Gu Jingci: Gold's rebound and short positions also yielded good profits, while SanDisk's short positions maximized their potential gains.

The short positions in gold, initiated again this afternoon above 4400, have now reached below 4360 and still offer considerable upside potential. Most importantly, the short position in SanDisk near 1740 has already hit 1614, maximizing the potential profit. However, Bitcoin has risen instead of falling, so we'll have to wait for the trend to emerge overnight.
