I wouldn't look into it too far there Percy. The great John Maynard Keynes once said "When the facts change, I change my mind. What you you do sir?"
I have had to make a few calls like this myself this year and just remind myself that there is no place for ego in the market. Back yourself when you see a good entry and don't be afraid to sell if your wrong :D
With MVN, all I need to see was:
FA - a good result, a upbeat forecast and the last 3 years of good dividends
TA - a solid support area (will now be $1.05), no down trend and positive price/volume action today.
= Low downside risk, good dividend and potential for further upside (looking forward to the AGM update Nov)
