$iShares Semiconductor ETF(SOXX.US) I'm really annoyed with myself. I clearly knew two days ago that TSMC and NVIDIA would rise, obviously to boost the semiconductor sector. Now almost all 30 stocks in the Philadelphia Semiconductor Index have hit new highs, with gains exceeding 50% within a month. Yet, my position is fully leveraged and shorting semiconductors 3x!!! Down 45 points and I don't want to cut the loss, my execution is really poor. The Nasdaq and semiconductors hit new highs again tonight.
