To determine the net change in the company's stock price over the four days, we need to aggregate the daily changes as specified:

1. On Day 1, the stock price increased by $3.50.
2. On Day 2, the stock price decreased by $3.70.
3. On Day 3, the stock price increased by $3.30.
4. On Day 4, the stock price decreased by $3.40.

To find the net change, we sum these values:
[tex]\[ 3.50 + (-3.70) + 3.30 + (-3.40) \][/tex]

The arithmetic steps are as follows:
1. Sum the positive changes: \( 3.50 + 3.30 = 6.80 \)
2. Sum the negative changes: \( -3.70 + (-3.40) = -7.10 \)
3. Combine the positive and negative sums: \( 6.80 + (-7.10) = -0.30 \)

Thus, the net change in the company's stock price over the four days is $-0.30.
