Finally, December has arrived, and it has been a very quiet month with not much volatility. Let’s review the performance and see where we stand before closing the year within the next week and half.

Realized P&L & Win Rate

Since inception, I have realized 14 trades:

🟢 8 Winners
🔴 3 Losses
🟡 3 Break-even (+/- 3%)

This translates to a 73% win rate when excluding break-even trades, or 62% including them. The top three trades, percentage-wise, have been $BABA, $TSLA, and $OSCR, each delivering between 31% and 40% from entry to exit.

Realized losses have so far been modest, with a maximum realized loss of just 7.2%. These results will change once I start realizing profit and loss for the open invalidated positions such as a massive drawback in a $NVO trade.

Summary

December price action so far has been quite slow with not much volatility, and I am not realized any trade in the past month except opened a new trade in $NVO. I’ve yet had the chance to realize the loss in the previous trade, but with the current price action, I believe I will be able to close it close to my entry point. Although that might take some time, so for now, that loss is holding up my cash position. But as I feel confident I will be able to realize a slightly lower loss, I’m happy to carry it for the next coming months. I might have seen it a little bit different if this was a trading account with no monthly deposits. But since I’m having additional cash deposited on a monthly basis, it makes it easier to take a bit of a more risk approach to realizing losses in the portfolio.

On a trading mentality basis, I feel strong moving into the end of the year, and I’m happy that I’ve almost continued this experiment for almost one year. It will be very interesting to see where we close the end of the year in the next week and a half.
