Investors should learnThe big mistake of any investor is that they let emotions dictate the pace of their investment. They read about hold for long time, etc...
The most important lessons are:
-never borrow to invest
-don't foget to take profit
Many people lost their shirt and mortgage their house because of using leverage to borrow.
When VMD was at $11,10, 9, 8 etc....you should have taken profit. When the stock move from $3 to
$9 you better believe that this is a 200% profit, when it is at $3.85 there is no profit and at $2 you loose 32%.
It is a bit late for non sophisticated greedy investors to correct the mistake but its a valuable lesson.
