So they would like to find a way to manage these risks. Hedgers enter a financial market with the purpose of reducing the risk of the transaction. Hedging instruments are available from exchanges, investment banks, insurance firms, and other institutions. • Exchanging assets: The financial market also allows entities to exchange assets assets with other entities. For example: currency exchange • Utilizing information: Investors with correctly analyzed information expect to information earn an additional return by identifying assets that are currently undervalued or overvalued.First function: fulfill different entities’ requirements function• Savings: stocks, bonds, certificates of deposit, real assets, and other assets are tools for Savings saving. Individuals save to gain interest. Firms save a portion of their profits for future expenditures. Borrowing: Borrow money from lenders who require collateral, take an equity position, Borrowing or investigate the credit risk of the borrower to protect themselves in case of borrower defaults. Individuals may borrow in order to buy a house or for other purposes. Firms may borrow to meet their finance capital expenditures and for other activities. Governments may issue debt to meet their expenditures. Issuing equity: Another method of raising capital beside borrowing is to issue equity, equity where the capital providers will share in any future profits. Investment bank help with issuance. Analysts value the equity. Regulators and accountants encourage the dissemination of information.7-161 100% Contribution Breeds Professionalism••8-161100% Contribution Breeds ProfessionalismR.47.1 Characteristics of a Financial MarketSecond function: Determine interest rates• Interest rates are justified according to the total supply of savings and the total demand of borrowings. • Equilibrium interest rate: rate when the interest rate at which the entities are willing to borrow is equal to the amount that entities are willing to lend, we say that the supply and demand are balanced, and such balanced interest rate is called the equilibrium interest rate. Equilibrium rates for different types of borrowing and lending will differ due to differences in risk, liquidity, and maturity.R.47.1 Characteristics of a Financial MarketThird function: Allocate capital to its most efficient uses• Investors have to weigh the expected risks and returns of different investments to determine their most preferred investments due to limited availability of capital. • This would result in an allocation to capital to its most valuable uses.9-161100% Contribution Breeds Professionalism10-161 10-100% Contribution Breeds ProfessionalismR.47.1 Characteristics of a Financial MarketLos d: Describe the types of financial intermediaries and the services that they provideR.47.1 Characteristics of a Financial MarketBrokers, Dealers and Exchange (Cont.)• Dealers: trade by buying for or selling from their own inventory and thus Dealers provide liquidity in the market and profit primarily from the differences of buy and sell prices. Dealers that trade with central banks to affect the money supply are referred to as primary dealers. dealers Broker-dealers: Some dealers also act as brokers. Broker-dealers have an inherent conflict of interest. Brokers: should seek the best prices for their clients; Dealers: are to profit through prices or spreads.Brokers, Dealers and Exchange• • • • • Brokers: Brokers help their clients buy and sell securities by finding Brokers counterparties to trades in a cost efficient manner.

Exchanges sometimes act Exchanges as brokers by providing electronic order matching. Alternative trading systems (ATS): serve the same trading function as exchanges but have no regulatory function, are also known as electronic communication networks (ECNs) or multilateral trading facilities (MTFs). ATS that do not reveal current client orders are known as dark pools. pools (used to reduce market impact)11-161 11100% Contribution Breeds Professionalism12-161 12-100% Contribution Breeds ProfessionalismR.47.1 Characteristics of a Financial MarketSecuritizers• Securitizers pool large amounts of securities or other assets together and sell interests in the pool to other investors. By securitizing the assets, the securitizer creates a diversified pool of assets with more predictable cash flows than the individual assets in the pool. This creates liquidity in the assets, because the ownership interests are more easily valued and traded. There are also economies of scale in the management costs of large pools of assets and potential benefits from the manager’s selection of assets.R.47.1 Characteristics of a Financial MarketSecuritizers (Cont.)• • Assets that are often securitized include mortgages, car loans, credit card receivables, bank loans, and equipment leases. A firm may set up a special purpose vehicle (SPV) or special purpose entity (SPE) to buy firm assets, which removes them from the firm’s balance sheet and may increase their value by removing the risk that financial trouble at the firm will give other investors a claim to the assets’ cash flows.

