MZOR- example what NOT to do

I lost $500 on this because I didn't stick to the trend guidelines and continued to hold despite what the chart was telling me. I believe MZOR is a great company, innovative product, no debt, however it did recently receive a downgrade which contributed to the downfall in price. With current weakness in the market in which only the strong survive, MZOR was mercilessly sold off. I really liked this stock but it pays to stick to the rules during exuberant irrationality.
