Suppose that you have $11,000 your investment decreases 60% and then increases by 70%. your advisor tells you that you had a 10% increase on your 11000 investment is he right or wrong and whats the correct gain or loss.
A SPECIFIC amount here DOESN'T matter. In other words, the $11,000 is irrelevant.
After a 60% reduction, itw's valued at 40% (.4) of its original value
After a 70% increase, itw's valued at 68%, or .68 (.4 * 1.7) of its original value
At 68% of its original value, it has lost 32%, or .32 (1 - 68%, or 1 - .68) of its original value.
Answer: The advisor is definitely wrong and should no longer be your advisor, in my opinion.