Such intermediaries are able to do this by pooling policyholders with uncorrelated risk of losses. Insurance firms also provide a benefit to investors by managing the risks: Moral hazard occurs because the insured may take more risks once they are protected against losses. Adverse selection occurs when those most likely to experience losses are the predominant buyers of insurance. In fraud, the insured purposely cause damage or claim fictitious losses so they can collect on their insurance policies.R.47.1 Characteristics of a Financial MarketArbitrageurs• • Arbitrageurs are intermediaries who seek to gain certain return without bearing any risk. In markets with good information, pure arbitrage is rare because traders will favor the markets with the best prices. Clearinghouses: act as buyers when customers want to sell assets and as sellers when customers want to buy assets, and thus limit counterparty risk. Custodians: also improve market integrity by holding client securities and Custodians preventing their loss due to fraud or other events that affect the broker or investment manager.Clearinghouses and Custodians• •15-161 15-100% Contribution Breeds Professionalism16-161 16-100% Contribution Breeds ProfessionalismR.47.1 Characteristics of a Financial MarketLos k. describe the characteristics of a well-functioning financial system A well functioned financial market:• allows entities to achieve their purposes.R.47.1 Characteristics of a Financial MarketLos l. describe the objectives of market regulation.Problems when there are no regulations Fraud and theft: the potential for theft and theft fraud increases because investment managers take advantage of unsophisticated investors.

Secondary precedence rule: if orders are at the same prices, the earliest arriving orders are traded first. Trade pricing rules: are used to determine the price after orders are created using order matching rules. Under the uniform pricing rule, all orders trade at the same price, which is the price that results in the highest volume of trading.

Give a brief explanation of yourobservation.No colonies are found in section C1. The E. coli cells are not transformed with the given plasmid; thus they cannot grow in the presence of ampicillin without the ampicillin-resistance gene.4.What do you observe in section P1 of the agar plate? Describe and explain yourobservation.There are only some blue colonies found in section P1 of the agar plate. This implies that these colonies have been transformed by the plasmids because the plasmids have an ampicillin-resistant gene. Also, these colonies turn blue. This implies that the colonies produced functional beta-galactosidase, and hence the substrate X-gal was metabolized and gave rise to products with blue pigments.5.What do you observe in section D1 of the agar plate? Describe and explain yourobservation.There are some blue colonies and some white colonies in section D1 of the agar plate.These bacterial colonies can grow on the agar plates with ampicillin. This implies that these colonies have been transformed by those plasmids because the plasmids have an ampicillin-resistant gene.Also, some colonies are blue. This implies that the colonies produced functional beta-galactosidase, and hence the substrate X-gal was metabolised and gave rise to products with blue pigments. Hence, these blue colonies should have been transformed with the plasmids which have no target gene inserted. The plasmids have just replicatedthemselves.In addition, some colonies remain white. This implies that they did not producefunctional beta-galactosidase and hence did not metabolise the substrate X-gal and no blue precipitates/pigments are formed. Hence, these white colonies should have been transformed with the plasmids which have the target gene inserted and hence its LacZ gene is disrupted.VIII.Discussion1.After heat shock [Part (1) of the experiment, Step 21] the tubes were mixed by using“finger-flicking” or “wrist-flicking” instead of vortexing. Suggest the reason for this.Calcium ions enhance the permeability of the bacterial cell membrane.The heat shock step further weakens the cell structure.Vortexing exerts a shearing force to cells, which breaks the cells and causes cell death.It is necessary to mix the cells using milder methods.2.During the heat shock step, a student accidentally heated the cells at 42o C for 5 minutes.Only a few colonies were found on the agar plates at the end of the experiment. Explainthe results.During transformation, the cellular structure of the bacteria was weakened. Prolongedheating damaged the cells and caused cell death.3.What are the functions of X-gal and IPTG in blue-white screening?X-gal is actually the substrate of the enzyme β-galactosidase. Upon enzymaticmetabolism, X-gal is degraded into products with blue pigments. IPTG is used to inducea strong expression of the LacZ gene in bacteria.IX.ReferencesJulin, D. A. (2018).
