Hedging with S&P 500 Index Futures

SIF hedging: NF = V_F(antiguo) = F_o x Z. NF (Number of contracts) = V_p (portfolio value) / (V_F x B_p) (Beta). With this hedge, risk is removed. If the index goes up, the profit in the portfolio will be offset by losses in SIFs contracts and vice versa.

Example: S&P 500 falls 5%:

• In the portfolio: R_p = B_p x (-5%) = -10% of a portfolio of $10M, resulting in $9M (Final Value).
• In the SIFS contracts: S_i = 980 (S&P 500 value given) x 0.95 (100% - 5%) = 931. F_i = 931 x (1 + 0.04 x 5/12 (next month timeframe)) = 946.52. V_F = NF x (F_i - F_o) x Z (250).
• Gain on futures: V_F(New) / Equity portfolio value.
• Outcome stock portfolio: 2 x (-5%) = -10%.
• Final Value portfolio: $10M - $1M + V_F(New).

What is a Firm?

Let us now try to understand the meaning of a 'firm'. A firm is a focal point of the production system of any country. A firm produces goods with the help of its own resources. Sometimes these resources are borrowed from outside, and they are paid remuneration (price) for using them, for example, land, labor, capital, etc. A firm is an organizational unit, while a plant is a 'technical unit'. The objective of a firm in organizing such factors of production is to maximize profit. In other words, profit is the main objective of a firm. Any decision of a firm is taken in accordance with this objective.
