What would have been the percentage wealth gain for a trader, who bought equal numbers of all bullish shares at opening price and sold them at their day’s high?

Stock	Opening	Close	High	Low	Trend
A	2200	1800	2400	1200	Bearish
B	2000	1700	2000	1400	Bearish
C	800	1200	1400	800	Bullish
D	500	1000	1200	300	Bullish
E	1300	1100	1400	1100	Bearish
F	1800	1600	2000	1200	Bearish
G	1200	1700	1900	1000	Bullish

From the table, there are three bullish stocks: C, D, and G.

A trader buys 1 share of each bullish stock at the opening price and sells them at the highest price of the day.

Stock	Buy	Sell
C	800	1400
D	500	1200
G	1200	1900

For stock C:

$\small\dfrac{1400-800}{800}=\small\dfrac{600}{800}=\small\dfrac{3}{4}$

---

For stock D:

$\small\dfrac{1200-500}{500}=\small\dfrac{700}{500}=\small\dfrac{7}{5}$

---

For stock G:

$\small\dfrac{1900-1200}{1200}=\small\dfrac{700}{1200}=\small\dfrac{7}{12}$

---

Total money spent = $800+500+1200=2500$

Total money received = $1400+1200+1900=4500$

Overall return:

$\small\dfrac{4500-2500}{2500}=\small\dfrac{2000}{2500}=\small\dfrac{4}{5}=0.8=80$

---

So, the trader makes an 80% total return.
