The covered call positions (RACE Jan16 26 400C and UBER Jan16 26 92.5C) showed improved mark-to-market values this week, adding $2,044 combined. This partially offset the stock losses.
ZBHY Replacement: The ZETA position was replaced with ZBHY (same strike/expiry). Both are now completely worthless, representing a $6,316 loss.
Binance Outperformance: Ethereum’s 1.11% daily gain ($996) drove the Binance portfolio to a +$3,135 week. ETH now represents 41% of the Binance portfolio at $90,517.
Cash Deployment: Buying power decreased by $24K, suggesting capital was deployed into the market during the week.
