Answer:
If you had purchased 10 shares of GoPro at the IPO (Initial Public Offering) on June 26, 2014 at 31.34, you would have spent $313.40.
If you were more of a “gambler” than an “investor”, and you saw the market shoot up for GoPro and hit 86.97 just 3 months later and decided to SELL, you would have recognized a capital gain of $869.70 - $313.40 = $556.30.
This would have resulted in a YIELD of ($556.30 / $313.40) x 100 = 177.5%.
Let’s say you hung on to your 10 shares of GoPro, believing that it would get even better. Today it is listed at 4.42. If you were to sell, you would recognize a loss of $44.20 - $313.40 = -$269.20.
This would result in a YIELD of (-$269.20 / $313.40) x 100 = -85.9%.
The average annual yield for 5.5 years would then be -12%.

Explanation:
1 + 0.859 = (1 + r)⁵°⁵
⁵°⁵√1.859 = ⁵°⁵√(1 + r)⁵°⁵
1.12 = 1 + r
r = -0.12 (since the yield was negative, r must be negative)
