In this question, s (t) = 1953.4438+02,
r=4.8%，
d=2.75%，
And the time period is 165438+ 10/9 to 65438+February 19, which is exactly one month, so (T-t)/365 can be directly changed to1/kloc-.
∴
65438+ theoretical price of stock index futures in February =1953.12 * [1+(4.8%-2.75%) *1/2] ≈1.
Then multiply by 1956.4 respectively.
1. Bilateral handling fee 0.3%+ stamp duty 0.65438+ transaction amount 0%+ stock trading impact cost 0.5%.
Secondly, the error of simulated exponential tracking is 0.2%.
Third, the loan spread cost is 0.3%.
Add up the products of these three items respectively, and add the bilateral handling fee of 0.2 on the turnover tax calculation question and the impact cost of buying and selling personal income tax calculation question of 0.2, which is approximately equal to 27.8, and this number plus or minus 1956.4 is the arbitrage-free interval of the enterprise income tax calculation question.
I'll use the mathematical formula to calculate it for you again. 27.8 The specific calculation formula is:
1956.4*(0.3%+0. 1%+0.5%)+ 1956.4*0.2%+ 1956.4*0.3%+0.2+0.2
= 17.6076+3.9 128+5.8692+0.2+0.2
=27.7896
≈27.8
The last interval is (1956.4-27.8 to 1956.4+27.8).
Is the answer to the landlord's question (1928.6,
1984.2)
I hope my answer can help you!
