Answer:
Standard deviation = 47.69% (Approx)
Explanation:
Given:
Portfolio of Apple stock w1 = 25% = 0.25
Portfolio of Tesla stock w2 = 75% = 0.75
Standard deviation return Apple σ1 = 35% = 0.35
Standard deviation return Tesla σ2 = 60% = 0.60
Correlation coefficient ρ12 = 0.22
Find:
Standard deviation
Computation:
Standard deviation = √w1²σ1² + w2²σ2² + 2w1σ1w2σ2ρ12
Standard deviation = 0.4769
Standard deviation = 47.69% (Approx)

Investing in bubble can appear to last forever, but because they are formed by self-perpetuated reasons, they eventually fall and the money that was invested into them is lost. In such cases, investors would run to withdraw their money and avoid the loss of fall in share prices.
