Recursive Binary Tree Traversals

Inorder Traversal:

void inorder(struct node *root)
{
  if(root != NULL)
  {
    inorder(root->left);
    printf("%d\t", root->data);
    inorder(root->right);
  }
}

Preorder Traversal:

void preorder(struct node *root)
{
  if(root != NULL)
  {
    printf("%d\t", root->data);
    preorder(root->left);
    preorder(root->right);
  }
}

Postorder Traversal:

void postorder(struct node *root)
{
  if(root != NULL)
  {
    postorder(root->left);
    postorder(root->right);
    printf("%d\t", root->data);
  }

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).

Competitiveness and Trade

Nominal Exchange Rates

When our currency's value increases, our competitiveness decreases, and importations increase in relative terms.

Price Levels

• Our Country: If prices in our country increase, our exports decrease, and imports increase.
• Foreign Country: If prices in foreign countries increase, our competitiveness increases, benefiting our exports, and our imports decrease.

Foreign Exchange Market

• Price Determination: The exchange rate between countries is established based on supply and demand.
• Hedging: Protection against currency fluctuations, safeguarding investors and businesses from losses due to currency appreciation or depreciation.

Theoretical Semiannual Euribor:

(1 + First-half rate) * (1 + Second-half rate) = (1 + Annual rate).

Nominal Exchange Rate: (Nominal Exchange Rate * Domestic Price Level) / Foreign Price Level.

Spot Market: Notional amount * (1 / Current exchange rate - 1 / Initial exchange rate). Positive value means that in 9 months the spot market will be more expensive.

FXA (Foreign Exchange Agreement): Notional amount * (1... Continue reading "Understanding Forex, Financial Ratios, and Country Competitiveness" »
