Stock Market Prediction

I'm testing a new method of making a close-enough guesstimate of Nasdaq QQQQ stock index and here are my positions tomorrow. Disclaimer: This is in NO way valid and/or sound stock advice, so trade at your own risk.

Buys:
MNST: 51.39, predicting at least 2% up tomorrow
AMAT: 17.92, predicting at least 1% up tomorrow
JOYG: 69.63, predicting at least 1% up tomorrow

Shorts:
CA: 24.77, 1% down
TMIC: 36.35, 1% down
TLAB: 16.13, 2% down

Again, these are experimental predictions, do not use as actual trading advice.
